About MahiFX
The e-FX Engine Room

MahiFX was formed in 2010 by David & Susan Cooney. Our diverse team has over five decades of collective interbank experience in the disciplines of coding, quantitative analytics, trading and sales.

David, our CEO who was once described as an e-FX heavyweight - an attribute he has tentatively taken as a compliment, for now - has spearheaded numerous FX industry firsts at key influential global investment banks. He and the team continue to drive innovation in the industry.

Our first product, MFX Trade, formally launched in 2012. Meanwhile, work started on our institutional product, MFX Compass, which launched in 2014.

A new and innovative offering to the market, Compass provides institutional clients with all the tools they need to quickly and seamlessly establish a robust e-FX business complete with pricing, technology, analytics and support.

2016 sees the launch of MFX Vector, our third product released under the MahiFX umbrella. Vector is an intuitive, easy-to-use platform that gives complete transparency on live orders, fills and LPs, rate formation and passive execution for the active FX trading community.

Our team

From the outset MahiFX intended to differentiate itself, not only in terms of technology and pricing, but also in terms of the nature, character and expertise of our team. With over five decades of collective interbank experience in the disciplines of coding, quantative analysis, trading and sales, we are uniquely placed to share expertise in a wide range of specialist areas.

The team behind MahiFX

David Cooney, CEO & Co-Founder

A young David Cooney was hoping to become a fighter pilot, racing car driver or an All Black. Although he remains adamant that he still has the ability to do all of these even to this day, he thought it best to begin his career as an interbank spot foreign exchange broker in his native New Zealand. After landing a role as a currency options trader, David moved to London, where he worked for Chase Manhattan and later, Credit Suisse. This was followed by roles at Dresdner Bank in Singapore, where he took charge of the currency options operations for Asia before moving back to London as Dresdner’s Global Co-head of Currency Options. From there David co-headed the global Options desk at Barclays Capital where he was instrumental in developing the award winning BARX platform. As well as running MahiFX he can be found indulging his passion for aviation and regularly dashing out of meetings to point at helicopters and shout about them.


Susan Cooney, Co-Founder

Being stubborn, bossy, creative and controlling are all the traits of a leader, Susan firmly assures us. Her career started in e-FX at Dresdner Kleinwort Wasserstein, where she was responsible for selling the online trading platform Piranha throughout Europe. This was followed by a move to Barclays Capital where she was given responsibility for European Institutional e-FX clients and later for recruiting and heading a new team of sales professionals to promote Barclay's e-FX trading platform, BARX, to European Institutional Banks and Hedge funds. She is passionate about good design and can often be found obsessing over paper quality and typography, insisting that one letter needs to be moved a millimetre to the left. We can’t see it but we’ll take her word for it.

James Furness
Chief Technology Officer

Read more

James is a Burrito-hunting, turntable-spinning DJ and undercover geek. Since acquiring his first computer at the tender age of five, he has rarely been seen without some sort of gadget at his fingertips. After completing a degree in Computing at Imperial College London he ventured to the University of Manchester to seek a change of student life, and to complete a masters in Advanced Computer Science.

His technology career spans 17 years taking in a diverse range of industries ranging from vehicle telematics to call centre administration systems, however the last 11 years have been focused on the unique challenges of electronic trading. James was part of the team behind Lehman Brothers' award-winning FXLive platform. Post the infamous collapse he moved to the trading floor to join the team developing the hedging/pricing/analytics technology behind Barclays Capital’s BARX platform (one of the top-three FX single-dealer platforms). When he’s not working to improve the MahiFX products (which is rare) he can sometimes be found DJing in one of the many clubs/bars around London.

Andrew Morgan
Lead Developer

Read more

Andrew is coming to terms with being a "veteran" technologist. Having worked in a brand wall of companies: Morgan Stanley,UBS, RBS, BBC News Interactive & Sony R&D he's seen a variety of situations from developing low-latency trading systems to his time as a CTO, carefully balancing management and strategy with advertising optimisation algorithms.

His soft Welsh accent has been dulled by his time at Cambridge University where he read Computer Science just as they introduced studying Java at the university. He claims to appreciate a good glass of wine (perhaps not his 6th) and is an enthusiastic guitarist. Despite being relatively quiet at work, we can always count on Andrew to crack out the first (and last) moves on the dance floor at any staff party; a sight we’ll never tire of seeing.

Zoltan Szel
Lead Developer

Read more

Our fine tech team has expanded again with the addition of Zoltan: a computer wizard and self-certified handyman extraordinaire, complete with a superhero-esque name! Having graduated from a degree in computer science at Eotvos Lorand University of Science, Budapest, Zoltan began his career with Morgan Stanley's Java engineering team. This later led to his move to London into a more finance-oriented role. Following a short stint with RBC, he made his way over to us, where we’re more than happy to have him.

When he’s not sat tapping away at his desk, Zoltan enjoys cycling, watching a good Sci-Fi movie, or heading out into London’s nightlife, where you can be certain that he’ll be the last one standing with a fresh tray of shots. With a diverse and seemingly endless list of talents, from a slightly unnatural ability to annihilate anybody who dares challenge him to a game of chess, to a newfound ability to demolish and landscape his entire garden from scratch, we’re pretty confident that Zoltan is more than capable of solving any problem we chuck his way.

Lee Butts
Lead Developer

Read more

Lee is our resident petrol head and heads up the Christchurch development team. Some say he was raised by sheep, and can only turn left. All we know is he's the Stig's kiwi cousin. He provides critical technical support to his less tech-savvy colleagues, and his two key mantras are 'have you tried turning it on and off again' and 'try Google'. As a founding member of the MahiFX Harriers he is a keen runner and currently holds the MahiFX Half Marathon record.

He has over 15 years of software development experience since graduating from Canterbury University with an honours degree in Computer Science. He has worked in a wide range of industries, most recently in financial services and online advertising. He returned home to Christchurch in 2010 having lived and worked in Australia for eight years.

Ollie Robertshaw

Read more

Ollie is our latest West Country lad to join the team, although sadly refuses to use his accent around us, which we can understand but are nevertheless disappointed at.

Having attended the University of Oxford for five years and becoming a Master of Mathematics, Ollie felt that what he was missing in his life was actually more maths. Therefore, he spent a further four years at the University of Southampton to complete a PhD, specifically researching the ‘oscillations of rotating and magnetic neutron stars using a novel time-and- memory-saving framework suitable for approximately-spherical problems’.

In his spare time, he enjoys studying his family history, and has so far managed to find generation after generation of poor weavers since the 14th Century. Although he’s yet to find any links to royalty, he remains oddly optimistic about that he will eventually do so.

Ollie has a pretty impressive set of IT skills that we won’t argue with, and has plenty of experience in the financial world working for JPMorgan and Daiwa Capital Markets Europe in the past. When he’s not sat working away on his computer, you’ll usually find Ollie feeding his McFlurry addiction, or asking if anybody else would like a McFlurry, in an effort to conceal his need to go and buy another.

Alexander Ridgers
Director of Trading & Analytics

Read more

We cordially present to you Mr Alex Ridgers, providing a touch of class to proceedings. Having spent most of his upbringing in a top hat and tailcoat at Ascot Racecourse with his horse, Weekendatbernies, Alex finally tore himself away to study Business and Economics at Bristol University. Following his graduation, he whipped off his mortarboard and made a beeline straight for London, where he began his career with IG Index PLC as a quoting dealer.

Since then, Alex has added ABN AMRO Bank, CMC Markets, and GKFX to the list of companies lucky enough to have him, under roles such as Head of Algorithmic Trading. Most recently, Alex has been working for Oanda as a trader, focusing on such tasks as model building to back test flow for optimum risk management. Needless to say, with all this experience, we’re pretty smug that he’s jumped ship and come over to Team Mahi.

When he’s not working, you might find Alex lovingly tending to his collection of cigars, some of which date back to the 1970s and are all housed in his very own humidor. If he’s not there, he’ll probably be annihilating some poor soul at a game of Scrabble. This is a game that Alex does not approach blithely, after having appeared on a Scrabble-based game show which saw him achieve the highest first round score of the whole series. We won’t go into the words he used but let’s just say he made the letter ‘X’ look very popular, and no, we’re not sure how to pronounce the words it featured in.

Will Carter
Associate, Analytics

Read more

Joining our ever-growing MahiFX sub-group of rugby players, Will has assumed his position on the Analytics team. Originally from Wales, he first ventured to Manchester to study Physics, and was taught by none other than Professor Brian Cox, as well as a number of Nobel Prize winners, during his degree.

Despite undergoing 24 operations on his leg following a serious injury at the age of 18, Will still went on to become the captain of the university rugby club for two years, and won an award from the university - so he’s well practised in both rugby and necking pints.

After graduating, Will moved down south and we promptly snapped him up. Although a fluent Welsh-speaker, he’s still an avid supporter of the England rugby team – helping us to ensure that we really outnumber David in the London office. Will joins MahiFX as our Analytics Assistant, where he’ll be Alex’s analytics wing-man to support our clients.

Tony Bell
Director, Quality Assurance

Read more

As well as heading the Quality Assurance team at MahiFX, Tony leads a double life as a wannabe pro surfer and Dad to three teenagers. He is also famous for his love of antique Japanese cars, his prize possession being his $200 dollar two tone white and rust 1986 Toyota Corolla. Not embarrassing at all parked outside the MahiFX offices. Day to day, Tony is responsible for ensuring that our products are functional and intuitive as well as serving as a software and hardware tester (attested by the vigorous pounding his keyboard receives, much to the indignation of the disgruntled colleagues who are within earshot).

Tony has had an extensive career both in New Zealand and abroad, namely in London at JPMorgan and SBC Warburg in operations and latterly at Hermes in quality assurance. Upon his return to New Zealand Tony worked at Sungard and Northern Arch in a quality assurance and software design capacity before joining the MahiFX team and helping to build and launch the retail trading platform.

Paul Park
Chief Operational Officer

Read more

Despite his expression in the photograph, we are pleased to announce that this man doesn’t have a single criminal conviction (although we’ve had this checked, just to err on the side of caution). Quite ironically, one of Paul’s jobs as Chief Financial Officer is to monitor compliance here at MahiFX, and he ensures that everything we do is safe and legal. Having spent twelve years climbing the Ladder of Importance at Ernst & Young, Paul jumped ship to MahiFX and since then hasn’t failed to astound us with his tax, legal, finance and capital markets knowledge.

He can usually be found uttering his favourite phrase, “computer says no.” as he repeatedly prevents us from misbehaving, and keeps us on the straight and narrow as best he can. With his dapper sense of style, Paul saunters into the office every morning safe in the knowledge that in one fell swoop, he has reduced everyone else’s choice of attire to the same level as your Saturday morning hangover pyjamas. This competitiveness is something Paul never leaves at home whatever the occasion, so rest assured that we couldn’t find anyone as good at what he does than Paul – he is literally better than everyone.

Nicole Vivian
Compliance & Finance Manager

Read more

Nicole - or “Sparkles” as she is more commonly known in the office due to her love of all things that glitter - is Manager of the MahiFX legal, compliance and finance teams. When she isn’t dragging her colleagues for PB runs round Hagley Park or leading boot camps in the boardroom she plays Mum to two little girls at home (as well as to the boys in the office at work).

Nicole has a double degree in law and accounting, is a qualified barrister and solicitor of the High Court of New Zealand and a Chartered Accountant. Nicole began her career in the corporate tax team at Ernst & Young in New Zealand before moving to London for five years and working for JPMorgan Chase and AXA Corporate Solutions in their tax, compliance and finance teams. Upon her return to New Zealand, Nicole spent a little more time with Ernst & Young again, before moving to Infiniti Capital Markets, embarking on motherhood, and finally joining the MahiFX team in Christchurch.

Liam Cordelle

Read more

Known as the Wakatipu Wizzkid, Liam joined MahiFX as our intern in 2016, building out our automated acceptance suite as part of the QA team. After graduating with a dual bachelor degree in physics and computer science he joined the development team as a full time developer at the start of 2018. 

He is also an up and coming member of the Mahi Harriers, having recently knocked of his first half-marathon in his home town of Queenstown. You will often find him zipping round the city on a lime scooter, sometimes riding two at the same time when he's moonlighting as a Lime Juicer. His current high score is 29.4 kph down city mall while screaming at pedestrians to get out of his way. 

Bonnie Cassidy
Business Relationships and Solutions

Read more

Bonnie has been around, so to speak. During her career she has worked in Swiss, German, and British banks, as well as a brief stint at the Queen’s stockbrokers. She eventually decided it was time for a bit of antipodean action and wound up here at Mahi. Recruited into the infamous Barbie’s Army, Bonnie has an unrivalled collection of anecdotes to tell from her experiences abroad, including the time she went to Lithuania without checking the weather forecast first and promptly arrived in a pair of stilettos.

On meeting the client for the first time, she immediately took a tumble in the snow taking him down with her – suppose that’s one way of, quite literally, breaking the ice. Bonnie also moonlights as a professional shopper, blessed with an incredible ability to navigate most malls blindfolded (if such a situation were ever to arise). She is uber organized, and loves nothing more than a bit of good old-fashioned order; demonstrated by her colour-coordinated wardrobe, and that warning look when our desks begin to look a little messy. With two young’uns, Bonnie currently spends a lot of her time ensuring she’s not covered in things she shouldn’t be, whilst singing Old MacDonald in a faux American accent.

Nicola Clifton
Business Relationships and Solutions

Read more

It took her a while to find us, but after graduating from Loughborough University with a degree in Politics & Economics and a stint behind an equities desk, Nicola eventually saw the light. Joining Team Mahi and embracing all things fun and Forex.

Nicola is a pretty diverse girl, and is certainly no one-trick pony. Her uni days saw her take up a keen interest in flying as a member of the University Air Squadron… that is, until she realised she hated flying. Nowadays, Nicola tends to keep her feet on the ground - usually behind the decks at a fancy London club or bar. This budding little entrepreneur started off moonlighting as a party planner but was repeatedly disappointed by the number of DJs who failed to impress. Nipping the problem in the bud, she combined her love for parties and music with her dislike of other DJs and became one half of a DJ-ing duo. Adding to our growing list of resident Mahi DJs, Nicola ensures that our clients are left wanting for nothing.
