Optiver Asia Pacific

• Software Development Manager

  • Apr 2010 - Jul 2016

  Led the Software Development Team at Optiver, building low latency trading systems for the financial markets across Asia. Optiver is a private trading company and market maker using custom built software to obtain a competitive edge. Over time, the Development Team consisted of 10-15 sub-teams, focussing on Exchange Connectivity, Auto-trading Strategies, Trading UIs, Trading Risk, Core Trading Infrastructure, Middle Office Reconciliation and Quality & Continuous Delivery. After 5 years of growth, and a major re-structure, I split my role so I could focus on the core systems technology shared by the Trading groups, to allow me to remain connected to the work with a manageable team size of ~40 developers. Key Achievements - Sustainably grew the team from 30 to 100+, whilst improving standards, team culture and dev practices. - Persisted to embed a quality culture, improving the maturity and efficiency of delivery, whist reducing risk to Trading. - Key leader, along with the CEO and Local Management Team to introduce a 'Tribe and Squad’ based organisational structure (inspired from Spotify), to address communication and prioritisation issues, and setup the organisation for planned growth. - Significantly changed the dev team from a private culture to be more involved in the community. Brought in meet-ups (such as YOW! nights) to be hosted internally, which led to many more groups following. - Pushed technical innovation to move from only C++ and C# to Python and Go where appropriate and even some Haskell experiments. - Drove a CD initiative to use modern tooling to automate the provisioning of environments and pipelines for building, testing and releasing software. - Improved team cultures by promoting agile practices and collective code ownership, from the initial single person ownership model. - Introduced Innovation Days to allow developers to be creative and technical prototypes in one day. Led to several initiatives being followed through to production ideas. Show less
