I work on the Microsoft stack (C#,F#,WPF,WCF, EF, Sql Server), but have had hands-on work with Haskell, Python, Java and c++. ## Work Experience ### Software Engineer @ G-Research Jan 2025 – Present ### Head of Post Trade Systems @ BH-DG Systematic Trading LLP Jan 2018 – Jan 2025 | London, United Kingdom ### VP Team Lead C#/F# @ Barclays Investment Bank Jan 2016 – Jan 2018 | London, United Kingdom Converted from contract to permanent and in Dec 2016 was asked to lead the team of 5. Projects included F# excel function migrations (from c++), build out and demos of F#/WCF out of process framework for loading user function libraries, working with quants on writing F# functions for Excel to wrap their new Omega functional library, python poc.

The library is a combination of c++, c# functions (c++ are being migrated to c#) and now F# functions, with WPF UIs. My main task was extend and productionise the prototype F# framework, and migrate functions to it. Most users are still on Excel 2007, which has limitations for power users, so we have developed an out-of-process WCF server that can run on the user’s pc or a remote server. The F# framework had a WPF UI for wrapping the user’s F# libraries, I refactored it to MVVM and extended it. The development environment is VS 2015, .net 4.5, git/stash (Bitbucket Server), nexus, TeamCity. We have just migrated from Perforce to git/stash. A Sql Server 2012 database supports our user analytics. ### Cloud and Mobile study @ Self-Study Jan 2015 – Jan 2015 Azure platform Mobile (Xamarin, PhoneGap) Other MS technologies - WinRT, Lightswitch, Cloud Apps, Win 8.1, Win 10 ### VP Equity Finance Development Manager @ Barclays Capital Jan 2013 – Jan 2015 | Singapore Built WPF/Prism-based (in-house Monaco framework - Prism, Reactive Extensions, Unity, Infragistics, and AvalonDock) near real-time position management UI for HKG and TKY desks, to replace Alpha tool mentioned below.
