// senior software engineer
I build and integrate production fintech and public-sector platforms — full-stack, from API to UI.
AutoWealth · fintech
problem · Automated investing only works if trades execute reliably across multiple brokers — each with a different API, settlement model, and failure mode.
solution · Built and maintained the integrations with Moomoo, iFAST, and Phillip Securities end to end — order execution, portfolio sync, and reconciliation — plus legally binding e-signature onboarding via Dropbox Sign.
Gov careers platform · microservices
problem · Surface the most relevant articles and events to each job seeker, with the underlying data spread across four independent services.
solution · Designed a personalised recommendation engine that scores content against each user's career persona and interest tags, coordinating across four microservices over a RabbitMQ message bus.
AutoWealth · modernization
problem · A mature, revenue-critical PHP platform had to move to a modern stack without disrupting live clients or pausing feature work.
solution · Helping migrate the codebase toward React / Next.js + Node.js incrementally — shipping new features on the modern stack while progressively replacing legacy screens and services.
Side projects I designed, built, and shipped end-to-end — data layer, UI, tests, CI, and production deploy. Both are live and open-source; click through to use them or read the code.
