Full-stack engineer — I build developer tools and real products.
I write open-source tooling — Spoosh, GeckoUI, Whipped — and build production platforms across fintech, real estate and AI that teams depend on every day.
35packages published on npm across every scope, written and maintained solo.
Write the request — the cache takes care of itself.
Every mutation invalidates the right caches automatically. Type-safe API toolkit for React and Angular: routes are typed end-to-end, optimistic updates roll back on failure — all plugin-based.
Commercial real-estate documents, decoded by AI.
Lets a real-estate team ask a question of a loan file and get the answer with the page it came from. Upload loans, leases, and amendments — Notessa extracts every term, cross-references clauses between documents, and answers with page-level citations.
SOC 2 Type II compliant — the product handles confidential loan and lease documents.
Wealth advisory, end to end.
The system a MAS-licensed advisory firm runs its advisers on — plans, clients, commissions, all in one place. Angular and TypeScript: multi-step financial-planning (PFR) workflows with risk profiling, advisor and client management, production analytics, and commission & payroll.
Licensed Financial Adviser and Exempt Insurance Broker, regulated by the Monetary Authority of Singapore — listed in the MAS Financial Institutions Directory.
Institutional real estate, run from one platform.
Asset managers use it to track portfolios, loans and live market rates. Multi-tenant asset management for commercial real estate, built as a Next.js app on AWS, with automated reporting through DocuSign e-signature and an AI assistant wired to 20+ domain tools.
Book a fitting, know your swing.
Books a club-fitting session by store, date and time slot — then shows the golfer what their swing actually did. Fitting companion app for VICX Golf, a Korean golf retail chain: swing-consistency analytics and bag management, React Native on iOS & Android, with Kakao · Naver · Google · Apple login and OTA updates. The app is retired — the shop lives on.
One component library — web and native. Three packages, one API.
Kanban where AI agents do the work. Four backends: Claude, Codex, Opencode, Cursor.
A local app store for utilities forged on demand with Codex.
Browse, book, manage — end to end.
