Resume
Software Engineer
I build production systems with AI, payments, and complex data architectures. 10+ products shipped end-to-end. The kind of engineer who can take a product from database schema to production deployment — and make it look good.
Summary
Senior software engineer with 10+ years of experience shipping production applications across AI, fintech, and SaaS. Built and deployed 10+ products end-to-end as sole engineer — real-time AI voice systems, payment processing, multi-tenant data architectures, and performance-critical frontend applications.
Former Head of Design (Vidy, SF) turned senior engineer. Berklee-trained in signal processing and systems design. I bring uncommon product sense to technical execution — the rare engineer who obsesses over both the SQL query plan and the UI animation curve.
Technical Highlights
Experience
Founding Engineer & Lead Architect
phi.llc ↗Phi Digital • Singapore • 2022–Present
- • Architected a scalable backend using Supabase (PostgreSQL with row-level security) and shipped Dayze — a life-tracking SaaS with real-time AI voice (Gemini Live API), Stripe subscription billing, and 120+ API endpoints
- • Designed infinite-scroll "Day Reels" system rendering 10,000+ virtualized items with cursor-based pagination, optimistic updates, and prefetch buffering
- • Engineered real-time AI voice system on Google Gemini Live API — optimized streaming latency, managed context window persistence across sessions, and implemented prompt engineering for domain-specific responses with interrupt handling
