I SHIP
AI-POWERED
PRODUCTS
Software engineer who builds and ships production AI products. Real-time voice AI, payment systems processing live transactions, and complex data architectures — not side projects, but products serving real users.
By The Numbers
What I've Built
Production Systems • Live Users • Real Revenue
Dayze
Life tracking SaaS I architected and shipped solo. The hard engineering problems:
- → Real-time AI voice assistant via Google Gemini Live API with streaming audio
- → Infinite scroll "Day Reels" rendering 10,000+ days with virtualized loading
- → Stripe subscription billing with webhooks, pro-gating, and customer portal
- → Row-level security on PostgreSQL via Supabase with multi-tenant data isolation
- → Admin dashboard with real-time chat monitoring and user analytics
Cryptography
Web3 Wallet System
4 wallet providers, 6 EVM chains, server-side signature verification. Complex state machine with 12 action types.
Real-time Systems
ACID-303
Browser synthesizer with sub-millisecond scheduling. Web Audio look-ahead pattern, 60fps Canvas rendering.
Payments Platform
Concert Festival ↗
Event booking with live Stripe payments, application workflow, admin panel, WhatsApp integration.
Technical Depth
AI & Real-time Systems
Production AI voice integration
Built real-time voice AI with Google Gemini Live API — bidirectional audio streaming, interrupt handling, context persistence across sessions. Also: sub-millisecond audio scheduling with Web Audio API look-ahead patterns, 60fps Canvas rendering.
Data Architecture
PostgreSQL + Row-Level Security
Designed multi-tenant data models with Supabase RLS policies, optimistic updates via SWR, infinite pagination with cursor-based loading across 10,000+ records. Also: Prisma migrations, Firebase real-time sync, complex relational schemas.
Payment Systems
Stripe end-to-end in production
Checkout Sessions, Subscription lifecycle (create, upgrade, cancel, resume), webhook event processing, Customer Portal, feature-gating by plan tier. Processing live payments on multiple products.
Web3 / Cryptography
Multi-chain wallet system
4 wallet providers (MetaMask, WalletConnect, Coinbase, Phantom), 6 EVM networks, server-side signature verification via ethers.verifyMessage. Complex state machine with Context + useReducer (12 action types).
What Makes Me Different
I've shipped entire products solo
Not components. Not features. Entire products with auth, payments, AI, admin dashboards, SEO, and deployment. I understand how every layer connects because I've built every layer.
Production AI, not demo AI
Real-time voice AI serving live users via Gemini Live API — with interrupt handling, context persistence, error recovery, and pro-tier gating. Not a hackathon project.
Design eye + engineering depth
Former Head of Design at Vidy (SF). Berklee College of Music graduate. I ship polished, accessible products — not just working code. The rare engineer who cares about the pixel and the query plan.
Interested?
Selectively exploring senior engineering roles at companies building ambitious AI products, fintech platforms, or developer tools.
I'm most effective on teams where engineers own outcomes, not tickets. Singapore-based. Open to remote for the right team.
