Full-Stack Software Engineer · React / .NET / Python
San Jose, CA

I build 0-to-1 consumer products end-to-end — from React frontends to .NET & Python backends running on AWS. Currently the sole full-stack engineer behind Sonilo, a consumer AI music platform built to handle thousands of concurrent users. I care about shipping real products and making complex systems (async pipelines, payments, real-time streaming) feel simple.

Sonilo — Consumer AI music platform  live

Architected and shipped end-to-end with .NET 8 + React, deployed to AWS ECS. Async AI-inference pipelines on Hangfire + Redis, real-time audio via SSE/WebSockets, and an idempotent Stripe payment/credit system on PostgreSQL. Scaled to handle thousands of concurrent users at launch.

lottie-render — Convert Lottie animations to MP4, frame by frame

An open-source renderer built with TypeScript, Playwright and FFmpeg. Try the browser demo without installing anything: preview a Lottie JSON file locally, convert it on the server, and download an H.264 MP4. Integrate the Node.js library, or use the CLI and self-hosted HTTP API from the source checkout.
