What I'm looking for

I'm looking to build high-impact full-stack products, especially learning or fintech systems where scalable backend work and thoughtful user experiences matter.

I've built backend systems for Click SuperApp, serving 12M+ users, including a push-notification pipeline that reaches millions and a MongoDB path handling roughly 2,000 connections per second.

At TaleTalk, I build React and Flutter clients on a NestJS API for language learning, including retry scoring and Kokoro TTS caching. I also mentored 50+ Udacity students through 250+ full-stack deployments and bring 12 years of fluency-first English curriculum design.
