I build and operate NestJS microservices, production infrastructure, and admin tools for FitSo.
VietnamWhat I'm looking for
At FitSo Hub Innovation, I own the core production backend for FitSo, a wellness and social startup. I maintain a 33-module, approximately 68K-LOC NestJS and TypeScript monorepo using MongoDB and Redis, and led its transition toward microservices.
I run the production environment across Docker Compose, Traefik, and Ubuntu LTS servers, focusing on lean infrastructure for a startup budget. I also build responsive admin dashboards and operational websites, and stepped into SwiftUI work to ship iOS screen updates and logic fixes during a staffing gap.
Previously at An Phu Viet, I coordinated a four-person intern team delivering JectHub. I integrated third-party camera SDKs into a WinForms application for real-time monitoring and prototyped backend architecture for high-volume data processing.
I enjoy owning systems end to end, from API and database design through deployment, infrastructure, and operational tooling. Outside work, I experiment with Rust and RP2040 development on Raspberry Pi Pico from Arch Linux.
