About Me

Hi. I'm Bunlong.

Bunlong

I’m a full-stack developer and solution architect who love turning ideas into applications that actually work. I care just as much about clean architecture as I do about clean interfaces 🙂

I studied Computer Science at the University of Massachusetts Lowell, which gave me a solid foundation in software, infrastructure, and UX.

I can build any web applications end to end, from concept to production, with a strong focus on architecture, reliability, security, and performance. With over 12+ years of experience, I have designed, built, and scaled systems with deep attention to development, testing, deployment, and observability.

I love building Raspberry Pi, Arduino, and robotics projects
