Full-stack developer / 2026
Product-minded engineering, from interface to infrastructure.
I'm Keith Vuong. I build secure APIs, responsive interfaces, and cloud-ready systems for products that need to work clearly and reliably—not just look finished.
01 / About
I work across the seams.
Between product and engineering. Between the interface users touch and the infrastructure they never need to think about.
I turn business requirements into software that stays understandable as the product grows.
My work covers responsive interfaces, production APIs, authentication, databases, caching, and cloud delivery. I value straightforward decisions, explicit trade-offs, and systems the next developer can reason about.
