01 / About

A developer who connects interface polish with reliable systems.

I'm a full-stack software developer focused on building scalable, data-driven applications with Java, Python, React, and AWS. I care about clean code, automated testing, practical problem-solving, and clear communication with both technical and non-technical teams.

Product-minded engineering

I build interfaces with the full workflow in mind: clear interaction states, accessible structure, and implementation details that hold up in production.

Full-stack context

My work spans React, Next.js, APIs, databases, and cloud-hosted services, which helps me connect UI decisions to system behavior.

Practical problem solving

I am comfortable debugging production issues, reading logs, improving reliability, and turning ambiguous requirements into shipped features.
