Software Engineer. I build fast, accessible and memorable web products — from the database to the last pixel.
I'm a software engineer with a product mindset. I design and build modern web applications where solid engineering meets a polished user experience.
I work end-to-end: architecture, performance, animation and the small details that make a product feel right. I value simple code, fast iteration, and shipping over talking — good ideas prove themselves in production.
AI tooling and continuous learning are part of how I ship. Claude, Copilot and the rest of the ecosystem are daily companions — leverage, not gimmicks. I keep a close eye on what's new because the toolset of an engineer in 2026 looks nothing like 2022, and standing still isn't an option.
I treat AI tooling as leverage. It compresses the boring parts so I can spend my time on architecture, judgment calls and the details that actually matter. The toolset moves fast — staying current is part of the job.

Get to the real problem before reaching for code. Ask the right questions, look at the data, write down the assumptions.
Design
Pick the simplest design that can grow. Document the trade-offs, not the trivia. Optimize for the team that will read this in a year.
Build
Tight feedback loops, tests where they matter, no broken windows. Quality starts at commit zero, not at the end.
Ship & learn
Release early, watch what happens, iterate. The best version is always the next one — but only if this one is in production.
