How I work.
Principles
A few things I hold to on every project, regardless of stack or team.
End-to-end ownership
I take features from database schema and API design all the way to the pixel-perfect UI — no hand-offs lost in translation.
Performance-minded
Optimized EF Core queries, leaner request cycles, and healthy Core Web Vitals. Fast isn't a feature — it's the baseline.
Clean & tested
Reusable components, sensible patterns, and NUnit + Moq coverage so shipping stays calm and deployments stay boring.
Design-aware
Comfortable in Figma and motion. I sweat the micro-interactions and accessibility that make an interface feel effortless.
Let's build something great.
