Engineering Approach

A few principles that shape how I build and ship software.

End-to-end ownership

From requirements and data modeling through APIs, integration, deployment, and production debugging.

Production-first mindset

I care about reliability, error handling, and observability — not just getting code to run locally.

Practical solutions

I build for real business constraints — time, budget, existing systems — not theoretical purity.

Works with legacy code

I can join an existing codebase, understand it quickly, and improve it without breaking things.

Thoughtful use of AI

I use AI tools where they genuinely help, while reviewing and validating every output before shipping.
