Software
I’m an architect who cares who the product is for. I take ownership of complex systems, and I prove they work with tests written in the language of the product.
What sets me apart
I start from what users need, then work back to the architecture.
Acceptance tests in the language of the product make big rewrites safe.
Boundaries, linting, and pipelines checked by tooling, not good intentions.
I take on untested, half-finished systems and turn them into a plan.
Professional work
