How I Work

Straightforward scoping, iterative milestones, clear documentation, and a bias for maintainable solutions your team can own. I’m comfortable partnering with non-technical stakeholders and jumping into messy systems to create order and momentum.

Let’s build something useful. Quickly, securely, and with measurable impact.

Portfolio: GitHub (ML projects), interactive mapping.
