Engineering Approach

Start Narrow, Then Generalize

I'd rather solve one team's problem completely than five teams' problems partially. The first case is chosen for what generalizes; everything I learn building it decides what the platform becomes. A single-framework tool turned into a multi-framework ecosystem that way — the abstraction earned, not assumed.

Accessibility as Engineering

Accessibility as an afterthought is the expensive version. Caught in requirements it's a design decision; caught in production it's a remediation effort across 100+ teams. I build agents that live throughout the SDLC so the check happens where the cost is lowest — before anything ships.

Force Multiplier

I've led and mentored 15+ engineers across 3 teams. The measure of that work isn't what I shipped, it's what they ship after.

Shared Definition of Done

Applied scientists measure accuracy, PMs measure customer impact, leadership measures risk and timeline. Most cross-team friction isn't disagreement, it's three definitions of done nobody reconciled. Getting that agreement first is what makes the rest of the work straightforward.
