HOW I WORK Leading engineering taught me an expensive lesson early: the constraints nobody asks about in week one become the rebuild in week six. So I ask first, then build. You get regular progress updates without chasing me, and code another engineer can pick up without an apology. My clients say the same — clear communicator, reliable, committed to quality. Send me your scope or your current pain point, and I'll tell you honestly whether I'm the right fit and roughly what it'll take.
