Focused engagement
React Native App Audit

Engineering With Product Judgment
I bring senior engineering depth plus a founder's understanding of product, marketing, and commercial tradeoffs. That means fewer handoffs, clearer decisions, and software built around the real business problem.
You work directly with me—no account managers, subcontracting or handoffs.
