About

Engineer who treats product quality like a craft.

I’ve spent the last five years at Devsinc and on Upwork helping product teams turn complex Figma mocks, ambitious roadmaps and legacy monoliths into fast, reliable software. I care about the boring details — accessibility, types, error states, p99 latency — because they’re what users actually feel.

Recently I’ve led the design of microservice architectures on GCP, migrated CRMs to SingleStore, built AI prompt tooling on top of OpenAI + WebSockets, and shipped React Native apps live on the App Store and Google Play.

How I work

A clear path from idea to production.

No black box. Each phase has a clear deliverable, explicit timeline, and a moment where you can change direction without sunk cost.

  1. 01 — Discovery

    Understand the problem

    We map the goal, users, constraints and success metrics. I’ll push back early on scope to make sure we’re building the right thing — not just building things.

    Day 0 — 1 week

  2. 02 — Design & Architect

    Plan the smallest path to value

    Wireframes, data model, API contracts, infra choices. You see the whole shape before we write production code, with explicit trade-offs flagged.

    1 — 2 weeks

  3. 03 — Ship the MVP

    Production-ready, day one

    Iterative weekly demos. TypeScript end-to-end, real CI/CD, real auth, real monitoring. No throwaway prototypes — what ships is what scales.

    3 — 8 weeks

  4. 04 — Iterate & Scale

    Measure, learn, harden

    Performance, observability, infrastructure tuning, hand-off documentation. Stay on as a fractional lead or pass the keys cleanly to your team.
