Senior full stack engineer, technical lead

Software that holds up when the stakes get real.

Over the last decade, I have shipped platforms across AI, fintech, education, and marketplaces, from early MVPs to acquisition-scale systems. I work with teams that need calm technical leadership and production-grade execution.

Selected work includes

Bridestory, Schoters, Volt, Umroh.com, Lean Labs, Huntstreet.

Operating profile

Technical leadership, without the theater.

I tend to be most useful when a team has real momentum and real consequences: an AI product that must feel instant, a marketplace that needs to survive seasonal load, or a platform that has outgrown its first architecture.

Over 10+ years, I have moved between hands-on delivery and leadership, serving as CTO, leading engineering teams, and rebuilding systems that needed to scale cleanly without drama.

Lead

Cross-functional planning, architecture direction, and senior execution when the product path needs clarity.

Build

Backend-heavy platforms, AI workflows, customer-facing products, and the connective systems that make them reliable.

Stabilize

Refactors, migrations, cost control, and production hardening once the first version starts to strain.

Technical range

Broad enough to move fast, disciplined enough to keep it coherent.

I work across product and platform layers, but the throughline stays the same: reduce complexity, make the critical path reliable, and leave the system easier to extend than I found it.

Backend

PHP, Laravel, Symfony, Python, FastAPI, Node.js, Express.js, Hono.js, NestJS

Frontend

Vue.js, Nuxt.js, React, Next.js, React Native, Astro, TypeScript

Infrastructure

If the work needs depth, let's talk.

I am open to consulting, senior build work, technical leadership, and complex product delivery. If there is real product pressure, that is usually where I am most useful.

Best fit

  • 0 to 1 products that need experienced architecture from the start.
  • Teams rebuilding a platform that has become fragile, slow, or expensive to change.
  • Founders or operators who need a senior technical partner for AI-heavy or systems-heavy work.
