Shipped fast and things are breaking?

I turn shipped-fast into built-to-last.

Let's Talk

Backend Engineer & AWS Architect

I build systems
that hold up.

Scalable backends. Clean infrastructure. Code your team can live with.

Sound familiar?

01

Your API slows to a crawl as you grow. Nobody knows exactly why.

02

Cloud costs rise quietly every month. Your team is too busy to stop them.

03

Your services hold together — until they don't. One bad deploy, and everything follows.

Services

Backend Architecture & API Development

The best backend code is the kind nobody talks about. Fast, stable, easy to change — and built for the team that has to maintain it.

Cloud Infrastructure & AWS

Cloud infrastructure that earns its cost. Right-sized for now, ready for what comes next.

Data Pipelines & Analytics

Data is only useful when it moves reliably. Pipelines built for production — processing millions of events without drama.

Technical Consulting & Code Review

A second opinion from someone who's been in the weeds. Honest assessment, no slide decks. Whether you're scaling, refactoring, or buying a system — clarity first.

Work

Analytics Pipeline

Built an end-to-end analytics pipeline that gave clients real visibility into how people engage with their 3D experiences. Events flow from client to insight without friction.

Multi-Tenant SaaS Platform

Designed and built the backend for an AI-powered platform serving 3D and AR experiences to enterprise clients. Multi-tenant from day one, built to grow.

Cloud Architecture & Cost Optimization

Owned the AWS infrastructure for a scaling SaaS product. Kept it reliable, kept the costs honest, kept the team unblocked.

End-to-End Project Leadership

Led projects from blank file to production. Set the architecture, guided the team, and stayed accountable through delivery.

Technical Advisory & IT Consulting

Worked alongside enterprise clients to make sound technical decisions — not just good engineering ones. Translated business needs into systems that actually got built.

Mentorship & Team Development

Brought junior engineers from onboarding to production-ready. Code reviews, architecture talks, real ownership — the kind of mentorship that sticks.

If something feels fragile,
let's fix it properly.

Rising costs, scaling trouble, architectural debt — a short call is usually all it takes to get clear on what to do next.
