I build and ship full-stack web products from architecture to production.

About & Approach

I’m a product engineer who helps businesses build software that actually works for their users. I take ideas from concept to production and make sure what ships is worth shipping.

Over the past several years, I’ve built web applications across hospitality, compliance management, testing platforms, and e-commerce. When working with founders and engineering teams, I prioritize writing maintainable code, solving real operational bottlenecks, and shipping reliable products on schedule.

Primary stack: TypeScript, Node.js, Go, React, Next.js, Hono, PostgreSQL, SQLite, Cloudflare Workers, and Docker.

What I Build
0-to-1 Web Applications

Taking product specs from concept to production. Relational schemas, authentication, user role hierarchies, and core user workflows.

Backend APIs & Background Workers

Relational schema design (PostgreSQL, SQLite), REST/RPC endpoints, scheduled cron jobs, transactional email triggers, and webhook listeners.

Data-Dense Dashboards & UIs

Responsive, accessible interfaces for complex operationsvirtualized data tables, multi-parameter filtering, and media handling.

Refactoring & Performance

Legacy codebase modernizations, schema migrations, query performance optimization, and transitioning static sites to full-stack platforms.
