Full-Stack Engineer

I design and build full-stack SaaS products — from database schema to deployed UI. Clean architecture, fast delivery, and code that's built to last.

About

Shipping software that holds up under real conditions.

I'm a full-stack engineer with 5+ years of experience building production web applications. I work across the entire stack — system design, API architecture, database modeling, and the frontend layer — and I take ownership of all of it.

My core stack is React and Next.js on the frontend, Python and Django on the backend, with PostgreSQL for persistence. I write code that's readable, tested, and maintainable by the next engineer who touches it.

I work best on product-focused teams where I can contribute meaningfully from day one. I'm async-first, timezone-flexible, and experienced collaborating with distributed teams across the US.

Selected Work

Products I've shipped.

Each project was designed, built, and deployed by me — end to end. Not tutorials, not clones. Real problems, real solutions.

TaskFlow

Project management for lean teams

Built a real-time project management tool to replace overcomplicated tools like Jira for small teams. Includes kanban boards, time tracking, and WebSocket-based live collaboration. Reduced team coordination overhead by keeping the UI out of the way.
