Full-stack engineer with 5 years building and owning production web platforms as a long-term independent contractor. I take products from architecture through deployment to growth — most recently building a trading-analytics SaaS from zero to 10,000+ users. Deep in Python (Flask/Django), React/Next.js, real-time systems, and AWS.

Focus
I'm a long-term independent contractor who runs concurrent client engagements end-to-end — architecture, implementation, deployment, and the growth work that comes after launch. Each engagement is a dedicated, multi-year relationship rather than a one-off gig, which is how I've shipped and owned production platforms used by tens of thousands of people.
My range spans the whole stack: Python backends (Flask/Django), real-time systems with WebSockets, React/Next.js front-ends, and the AWS and Windows Server infrastructure underneath. I'm equally comfortable moving fast with modern AI-assisted tooling and getting hands-on with first-principles engineering when a problem demands it.
Most recently I built a trading-analytics SaaS from zero to 10,000+ users — architecting the platform, replacing costly third-party dependencies with in-house systems, and owning everything from billing to infrastructure cost.
