I Build Production Systems
End-to-End

Full-stack and platform engineer with 10 years of experience — from backend APIs and cloud infrastructure to polished frontend experiences. Recent work spans subscription platforms, AI-powered document generation, and multi-tenant SaaS products. I ship across the full stack (TypeScript, React, Node.js, PostgreSQL, Docker, Kubernetes, AWS) and I'm comfortable owning features from architecture through deployment. Available immediately for full-time, contract, or consulting roles. U.S.-based entity — no visa sponsorship needed.

Track Record

What I've Built

Production systems across the full stack — backend APIs, cloud infrastructure, frontend experiences. What I'm good at: building reliable services, shipping features, and working across the stack to get things into production.

Technical Lead & Engineer · Solo Project Sep 2023 – Mar 2026

Radshim

Built and operated a globally distributed subscription platform as sole developer. Designed and ran a 100-node server fleet across 20 countries on Linux — provisioning, load balancing, health checking, automated failover, and zero-downtime deployments. Scaled to 5,000+ paying subscribers and 100K+ transactions. Full codebase published as open-source on GitHub. Platform paused due to regional internet restrictions.

About

Who I Am

I'm a full-stack and platform engineer with 10 years of experience building production systems end-to-end — from backend APIs and cloud infrastructure to polished frontend experiences.

My recent work spans subscription platforms, AI-powered document generation, and multi-tenant SaaS products. I've shipped across the full stack (TypeScript, React, Node.js, PostgreSQL, Docker, Kubernetes, AWS) and I'm comfortable owning features from architecture through deployment and monitoring.

What I'm good at: building reliable backend services and APIs (Node.js, NestJS, GraphQL, REST), frontend development with React, Next.js, and TypeScript, infrastructure and DevOps — CI/CD, Docker, Kubernetes, Terraform, observability — and working across the stack to ship features that actually reach production.

I've also led engineering teams and run architecture reviews — but I'm equally happy heads-down writing code and solving hard problems.

On StackOverflow, I've earned 11,000+ reputation — placing me in the top 1% of all users — with 4 gold badges and 13M+ developers reached. See my StackOverflow profile →

Looking for my next role.

If you're building something interesting and need an engineer who ships across the full stack — from backend APIs through deployment and monitoring — I'd love to talk.
