About this gig
Most freelancers write code. I build systems that run businesses.
For the past 2+ years I've been the sole engineer behind the critical infrastructure of multiple companies: their central management platform, server orchestration system, public API and infrastructure nodes. Designed, built, deployed and maintained all of it, alone, in production, with real users depending on it every day. I also build and run my own SaaS product, so I know what "production-ready" actually means: monitoring, failure modes, third-party dependencies that break at 2 AM.
What I deliver:
- RESTful APIs and microservices in Go
- Backend services and data processors
- Payment integrations (Stripe and similar)
- System optimization and refactoring of existing Go codebases
Why Go? Simplicity, raw performance and first-class concurrency. The right tool for systems that need to stay fast and maintainable as you grow.
How I work: Clear scope before any order. Honest estimates, if your project doesn't fit my packages or my skills, I'll tell you upfront instead of wasting your time. Source code and deployment instructions always included.
Prices shown are estimates. Message me with your requirements before ordering.
