What you get:
A production-grade backend system engineered for speed, reliability, and scale. Not a tutorial project. Not boilerplate stitched together. Every API I build is hand-architected for your specific use case, load-tested, documented, and ready to handle real traffic from day one.
You'll walk away with clean, maintainable code, a comprehensive API reference manual, and a backend that doesn't flinch under pressure.
I build in your language:
Go (Fiber) - When you need raw speed and minimal overhead. Ideal for high-concurrency systems, microservices, and anything that needs to handle thousands of requests per second without breaking a sweat.
Python (FastAPI / Flask / Django) - When you need rapid iteration, ML/AI integrations, or a battle-tested framework with a massive ecosystem.
TypeScript/JavaScript (Express / Elysia.js) - When your frontend team lives in the JS ecosystem and you want a unified stack with type safety end to end.
I don't push a single stack on every project. I pick the right tool for your problem.
My process:
Architecture session - We map out your data models, endpoints, auth strategy, and scaling requirements. I ask the hard questions upfront so there are zero surprises later.
Development - Modular, testable code with proper error handling, input validation, rate limiting, and logging baked in from the start. Not bolted on as an afterthought.
Documentation - You get a complete API reference manual: every endpoint, request/response schema, auth flow, error codes, and example calls. Your frontend team (or your future self) will thank you.
Delivery - Deployed, tested under load, and handed over with full source code and deployment instructions.
What I've built:
Roule.io - High-performance backend powering real-time interactions at scale
BrokenGPT - AI-integrated backend with complex API orchestration and data pipelines
SkillSynx - Full backend architecture handling user management, skill matching, and dynamic data processing
Best for:
Startups that need a backend that won't collapse at 10x growth
SaaS products that need clean, documented APIs their frontend team can actually work with
AI/ML products that need robust data pipelines and model-serving infrastructure
Founders replacing a fragile MVP backend with something production-ready
Why work with me:
8+ years shipping production systems. I've built high-concurrency platforms, agentic AI backends, and APIs that serve millions of requests. I write the architecture docs, I write the code, I write the tests, and I hand you something you can build on for years. One engineer, zero handoff friction.
