About Oguzhan

Looking for a Go or Node.js backend developer to deliver quickly and efficiently? I design APIs, microservices, and containerized distributed systems with Docker and Kubernetes, from MVP to scale-up.

Most projects fall behind because we over-architect from the start. My approach: deliver simple, deliver fast, then iterate. That's how I deliver a complete backend (70+ endpoints) in 1 month.

What this means for you:

*Your backend holds up: REST APIs in Node.js/Fastify or Go, PostgreSQL, MongoDB, GraphQL. I've run financial flows of tens of millions of euros in fintech and OSINT scraping at thousands of requests/day. When it shouldn't go down, it doesn't.

*One point of contact, not three: React, Next.js on the web, React Native on mobile, from API endpoint to UI component. Less back-and-forth, less friction, more velocity.

*What's coded is deployed: Docker, Kubernetes, AWS, Terraform, GitHub Actions CI/CD. I don't deliver a zip file by email. Code is deployed multiple times a day.

*Architecture follows needs, not hype: microservices, event sourcing, serverless; each choice is justified by your context and budget. A well-built monolith is better than a microservices Rube Goldberg machine.

Lately: MVPs delivered from scratch in a few weeks, migration of legacy systems to Go to handle increased load, and backend services in fintech. From early-stage startup to scale-up.
