About this gig
Need a fast, scalable Go backend, REST API or microservices architecture? You're in the right place!
A poorly built backend slows your product down. With 4+ years of experience in Go, I build secure, high performance backend systems that are easy to scale and maintain. Whether you're starting from scratch, connecting a React/Next.js frontend or breaking a monolith into microservices, I'll build a solution that fits your needs.
What I can help with:
- Custom REST APIs & gRPC services
- Scalable microservices architecture
- High-concurrency Go applications using goroutines
- PostgreSQL, MySQL, MongoDB & Redis
- Database design and optimization
- Dockerized deployments
- React & Next.js integration
- Clean, modular, maintainable code
- Any custom solution you need...
Tech Stack: Go, Python, REST, gRPC, PostgreSQL, MySQL, MongoDB, Redis, Docker, React, Next.js.
Before placing an order, send me a message. We'll discuss your requirements, define the scope and make sure we're aligned on the best solution before getting started.

FAQ
What do you need from me to get started?
I will need a clear brief of your project requirements, business logic, any existing architecture diagrams and details about your frontend. Please send me a message before ordering so we can discuss the exact scope and ensure we are aligned!
Why should I choose Go for my backend instead of other languages?
Go is engineered specifically for high-performance, cloud native applications. Thanks to its powerful concurrency model utilizing goroutines, a Go backend can handle massive amounts of simultaneous traffic with incredibly low latency, making it the perfect choice for scalable microservices.
Can you integrate the new Go backend with my existing React or Next.js frontend?
Absolutely. I specialize in developing custom, well-documented REST APIs and gRPC services that seamlessly connect to modern frontend frameworks like React and Next.js.
Will you help deploy the application once it is built?
Yes, all of my backend solutions are built with deployment in mind. I provide fully Dockerized setups, ensuring your application is containerized and ready to be deployed reliably on any modern cloud infrastructure.
Why is it mandatory to message you before placing an order?
Backend architecture is highly complex and unique to every business. Discussing your project beforehand ensures we fully agree on the deliverables, technology stack, timeline and pricing so that you get exactly what you need without any revisions or delays.
