About this gig

Need a fast, reliable backend in Go? I'm a backend engineer with 5+ years of experience building APIs and event-driven systems with Golang, Kafka and MongoDB.


I've built order, returns and courier-tracking systems for an e-commerce startup handling 5,000+ orders a day, and I currently work on data pipelines and CRM integrations for a US marketing platform used by major retail brands.


What I can build for you:

- REST APIs and microservices in Go

- Kafka producers, consumers and event pipelines

- MongoDB schema design and query optimisation

- Third-party API and webhook integrations (payments, couriers, CRMs)

- Bug fixes and performance improvements in existing Go code


What you get:

- Clean, well-structured Go code

- Clear documentation and a Postman collection

- Dockerfile for easy deployment

- Regular updates and on-time delivery


Please message me before ordering so we can agree on the scope. I usually reply within a few hours.
