Yusuf Dariyemez
About this gig
Need a reliable Go backend, REST API, or third-party integration?
I am a Senior Software Engineer with 6+ years of professional experience building production systems with Go, PostgreSQL, MongoDB, Kafka, RabbitMQ, Redis, Docker, and Kubernetes.
I can help you with:
- Developing REST APIs and backend services in Go
- Adding new endpoints to an existing project
- PostgreSQL or MongoDB integration
- JWT authentication and role-based authorization
- Third-party API, webhook, and payment integrations
- Bug fixing, query optimization, and performance improvements
- Unit and integration tests
- Swagger/OpenAPI documentation
- Docker and Docker Compose setup
I focus on clean architecture, secure implementation, predictable error handling, and maintainable code. Every package includes the source code, and the scope is defined clearly before development begins.
Please message me before ordering if your project involves a complete SaaS backend, microservices, Kafka, payment systems, or complex integrations. I will review the requirements and prepare a custom offer.

FAQ
Should I contact you before placing an order?
Yes. Please send me a short description of your project, the current technology stack, and the work you need. This allows me to confirm the scope, delivery time, and correct package before you place an order.
Can you work on an existing Go project?
Yes. I can review an existing Go codebase, add new endpoints, fix bugs, improve database queries, refactor modules, write tests, and integrate external services. Repository access and clear setup instructions may be required.
Which Go frameworks do you work with?
I work with Gin, Fiber, Echo, the standard net/http package, and custom Go architectures. I can also follow the framework and coding conventions already used in your project.
Which databases do you support?
I primarily work with PostgreSQL and MongoDB. I also have experience with MySQL, Microsoft SQL Server, Redis, Bun, GORM, raw SQL, and pgx.
Can you integrate third-party APIs and webhooks?
Yes. I can integrate REST APIs, payment providers, webhooks, email and SMS services, object storage, authentication providers, and other external systems. Complex integrations may require a custom offer.
Do you provide API documentation and tests?
Yes. Depending on the selected package, I can provide Swagger or OpenAPI documentation, unit tests, integration tests, Docker configuration, database migrations, and setup instructions.
Can you build a complete SaaS backend or microservice?
Yes, but complete backend systems vary significantly in scope. Please message me with your requirements so I can review the architecture, features, integrations, and delivery schedule and prepare a custom offer.
