FAQ
What information do you need before starting the project?
Please provide your project requirements, required API endpoints, database preferences, authentication requirements, and any existing code or documentation. Contact me before ordering so we can confirm the scope.
Which technologies do you work with?
I primarily work with Golang, Gin, PostgreSQL, MySQL, SQLite, Redis, GORM, Docker, and REST APIs. I can also work with existing Go projects and integrate third-party services.
What counts as one API endpoint?
Each unique API route and HTTP method counts as one endpoint. For example, GET /users and POST /users are considered two separate endpoints.
Can you work on my existing Golang project?
Yes. I can add new features, develop APIs, fix bugs, optimize database queries, improve performance, and refactor existing Go backend applications.
Can you build a complete backend from scratch?
Yes. I can design and develop a complete Golang backend based on your requirements, including APIs, database integration, authentication, Docker setup, and application architecture. Please contact me for a custom offer for larger projects.
Do you provide the complete source code?
Yes. The complete source code for the work included in your order will be provided upon delivery.
What if I need more API endpoints than my package includes?
Additional endpoints can be included through Gig Extras or a custom offer. Contact me with your requirements, and I can provide an appropriate quote based on the complexity and scope.
