About this service

Summary

I offer professional Golang API development services, building scalable and high-performance RESTful APIs with clean architecture and best coding practices. My expertise includes integrating secure authentication, database design, and comprehensive API documentation with Postman collections for seamless testing. With a focus on efficiency and maintainability, I ensure a robust backend solution tailored to your business needs.

Process

Requirement Gathering & Planning The project begins with a detailed discussion to understand the client's requirements, including API functionality, authentication needs, database structure, and expected integrations. A clear development plan and timeline will be established before proceeding.
API Design & Architecture Setup The API structure is designed based on best practices, choosing a suitable Golang framework (Gin) and defining the data flow. The database schema is planned, and authentication mechanisms (JWT, OAuth, or API keys) if required, are outlined to ensure security and scalability.
Development & Implementation The backend development process includes coding API endpoints, integrating database connections, implementing authentication, and optimizing performance. The code follows clean architecture principles, ensuring maintainability and efficiency.
Testing & Debugging The developed API undergoes rigorous testing, including unit testing, integration testing, and manual testing using Postman. Bugs or issues are identified and resolved to ensure the API functions correctly and securely.
Documentation & Postman Collection A comprehensive API documentation is created, detailing endpoints, request/response formats, authentication methods, and usage guidelines. A Postman collection is also provided for easy testing and integration.
Deployment & Handover The API is deployed to a server or cloud platform based on client preferences. A deployment guide is provided to assist with future updates and maintenance. The final deliverables, including source code, documentation, and database scripts, are handed over.
Revisions & Support Minor revisions are offered based on the agreed scope to fix bugs or make small adjustments. Post-project support is available for guidance on API usage and deployment.

What's included

  • RESTful API Development (Go + Gin)

    Clients will receive a fully functional RESTful API built using Golang with a chosen web framework (Gin). The API follows best coding practices with a structured architecture (MVC or Clean Architecture) and includes authentication (JWT, OAuth, or API keys) if required. The deliverable will be provided as source code in a GitHub repository or a ZIP file, including 5-10 endpoints. Up to 2 minor revisions for bug fixes and optimizations are included.

  • API Documentation & Postman Collection

    A detailed API documentation will be provided, outlining available endpoints, request/response formats, and authentication methods. Additionally, a Postman collection will be included for easy testing. The documentation will be delivered in Markdown or PDF format, and the Postman collection as a JSON file. One revision is available for documentation updates.

  • Database Integration & Deployment Guide

    Clients will receive a database schema designed for PostgreSQL/MySQL, along with SQL scripts or migration files for setup. A step-by-step deployment guide will be provided to help with API deployment on a server or cloud platform. The deliverables will be in the form of SQL scripts and a Markdown/PDF guide, with one revision available for minor schema adjustments.
