API & Backend Development
Service Overview
I build robust, scalable backend systems and RESTful APIs that power modern web applications. Whether you need a Node.js/Express API or a C# ASP.NET Core solution, I deliver secure, well-documented, and production-ready backends — with proper authentication, error handling, database integration, and CI/CD pipelines from day one.
Services Offered
REST API Design & Architecture
Clean RESTful API structure with clear endpoints, proper HTTP methods, and resource naming conventions. Scalable architecture built with Node.js/Express or C# ASP.NET Core — whichever fits your stack.
Database Integration
Full database design and integration with PostgreSQL or MongoDB. Schema design, migrations via Entity Framework Core or Mongoose, query optimization, and production-ready data models.
Authentication & Security
JWT-based authentication, role-based access control, BCrypt password hashing, and protection against common vulnerabilities. Security built in from the start, not bolted on later.
Testing & Documentation
Integration tests with Jest + Supertest (Node.js) or xUnit (C#). Comprehensive API documentation with Swagger/OpenAPI. Every endpoint tested, every edge case covered before delivery.
Deployment & CI/CD
Docker containerization, GitHub Actions CI/CD pipelines, and cloud deployment. Your backend ships with automated testing, build, and deploy workflows already in place.
Technologies Used
Development Process
Requirements Analysis
I analyze your backend requirements, define API endpoints, plan database schema, and choose the right tech stack — Node.js or C# — based on your project needs. A complete API specification document is created before development starts.
Architecture & Database Design
Clean architecture decisions upfront — data models, relationships, authentication strategy, and API contract all defined before writing code. No shortcuts that create technical debt later.
Development
Backend built with Node.js/Express or C# ASP.NET Core using clean, maintainable code. CRUD operations, middleware, authentication, and error handling implemented with regular Git commits and code reviews throughout.
Testing & Documentation
All endpoints covered with integration tests — Jest + Supertest for Node.js, xUnit for C#. Swagger/OpenAPI documentation generated. Every status code, error scenario, and edge case verified before delivery.
Deployment & Support
Docker containerization, GitHub Actions CI/CD pipeline, and production deployment. CORS, environment variables, and security configurations all handled. Ongoing support and maintenance available post-launch.
