About this gig

Looking for a robust, high-performance backend or microservice built with industry standards? You're in the right place.


I specialize in designing and developing scalable, production-ready backend systems and RESTful APIs using Go (Golang), Node.js, and TypeScript. Whether you need a brand-new microservice or performance optimization for your existing system, I deliver clean, modular, and thoroughly tested code.


What I offer:

* High-performance microservices and REST APIs (Go, Node.js, TypeScript)

* Clean Architecture & SOLID principles

* Database integration & modeling (PostgreSQL, MySQL, MongoDB, Redis)

* Secure authentication & authorization (JWT, OAuth2, API Keys)

* Unit and integration testing for high reliability

* Docker containerization for seamless deployment

* Bug fixing, refactoring, and query optimization


Why work with me?

* Production-grade code with documentation and setup instructions

* Focus on low latency, concurrent processing, and security

* Clear and transparent technical communication


Please message me with your project details before placing an order!
