About this gig

High-performance, scalable backend services built with Golang. I specialize in ultra-fast, concurrent systems, real-time data, and robust database integrations.


What I offer:

  • Real-Time Architecture: High-concurrency WebSockets and event-driven data streaming.
  • APIs & Protocols: Secure RESTful APIs, gRPC, and custom microservices engineered using Gin, alternative frameworks, or standard Go tools.
  • Integrations: Seamless setups with PostgreSQL, Redis, and crypto payment gateways.
  • Code Fixes: Deep debugging, refactoring, and performance optimization.


Commercial-grade, production-ready code focused entirely on speed, efficiency, and security.
