Available for Hire & Full-Stack Projects

Hi, I'm Kulin Rangani

|

Building scalable web applications, real-time multiplayer systems, AI-powered assistants, and business management platforms with clean architecture.

About Me

Passionate full-stack developer focused on simple, maintainable software

As a MERN Stack Developer with over 4 years of experience, I specialize in architecting robust web applications, real-time WebSockets engines, AI-powered assistants, and enterprise solutions.

Over the years, I've built products including multiplayer gaming platforms, QR-based discount checkout engines, agriculture expo management systems, and poster creation apps with KafkaJS microservices.

I strongly believe that maintainability is more important than writing clever code. Simple, readable, and consistent software wins.
