Hi, I'm Vasu Gajjar
Backend Developer & Software Engineer
Backend developer specializing in building scalable microservices, distributed systems, and cloud architectures. Experienced in Node.js, TypeScript, NestJS, and Golang with a focus on performance, reliability, and clean code.
The Story
I specialize in backend development with Golang, Node.js, and TypeScript, building distributed systems and microservices that scale. I've architected multi-tenant SaaS healthcare platforms serving multiple clients with zero-downtime deployments, designed event-driven architectures with RabbitMQ and Kafka, and built CDC pipelines for asynchronous audit logging across production systems.
I've published Rapid-MQ, an NPM library simplifying RabbitMQ integration used by developers worldwide. I thrive on solving complex problems around data consistency, real-time communication, and system reliability. My solutions have handled production traffic at scale across healthcare, project management, and game hosting domains.
I believe in writing clean, maintainable code that solves real problems. I approach each challenge with a focus on performance and developer experience. I continuously explore new technologies and share knowledge through open-source contributions.
