About Navjeet Kajal:

I’m a full-stack engineer passionate about building scalable web applications and distributed systems. I specialize in designing robust backend architectures using NestJS, RabbitMQ, Redis, and AWS, and complement them with performant, user-centric frontends built with React and Next.js.

I enjoy working on real-time data pipelines, Amazon Ads/SP-API integrations, and end-to-end analytics platforms—owning systems from API design and microservices to frontend experiences. I thrive on solving complex engineering problems and building fault-tolerant, scalable solutions that drive real business impact.
