Sofware Engineer | TypeScript, NestJS, Node.js & AWS | Building Scalable, Secure & Reliable Systems

About

I’m Jatan Dudeja, a Backend Engineer passionate about building scalable, secure, and high-performance systems using TypeScript, NestJS, Node.js, and AWS. Over the past few years, I’ve worked on architecting production-grade backends that emphasize clean code, fault tolerance, and real-world performance. My experience spans designing RESTful APIs, implementing JWT-based authentication and authorization, and building record-locking mechanisms to ensure data consistency in multi-user environments. I’ve integrated services like Google Workspace, Cloudinary, and Razorpay into full-stack ecosystems, handled AWS deployments using EC2, S3, and Nginx, and ensured smooth operations through PM2-based process management. I enjoy solving backend problems that blend engineering depth with product impact — from optimising database queries to refining API response times and scaling cloud infrastructure. I thrive in fast-paced startup teams where ownership and speed matter, and I’m currently diving deeper into system design, distributed architectures, and AI-powered backend automation. If you’re building something ambitious and need someone who can design, develop, and deploy a backend that’s clean, scalable, and dependable, let’s connect.
