Profile: https://flows.cv/gurjinder

Software Engineer | Backend • Full Stack • AI/LLM

I’m a Python-focused software engineer with hands-on experience evaluating outputs from Google’s Gemini LLM project. I build scalable backend and full-stack systems using Python, Django, FastAPI, React, and TypeScript — with a strong focus on clean architecture, REST APIs, and microservices.

I’ve developed and deployed microservices for trucking e-commerce platforms, optimized backend data flows with RabbitMQ, and built interactive React frontends with Redux Toolkit and TypeScript.

On the infrastructure side, I use Docker, GitLab CI/CD, and PostgreSQL/MongoDB to deploy robust, containerized applications. I also follow system design principles like domain-driven design and event sourcing to ensure maintainability and scale.

I thrive in collaborative teams where I can solve real-world problems, write clean code, and contribute to products with real user impact.

📫 Let’s connect — I’m open to full-time backend, AI, or full-stack opportunities!
