👋 Hi, I’m Sumit Roy

🎓 Computer Science Graduate
💻 Backend / Platform Engineer
☁️ DevOps • Cloud • Infrastructure

I’m a backend-focused software engineer with strong hands-on experience in building, containerizing, and deploying real-world applications. I enjoy taking projects end to end — from backend design and APIs to Docker, Kubernetes, CI/CD, and cloud deployment.

I focus on clean architecture, scalability, and production-ready systems, not just writing code that works.
