I am a backend-focused developer skilled in Python, Django, building scalable APIs and reliable web applications. Familiar with React and currently advancing backend expertise through DRF, Celery, and Redis for scalable, asynchronous systems.
About Me
A short introduction about who I am, what I work on, and how I approach learning and development.
My name is Kumar Sahil. I'm a backend-focused full-stack developer and BCA student. I build scalable and reliable web applications using Python and Django, with working knowledge of React for frontend integration.
My experience includes developing RESTful APIs and backend systems using Django and Flask. I work with SQL databases and use tools like Git, GitHub, and Docker to build and manage applications efficiently.
Currently, I am strengthening my backend expertise by learning Django REST Framework and exploring technologies such as Celery and Redis to build asynchronous, scalable, and production-ready systems.
I focus on writing clean, maintainable backend code and continuously improving through hands-on projects, structured learning, and a strong foundation in core computer science concepts.
