Summary
A short introduction and overview of my background, skills, and experiences.
My name is Kumar Sahil . I'm a full-stack developer who feels most at home in the backend.
I build backend systems with Python and Django - focusing on clean APIs, scalable architecture, and code that's built to last. On the frontend, I work with TypeScript, React, and Astro to create fast, modern interfaces that remain simple and maintainable.
Currently learning AI engineering, system design, async task processing, and how to build APIs and backend systems that can handle real-world production workloads at scale.
I care about writing code that's clean, practical, and built to last - not just to impress.
