Problem Solving
Turning Ideas Into Software
I am Kumar Sahil
Full-Stack Web Developer | Backend Engineer
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.

Some of my works
A quick showcase of four recent projects spanning developer tools, scalable systems, and polished interfaces.
Add Google and GitHub login to your Django REST API in minutes. Handles token verification, account linking/unlinking, and JWT tokens out of the box.
Production-ready TOTP two-factor authentication for Django and Django REST Framework with encrypted secret storage, QR enrollment, backup codes, and JWT support.
A modern product catalog and marketing website for a forged components manufacturer - fast, searchable, and built to work without any server.
From frontend interfaces to backend systems and automation workflows, I build solutions that are maintainable, performant, and designed for real-world usage.
You have an idea - I turn it into a working product. I handle everything: the backend logic, the database, the frontend your users interact with, and getting it live. You stay focused on your business while I take full ownership of the technical delivery, from first line of code to production.
First impressions happen in milliseconds. I build interfaces that load fast, work across all devices, and guide users toward the actions that matter to your business. Whether it's a customer-facing product or an internal tool, the experience is polished, intuitive, and purposeful.
The backend is where your business logic lives - pricing rules, user permissions, data processing, integrations. I build secure, well-structured systems that do exactly what your product needs today, and won't collapse when requirements grow tomorrow.
Every hour your team spends on repetitive manual work is an hour not spent growing the business. I identify the bottlenecks and build systems that handle them automatically - reliably, in the background, without anyone babysitting them.
Articles written by me
A quick collection of recent articles spanning software engineering, backend systems, and modern frontend experiences.
A deep-dive into why Astro outshines React for static portfolio sites - covering SEO, performance, bundle size, and the real cost of over-engineering.
Most developers think rate limiting blocks requests before they reach the server. It doesn't. Here's what rate limiting really does, why your API needs it, and how to think about it like a bouncer at the door.
A plain-English comparison of social login options for Django. See why django-social-auth-rest is the fastest and simplest way to add Google and GitHub login to a Django REST API.
Learn why TOTP-based 2FA is essential for modern Django apps and how django-totp makes it easy to add secure two-factor authentication without building it from scratch.
