Nitin Kumar — Backend-Focused Full Stack Developer

Who I Am.

I’m a final-year Computer Science student at GLA University and a backend-focused full-stack developer. I enjoy designing secure APIs, authentication systems, real-time features, and maintainable backend architectures.

My primary stack includes Node.js, Express.js, MongoDB, React, JavaScript, TypeScript, Java, SQL, JWT authentication, role-based authorization, Socket.IO, and Docker.

I focus on writing reusable code, reducing backend boilerplate, applying practical security practices, and converting product requirements into working applications.

How I Build.

Secure by Default

Authentication, authorization, validation, rate limiting, secure headers, centralized error handling, and safe API design should be considered from the beginning.

Architecture Before Features

Define modules, data flow, API boundaries, and reusable middleware before adding complex functionality.

Build Reusable Systems

Avoid duplicating authentication, validation, logging, and response patterns across projects. Convert repeatable patterns into reusable abstractions.

Ship, Test and Improve

Build a working version, test real flows, identify failures, and improve the implementation based on measurable results.
