01 / About

Who I Am

I'm a third-year Electronics and Telecommunication Engineering student who decided early on that the boundary between hardware and software is just a mindset. While my degree teaches me how signals travel through circuits, I spend my evenings building the systems that make those signals mean something.

I've contributed to production-grade Kubernetes tools like Headlamp — not as a newcomer learning the ropes, but as someone who reads the codebase, identifies real bugs, and ships fixes that get merged. I believe the best way to learn is to build things that actually work in the world.

When I'm not writing code, I'm solving algorithmic problems on LeetCode (400+ problems, Top 14% globally) or studying how distributed systems behave under pressure. My CGPA of 9.16 isn't just a number — it's proof that I don't choose between depth and breadth.

“I don't just write code that works. I write code worth reading.”

Things I've Built

Real systems with real data, deployed and working. Not just side projects — full applications with authentication, databases, APIs, and users.

Featured Project

Expense Tracker System

A production-ready full-stack expense management application where users can track income and expenses, visualize their financial data through interactive charts, and manage their money with confidence. Built with security and performance as first-class priorities — JWT authentication, bcrypt-hashed passwords, and optimized MongoDB queries with 15% reduced latency.

·Full MERN stack — MongoDB, Express, React, Node — end-to-end
·Chart.js visualizations for income vs. expense trends and category breakdowns
·Secure JWT + Bcrypt authentication protecting all financial data
·RESTful API architecture with optimized MongoDB queries (15% latency reduction)
·Responsive UI — works on mobile, tablet, and desktop

Second Brain

A full-stack knowledge management platform — your personal digital brain. Capture notes, ideas, bookmarks, and references. Access them from any device with real-time synchronization powered by Firebase and MongoDB. Designed for engineers who think fast and need their tools to keep up.

·Real-time cross-device sync using Firebase + MongoDB hybrid approach (40% consistency improvement)
·Note retrieval latency reduced by 30% through smart caching and query optimization
·Modular RESTful API architecture — easy to extend with new content types

StationeryX Backend

A robust backend system for a stationery inventory management platform. Handles product catalog management, order processing, and real-time stock tracking through a modular API architecture. Built to demonstrate clean separation of concerns, proper error handling, and scalable database design.

·Modular Node.js API supporting product management, orders, and inventory tracking
·Optimized MongoDB queries and indexing improved query performance by 25%
·Comprehensive input validation and error handling for production reliability

Contributing to the Ecosystem

Real contributions to real production projects. Not tutorial repos — actual Kubernetes-ecosystem tools used by engineers worldwide.

I don't just use open-source tools. I improve them.

Contributing to the Kubernetes ecosystem as a third-year undergraduate isn't something that happens by accident. It requires understanding complex codebases, navigating real CI pipelines, writing test coverage, and communicating clearly with maintainers across time zones.

Every PR I've merged represents hours of reading documentation, tracing bugs through unfamiliar code, and iterating based on reviewer feedback. It's the closest thing to a real engineering job — and I treat it that way.
