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 (450+ problems, Top 14% globally) or studying how distributed systems behave under pressure. My CGPA of 9.21 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

File Encrypter / Decrypter

Built a C++17 CLI utility for recursive directory encryption using a producer-consumer task queue with POSIX fork() for parallel file processing; dual-binary architecture separates single-file and batch workflows for composable scripting.

·C++17 CLI tool with recursive directory encryption and producer-consumer task queue
·Parallel file processing using POSIX fork() and a dual-binary architecture for single-file and batch workflows
·Flexible key derivation supporting hex, decimal, and UTF-8 key material
·Applied RAII with smart pointers (`unique_ptr`) and move semantics to safely transfer file stream ownership across IO, Task, and ProcessManagement layers

URL Shortener API

Built a containerized REST API in Go (Fiber + Redis) with custom alias support, domain validation, and UUID-based short-code generation; achieved sub-10ms redirect latency via Redis O(1) key lookups with TTL-based expiry.

·Containerized Go REST API (Fiber) with Redis-backed storage and TTL-based expiry
·Custom alias support and domain validation with UUID-based short-code generation
·Per-IP rate limiting using a dedicated Redis database logically isolated from link storage

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

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.
