MIT IT Stock Manager

Selected work

2025

MIT IT Stock Manager

An inventory management system built for real departmental audit work.

This system was built for the MIT IT department to improve stock tracking and annual audit accuracy. The focus was not just on building screens, but on making the workflow practical for the people who actually use it.

RTSVLR - Speed Violation Detection

A computer vision project for license plate recognition and speed violation detection.

This project combines computer vision, night-time image enhancement, and edge deployment ideas for traffic monitoring. It was designed around a practical detection pipeline rather than a single isolated model demo.

Events MeetUp App

Selected work

2024

Events MeetUp App

A cross-platform app for discovering, joining, and managing events.

Built as a mobile-first product with event discovery, recommendations, and interaction flows. The goal was to make the app feel useful and intuitive rather than just feature-heavy.

Current direction

Shipping systems that survive real usage.

What excites me most is turning big ideas into real user experiences. I enjoy building products from scratch, solving problems in simple ways, and growing step by step both as a developer and as a person. Beyond coding, I believe in consistency, learning in public, and improving every day. I like sharing my journey, experiences, and thoughts while connecting with people who also want to build, grow, and create meaningful things. Right now, I’m focused on building scalable mobile apps, improving my skills, and working towards creating products that can help millions of people someday.
