What I do

Where I spend my days.

By day I'm a Software Engineer, building and maintaining web applications with React and Node.js and designing the databases behind them. Alongside that I take on freelance builds and personal projects — from Flutter mobile apps to a fleet-tracking platform wired to real GPS hardware.

• Web applications

  Scalable web apps with React and Node.js — developed, tested and maintained for performance, security and reliability, with SQL and NoSQL schemas and queries designed for the data behind them.

• Mobile apps

  Flutter apps for Android and iOS: Padhaku, a learning app for school students in Gujarat that is live on Google Play, and PaisaSplit, an expense-sharing app with on-device receipt scanning and UPI settle-up.

• Tracking & operations platforms

  TrackOwl connects Teltonika GPS trackers, through a self-hosted Traccar server, to a React and Node.js platform for live fleet maps, trips, fuel, maintenance and billing, with support for several client companies on one system.

• MERN-stack & Web3 builds

  MERN-stack projects end to end: NFT Bazaar, a decentralized NFT marketplace with Solidity; Travel Buddy, an Android booking app with an OpenAI chatbot; and Campus360, a student life cycle platform with real-time alumni chat.

Approach

How the work gets done.

I like work that turns an idea into something people actually use — in a browser, on a phone, or wired to a tracker in a truck.

• Bring ideas to life

  From a learning app on Google Play to live GPS tracking, I take projects from an idea to a working product.

• Work as a team

  Strong teamwork is part of how I build — with my team day to day and with clients on freelance projects.

• Keep exploring

  I actively explore new technologies to keep up with the industry — Flutter, Solidity, the OpenAI API and GPS hardware all show up in my projects, and I hold Microsoft's AI-900 certification.
