Timeline

2015

The Spark

Class 5: wrote my first HTML & CSS. It wasn’t pretty, but it lit the fuse. By Class 7, I was writing C++ and realizing logic could be art.

2018

Foundations

Class 9: learned proper web dev with pure HTML, CSS, and JavaScript. Built my first fun clones — a Spotify UI and later a fully functional Airbnb clone during COVID.

2020

First Real Builds

Deep dive into MERN. Shipped projects that weren’t just tutorials but actual apps. Fell in love with turning concepts into experiences.

2022

Freelance Hustle

Started on Upwork, delivering small gigs. Each bug fixed was a paycheck and a lesson. Built confidence through real clients, real deadlines.

2023

From Freelancer to Builder

Built todayeggrates.com from scratch — now past 34.2k clicks and 2K monthly users. Also developed kolkatachessacademy.com + a custom LMS, experimenting with React + PHP stacks outside the usual MERN path.

2024

Parallel Worlds

Coder, writer, rider. I’ve kept them separate, but they shape me. Writing since Class 8, riding since 14 — creativity and grit fuel my builds as much as code does.

2025

From Code to Companies

Joined a startup as a Senior Developer, building a generative-AI media platform and a creator marketplace. Owning backend and infrastructure, and the on-call that comes with it.
