🚀 Launching CODTRAKR

Back in 2024, at the beginning of my second year, I became obsessed with Data Structures & Algorithms.

Most of my days were spent solving problems on LeetCode, CodeChef, and Codeforces while working through Striver A2Z, NeetCode, and CSES (especially Trees and DP).

The more problems I solved, the more I noticed a pattern.

I would solve a great problem, learn a new technique, and then completely forget about it a few weeks later.

Before contests or interviews, I often found myself searching through old submissions, bookmarks, screenshots, and random notes trying to remember:

• Which problems were actually important?

• What approach did I use?

• Which concepts needed revision?

There was no system.

So instead of looking for a solution, I decided to build one.

CODTRAKR started as a simple tool where I could save problem notes, mark important questions, and create a revision system for myself.

But as I continued building and using it every day, the project evolved.

I added coding platform statistics to track progress, AI-powered features to make learning easier, and tools that I personally wished existed during my DSA journey.

The first version was built with plain HTML, CSS, and JavaScript. Over time, I rebuilt it using React and continuously improved the backend architecture.

While building CODTRAKR, I also grew as a developer by learning and implementing:

• Authentication Systems
• Email OTP Verification
• REST APIs
• Database Design
• Rate Limiting

Looking back, CODTRAKR is more than just a project.

It started as a solution to my own learning problem and eventually became a product that reflects my journey from solving coding problems to building software that solves real problems.

Today, I genuinely enjoy seeing myself not just as a competitive programmer, but as a software developer who loves building, learning, and improving every day.

And this is only the beginning.
