The Platform That Gets Frontend Developers Hired
Skills are self-reported everywhere. GitHub shows code. LinkedIn shows job titles. IOCombats is different.
We verify what you can actually build through real challenges, track your consistency with a Momentum Score, and give you a public profile that shows recruiters verified proof of work, not just claims.

Built by a Frontend Engineer, for Frontend Engineers
Hi, I am Ghazi Khan. I have been building web applications for over a decade. I started IOCombats because I kept seeing the same problem: talented frontend developers struggling to prove their skills to recruiters who rely on self-reported resumes and generic algorithm scores.
I built this platform solo, with one goal in mind: to give frontend engineers a space where they can practice consistently, build a track record that speaks for itself, and walk into interviews with real proof of what they can do.
IOCombats is not a big company product. Every feature is built because a developer asked for it or because I felt the gap in my own career. That is the level of care that goes into every challenge, every question, and every line of code on this platform.

Developers Are Noticing
Unprompted reactions from developers who put the questions to the test.
"I've been writing CSS for the better part of 7 years, and I cannot answer a substantial number of these questions. Here comes the imposter syndrome."

This is one of the best sets of interview questions I've ever come across.

I started my career as a full stack developer a year ago. Now, writing code is not enough for me, I need to learn system design as I'm developing architectures, not just code. This resource is great, I love it.
