If you can ship a React or Next.js app but freeze on DSA, system design, or mid-level interviews, this is the room.

ATO’s Dev Lab is a free practice community for engineers moving past tutorial CRUD toward the skills companies actually hire for: algorithms, system design, and how production software is built.

I am ATO. I build with React, Tailwind, and Next.js. I have failed interviews. I am studying the same things you are. I post the problems, notes, and live practice I am already doing for myself. You practice beside me. Nobody here is selling a job.

What you get:

• DSA and LeetCode practice paths
• System design notes and discussions
• Backend and mid-level engineering resources
• A private forum and chat to post attempts and get peer feedback
• Live coding when I sit down to practice (replays stay up)
• No webinar schedule. No 12-week course.

This is not a bootcamp, not a job program, and not beginner CRUD training. If you want someone to hold your hand into a role, skip this. If you want an honest practice lab while you get better, join.

Free to join. Leave anytime.
