why this exists · the comeback
Coders {cookies}isn't a startup pitch. It's a comeback story built from a hard lesson and a simple belief: every developer deserves a fair, structured, free start.
In 2021, me and a few close friends started Coders. Thousands of students joined from across India for a 30-day non-stop building, learning and session marathon. We partnered with almost all the developer, designer and builder communities across Web2 and Web3, along with a few big partners. It became the first community in 2021 to bring together 10,000+ builders in a single week from all over India.
Some partner communities never delivered the goodies and swags they promised. Students started questioning everything, and the community I cared about took the hit. It hurt deeply.
I stepped back rather than let it become something hollow. But the goal never left me: build a better developer community, the open and honest way.
Coders {cookies} is that comeback. AI surfaces the raw material, but every roadmap is deeply researched and restructured for real, serious self-growth open source, free, for every student.
Honest promise: this is all AI-researched content, structured into a website to guide beginners and learners to improve every day and it's free for now. It looks simple, but it'll bring the best to the table. I'm still learning and building.
And if it gets stopped this time too, I will not stop at all.
I'll grind and start building from scratch again. My aim and vision is simple build for the community.
