I want to start an AI + Web3 community for builders.
This will be a space for people to share killer use cases, AI agents/workflows, onchain apps, hackathons, grants, fellowships, jobs, global events and builder resources.
A place where builders actually help builders.
Comment “builder” if you want to join.

- Meet Ahmed Nizam Mohaideen
- built an app that got acquired by Google for ₹280–350 crore
- founder of Where Is My Train
- built it after facing train delays himself
- got frustrated waiting for updates
- poor internet connectivity
- there was no simple way to track trains
- then saw the problem
- millions travel by train daily in India
- but tracking was confusing & data-heavy
- He thought: “Why not build something that works without internet?”
- so he built Where Is My Train in 2015
- works offline using cell tower data
- fast, simple, and super reliable
- people started to love it
- it crossed 100 million downloads
- earned almost nothing in the early days
- just pure focus on solving the problem
- which led to Google acquiring it for ₹280–350 crore
Crazy how one simple idea and right execution can do miracles 🔥

Building in Web3 is 10% syntax and 90% consistency + patience. Realizing how much I still have to learn, but we keep shipping. 🏗️✨
Onward! 🛠️ #BuildOnChainlink #zkSync #Solidity

Just deployed a new donation contract on @zksync Era Testnet! 🚀 I integrated @chainlink Price Feeds to enforce a $5 USD minimum—keeping values accurate regardless of market volatility. 📉📈 This project was a huge reality check for my dev journey...
