Over the past year and a half, I've built over 5 standalone projects for the Farcaster ecosystem, a social protocol on OP Mainnet. These range from developer APIs to user-friendly frontends for smart contracts. The largest is Searchcaster, a free and open-source search engine that has served 75M API requests in the last 12 months and is used by some of the most popular apps that integrate Farcaster.
My projects have made it easier for dozens of developers to build applications (Searchcaster), dozens of artists to distribute their work (Fardrop), and tens of thousands of consumers to observe the network/take control of their decentralized social profiles (Searchcaster, Farcaster Network, fcstr.xyz, etc.). These tools are built to enhance the Farcaster ecosystem which is rooted in OP Mainnet.
