EchoDEX

At EchoDEX, I worked on the core systems that powered trading on the Linea network. I built the backend services that handled swaps, liquidity data, wallet activity, and smart-contract interactions in real time. My work included designing the transaction pipeline, creating a stable RPC layer, adding caching for token and pool data, and improving the reliability of trade confirmations during heavy network activity. I also worked closely with the frontend and smart-contract teams to keep everything in sync, reduce latency, and make the trading experience feel smooth for users.
