This project by far has been the most time consuming, most lines of code, and most educational project I have undertaken as a software engineer. I wouldn’t consider myself a “Crypto Bro”, but I do love the ethos underlying crypto: decentralized and fair finance for all. Because of this I had met some cool people working in crypto and one of them reached out to me because he knew I was a software engineer. He had an idea of building a better trading platform on top of decentralized exchanges (DEXs) than the rest of the competition. He is an experienced trader and knew what people liked, disliked, and wanted from their decentralized trading platform. With this in mind we have been building Celerity: Solana Trading Platform.

We first started out with building a frontend for Discord, because nearly all platforms were Telegram or Web based, but Discord is the home for most of the crypto communities today. Once I completed that we have been working towards building a faster, more comprehensive web terminal using my underlying backend for the discord bot as the web terminals backend.
