Project 1: Developed a robust analytics system with MongoDB for finding crypto arbitrage opportunities, handling 1000+ spot trading WebSockets, and improved an arbitration system that increased monthly profitability by 20% on the back end. Improved UI and UX, created analytics dashboard on the front end side. Increased test coverage from 0% to 65% using Jest.

Project 2: For the second project, I took part in creating a decentralized exchange aggregator in the Telegram Web Application based on the TON blockchain, designed a user interface, implemented user analytics collection, and made most of the features from scratch on the front end side, integrated the back end, and was responsive for implementation of collection and processing of data from the blockchain and its subsequent storage in Redis.
