The web application is a real estate platform that offers powerful tools to brokers, agents, and consumers across the entire transaction life cycle including transaction management, agent commission tracking, reporting, and disbursements.

I maintained the current code, fixed different issues, and implemented new features like: * infinite-scroll for different lists of entities * deepened and expanded a quick search with the help of Elastic Search * rewrote from scratch common-used entities picker with a lot of additional functions (depending on * settings show particular types of entities, create them, remove from the list if they were picked etc) * created a payment system for the application and copied process of whole users' anonymized data *from different environments (for example from Prod to Dev) for testing and bug fixing.
