Took part in maintaining the company's main product, banking software, for various banks worldwide. Modernized it by migrating logic from database procedures to Java microservices. Developed a service for receiving multicast data from the stock exchange, in a multithreading mode from multiple channels, with the exclusion of duplicate messages, control of omissions, and the implementation of other business logic. This allowed clients (banks) to provide an extended range of services Took part in maintaining the company's main product, banking software, for various banks worldwide.

Programmer

Developed the backend for a sports federation portal and an application for working with the database of a government electoral system. Implemented full-text search (by vectors) in the PostgreSQL database. Created an approximate search by multiple parameters using the similarity function based on trigrams in the database, with the ability to set arbitrary search accuracy. This simplified data entry by operators about users, user search, and error correction in a large amount of personal data. Additionally, I developed a functionality for mass creation of data records about clients based on uploaded data in text format, after passing quality control that was also done by me Show less
