       Summary
       
       As a Java Developer at AISA IT-Service, I contributed to the migration
       of St. Petersburg’s automated budget planning system from a legacy
       Microsoft Access-based platform to a modern infrastructure using
       Vaadin 23, Spring Boot 2.7, Java 17, and Microsoft SQL Server. By
       leveraging the Waterfall methodology and Git Flow, I played a role in
       migrating VBA forms to Vaadin and ensuring compatibility with
       Microsoft SQL Server stored procedures.
       
       I have earned multiple certifications, including Certified Vaadin
       Developer and Cloud.ru (ex. SberCloud). My technical expertise
       includes Docker, Linux, FidoNet (yes, it’s is alive), SCO UNIX,
       NetBSD’s pkgsrc, GS Labs’ StingrayTV (platform which used in
       Tricolor’s set-top-boxes - the most largest pay TV operator in
       Russia), Yandex Home with Alice (smart home platform by Yandex), and
       more. Passionate about bridging legacy systems with contemporary
       technologies, I am eager to explore opportunities that align with
       these goals.

       Junior Java Developer | Apr 2024 - Aug 2024 | Санкт-Петербург, Россия
       
       I participated in the migration of St. Petersburg’s automated budget
       planning system from a legacy Microsoft Access-based system to a new
       system based on Vaadin 23, Spring Boot 2.7, Java 17, and Microsoft SQL
       Server. As part of the project, I used the Waterfall methodology, with
       elements of Git Flow (each task in Jira has its own branch), migrated
       VBA forms to Vaadin, and fixed business logic errors to maintain
       compatibility with Microsoft SQL Server stored procedures.
