Russia | work@oldzoomer.ru | egor@sdf.org | 2:5015/519
I modernized the St. Petersburg budget planning system by transitioning it from Microsoft Access to a Java-based architecture using Vaadin 23. This process involved transforming legacy VBA forms, addressing critical business logic errors, and ensuring compatibility with Microsoft SQL Server stored procedures to enhance system reliability and efficiency.
Certified as a Vaadin 24 Developer and Cloud.ru specialist, I bring expertise in Java, Vaadin, and Linux to deliver scalable and efficient solutions with a focus on legacy system modernization.
