Work experience

Data analyst

from 05.2024 to 09.2025 (1 year 5 months)
Датагруп, Volia, Київ (Телекомунікації, зв'язок)

Technologies: MSSQL, Power Bi, Excel, Google Analytics 4, Looker Studio
Was responsible for collecting raw data from company's database and interpreting it into simple, understandable formats. This meant building new and maintaining old reports and making them work as efficiently as possible. Thanks to my expertise, older reports were optimized to work up to two times faster and automations, made to existing reports and data-collecting techniques, allowed for redirecting efforts of the department into more important matters, making the whole reporting system self-sustainable.

Software engineer

from 07.2019 to 07.2023 (4 years)
Adelina Call Center & BPO, Київ (Телекомунікації, зв'язок)

Technologies: Embarcadero Delphi XE, DevExpress tools, Tortoise SVN, MSSQL, .Net Framework, JS + Node
I was engaged in a wide range of tasks: supporting the project's old code base, modernizing and refactoring it, improving architecture, creatiing new functionality according to the client's requirements, managing company's MSSQL database. Created software for mail services that optimized company's work - that allowed to save working hours of at least dozen of people every week.
While most of company's projects were build using Delphi, in-built software and software for domestic use came in a variety of different technologies, including JS + Node, which allowed me to try my skills in it.
