At Slavyanbank, I designed and built a credit-department module for the “Inversiya” core banking system, replacing manual document preparation with a validated input form. The change cut the procedure from around 30 minutes to under 10 and eliminated a common source of data-entry errors.
I also developed an internal JavaFX tool that consolidated a multi-step file collection, archiving, and delivery routine into one application. Working with PostgreSQL and Oracle, I designed schemas, optimised queries to improve performance by 30%, and troubleshot production data issues.
At ITMO University, I contributed to a map-routing microservice and built a service for generating and storing geo-points. Earlier, at Top Media, I worked on internal and client applications, tests, and client-facing websites. I’m also actively developing Nihongo Trainer, a Japanese-vocabulary learning application with spaced repetition.
