At SoftServe, I optimized Hangfire background jobs and reduced average execution time from 1.5 hours to 20 minutes. I also worked on data orchestration and memory leakages, and fixed crashes related to scheduled jobs.
I supported a transition from local datacenters to cloud systems using database replications, with both application versions running in parallel during the transition. I also integrated backend services with AWS S3 and SQS, including communication between an AI agent and the API.
I own and support two microservices, implement features directly with the client, and develop backend services for creating and modifying Excel files with large datasets. My work has also included Snowflake, PostgreSQL, and SQL Server queries and stored procedures for analytics and reporting.
Earlier at SoftServe, I contributed to a finance and trading API for gold and silver buy/sell workflows, implementing end-to-end functionality within existing system flows. I also worked on the personal non-profit project Korshak Ultrasound, providing full support for a React project.
