RELEVANT EXPERIENCE

Started as a freelancer – created APIs and implemented business logic on the backend side, worked with third-party APIs.

After that worked at ProFix (banking field):
- as a junior Java software engineer – fixed bugs and fails in logic. Also worked with SQL queries and reports (analytics)
- as a Java software engineer - created new features for clients (new business logic on the backend side), new API endpoints, native and Spring Data queries to DB (Oracle, Postgres plain selects, aggregations). Created DB updates - DDL. Sometimes created updates for the report list. Also, I have implemented integrations with third-party systems (via REST and SOAP). Worked as a mentor for new teammates.
In the Inmost (healthcare project) as a Java software engineer has participated in features development, worked with Spring Data queries, and improved performance for backend modules (profiling and refactoring for code-base). Created API endpoints (Rest). Managed and extended integration with CI app - Jenkins for microservices.
In the Digitally Inspired Ltd (retailing project) - worked on the microservices platform (more than 100 different ms) that working on AWS under EKS-service:
- worked both alone and in communication with technical architects, teamlead, and engineers from my and third-party teams (integrations, devOps, frontend, mobile);
- took a part in decisions call about new features, topology, solutions and other technical moments on the platform and team levels;
- took a part in new ms design and creation (full lifecycle from technical design, solving problems or disputed points and implementation to helm chart creation with CI/CD deployment on k8s and documentation);
- researched and fixed problems on production env (only that related to deployed ms, not infrastructure);
- additionally worked on POCs (proof of concept for new features, technologies, and approaches) - researching and MVP implementation for them (google drive opportunities researching, integration and first ms with DGS framework instead of graphql-java libs for example).

ENGLISH LEVEL - Intermediate.
