PROFESSIONAL EXPERIENCE
EPAM Systems - Trainee -> Junior -> Middle .NET Software Engineer November 2021 - Present

Delivered backend solutions for international clients in the entertainment, financial and life-sciences domains.
Focused on microservices development, performance optimization, cloud (Azure) integration and migration of
legacy systems to modern .NET.

Key achievements:

• Implemented Redis caching at the middleware and attribute level, noticeably reducing load on third-
party APIs and improving overall application response times.

• Optimized EF Core query execution and data access patterns, reducing query response time by ~12–15%.

• Designed and developed a new microservice from scratch, including DB schema, REST API and inter-
service communication (JSON/XML).

• Built event-driven workflows on Azure Functions using Service Bus and timer triggers, and implemented
the Orchestrator (Durable Functions) pattern; worked with Azure Blob Storage and App Configuration.

• Integrated services via message brokers — Azure Service Bus (primary) and RabbitMQ.

• Upgraded services to newer .NET versions, modernizing the codebase and reducing technical debt.
 • Authored SQL stored procedures and optimized complex queries for reporting and business logic.

• Extended React components and the backend–frontend data contract (mapping models, adjusting what
the UI consumes and the API returns).

• Built resilient HTTP clients (retries, logging) for internal services and external SOAP/REST APIs.

• Integrated AI tooling via MCP, creating custom skills aligned with project requirements.

• Authored unit tests (xUnit), conducted code reviews, mentored junior developers, and contributed to
CI/CD pipelines in Azure DevOps with Docker.
