About

I am a senior .NET developer with over 6 years of experience in developing and integrating complex enterprise solutions. I specialize in building scalable systems, optimizing business processes, and delivering robust integration architectures. My professional background includes: 1) Developing enterprise systems for large banks and government agencies. Implementing complex integrations using message queues (Kafka, Apache Artemis MQ, IBM MQ) and the Outbox pattern. 2) Supporting and implementing over 20 integration microservices. 3) Optimizing application performance using monitoring and telemetry tools (OpenTelemetry). 4) Developing and maintaining Oracle and PostgreSQL databases, including stored procedures, PL/SQL packages, and schema migrations (Liquibase, Flyway). Experience in optimizing long-running queries. 5) Implementing complex business logic, including digital signature workflows and GraphQL integrations. In addition to my technical expertise, I actively participate in knowledge sharing — presenting at internal meetings, helping teams adopt new technologies, and maintaining a clean and maintainable codebase. Tech stack: .NET, ASP.NET Core, Entity Framework, Dapper, SQL, Oracle, PostgreSQL, Kafka, NATS, RabbitMQ, Liquibase, Flyway, OpenTelemetry, GraphQL. I’m looking for projects where I can apply my skills to build highly reliable systems and continue to grow in software architecture and distributed systems design. I’d be happy to discuss new opportunities!
