Summary
As a seasoned C# developer and technical lead, I have extensive experience designing, developing, and maintaining complex software applications. My core expertise lies in building scalable, high-performance backend solutions using microservices and event-driven architectures, ensuring modularity, flexibility, and long-term maintainability.
Throughout my career, I have worked across diverse industries—including automotive, gaming and content, energy, and medical—contributing both to the architectural vision and hands-on development of critical systems. In many projects, I played a key role in guiding technical decisions, establishing best practices, and supporting teams in delivering high-quality, reliable software.
While I have full-stack experience, my primary focus has always been backend engineering and distributed systems. I am proficient with technologies such as .NET Core, Entity Framework, Docker, Angular, and cloud services. Although I have worked with AWS, the majority of my cloud experience centers on Microsoft Azure, particularly in building, integrating, and deploying cloud-native solutions.
I am passionate about continuous learning, staying aligned with modern engineering practices, and helping teams grow and deliver exceptional software.
