What I'm looking for

I seek senior backend or platform roles where I can design scalable, high-availability systems, mentor engineers, and drive cloud-native modernization within cross-functional teams.

I am a Senior .NET Engineer with 5+ years designing and delivering scalable, highly available platforms using C#, .NET Core, microservices and cloud technologies. I have a strong track record mentoring teams, driving architectural modernization and delivering solutions with high reliability and uptime for large user bases.

My accomplishments include developing 200+ critical technical solutions, implementing microservices architectures and CI/CD practices, and increasing team productivity through architectural guidance and best practices. I work well in cross-functional, international teams and bring advanced English proficiency for effective collaboration.
