About me

I am a Senior .NET Developer and Tech Lead with extensive experience in designing, developing, and optimizing backend systems for high-traffic applications. I specialize in C#, .NET (Core / 6 / 7 / 8), REST APIs, microservices, and database-driven systems. I have a strong background in SQL Server, PostgreSQL, and Oracle, with a particular focus on performance tuning, query optimization, indexing strategies, and scalable data architectures. I have led backend teams, reviewed code, designed system architectures, and built integrations between e-commerce platforms, payment systems, logistics providers, and internal enterprise systems. I enjoy solving complex performance issues, eliminating bottlenecks, and turning slow systems into reliable, efficient solutions. I work well both as a hands-on developer and as a technical leader who can translate business needs into clean, maintainable, and scalable software.

Due to non-compete agreements, I do not cooperate with companies in the Fashion industry.
