What I'm looking for

I’m looking to build reliable, high-performance distributed systems—especially microservices and real-time analytics. I want a collaborative engineering environment where I can improve platform performance and mentor others through technical design and code reviews.

I’m a Senior Software Engineer with 14+ years designing and building scalable full-stack apps using C#, Java, and Rust across cloud-based platforms.

I specialize in microservices architectures, high-performance backend systems, and modern web applications with .NET and Spring Boot, including event-driven services for real-time processing.

I’ve integrated AI-driven data processing—building Python ML pipelines into production services—and delivered measurable impact, including improving categorization accuracy by 36%.

I’m passionate about building reliable software, improving platform performance, and mentoring engineers through architecture discussions, code reviews, and technical design sessions in collaborative environments.
