What I'm looking for

I seek senior full-stack/cloud roles where I can lead architecture and delivery of secure, scalable cloud-native systems, mentor engineers, and drive DevOps and performance improvements.

I am a performance-focused .NET full-stack engineer with 19+ years building scalable enterprise applications across FinTech, aviation, education, and SaaS domains. I specialize in C#, ASP.NET Core, microservices, cloud platforms (Azure, AWS, GCP), and real-time data systems, and I drive digital transformation through automation, observability, and secure architectures.

Throughout my career I have led architecture and implementation of high-throughput systems, improved performance and reporting (typical gains 35–60%), and mentored teams on modern front-end frameworks (Angular, React, Blazor) and DevOps practices. I hold multiple Microsoft certifications and consistently deliver production-grade solutions with strong security, CI/CD, and infrastructure-as-code practices.
