What I'm looking for

I seek a hands-on backend or cloud role where I can lead technical efforts, work with .NET and cloud platforms, mentor teammates, and build scalable, well-tested systems in a collaborative environment.

I am a backend-focused software engineer with extensive experience building scalable .NET services, cloud integrations, and mobile backends. I consistently deliver server-side solutions using .NET Core/NET 5/NET 8 and relational databases for production systems.

I've led small teams and acted as a team leader while contributing hands-on to projects spanning e-commerce, telemetry, and telecommunications. I design and implement integrations with AWS and Azure, payment providers, message brokers, and workflow engines.

My technical work includes real-time telemetry with QuestDB, distributed caching with Redis, messaging via NATS, containerization with Docker, and automation/testing using Selenium and Playwright. I also have front-end and mobile experience (React, React Native, Ionic) and have built end-to-end mobile solutions with backend synchronization.

I bring practical cross-functional experience in DevOps, testing automation, and system integrations, and I look for roles where I can both lead technical efforts and remain hands-on developing robust backend architectures.
