About George

I am George,

I help organizations design and realize scalable cloud-native solutions on Microsoft Azure and .NET. As a Software Architect and Tech Lead, I combine a strong passion for architecture with extensive experience in technical leadership, modern software development, and DevOps.

What sets me apart is that I not only design architectures but also guide teams and remain actively involved in the technical execution. I primarily work on complex digital platforms, integrations, and business-critical applications where quality, security, scalability, and maintainability are central.

With over 10 years of experience, I help organizations translate business goals into future-proof solutions based on Azure, .NET, Domain-Driven Design, and cloud-native architecture principles.
