What I'm looking for

I’m looking to lead cloud-native solution architecture—driving modernization, scalability, and efficiency—while building resilient microservices and DevOps pipelines in teams that value strong engineering and measurable impact.

I’m a seasoned Principal Software Architect with 21 years of experience designing and delivering large-scale, cloud-native enterprise systems across Microsoft Azure and AWS. I specialize in .NET, C#, and distributed application architecture, with a strong track record of modernization, scalability, and efficiency for global organizations.

In recent roles, I’ve architected and implemented core modules for a pharmaceutical management solution and designed scalable cloud-based APIs using .NET Core and SQL. I also automated CI/CD with Azure pipelines, improving the release cycle time by 35%.

At Microsoft, I led architecture for the Purview cloud solution focused on enterprise-grade privacy compliance and developed event-driven microservices using Azure Event Hub, Key Vault, Functions, and React UI. Across my experience, I lead teams, define solution architecture, and implement robust DevOps, microservices, and event-driven designs to improve performance and reliability.
