What I'm looking for

I’m seeking a senior architecture role where I can design cloud-native systems, define technical standards and governance, and lead modernization across distributed platforms. I bring 15+ years of experience in .NET/Azure, microservices, and DevSecOps-by-design, and I’m looking for a position where I can drive long-term architecture vision and mentor engineering teams.

Principal Software & Cloud Architect specializing in distributed systems, event-driven design, and large-scale modernization. I build sustainable, resilient, and modular architectures that align long-term technical vision with concrete business outcomes.

I design and govern complex systems using Azure, Kubernetes, microservices, Clean Architecture, domain-driven design, event-driven patterns, and modern .NET. My work spans cloud migration, platform engineering, enterprise-level CI/CD, and architecture governance to ensure consistency, reliability, and security at scale.

With 12+ years across banking, biomedical, retail, and consultancy, I lead teams, raise engineering standards, and build frameworks that outlive projects — enabling organizations to grow, adapt, and operate with clarity. I excel in environments that value autonomy, high craftsmanship, and long-term architectural strategy.
