About

Professional summary

I am a .NET Software Engineer with more than five years of experience building cloud-native systems, distributed architectures, and resilient microservices. I specialize in .NET 8, event-driven platforms, and high-scale solutions that support critical business operations.

I have designed and delivered systems using Microsoft Orleans, Azure Kubernetes, Azure Functions, and Kafka. My work has included platforms processing billions of monthly events, real-time risk engines, and message-driven services operating across global markets.

I am experienced in applying software engineering practices that improve reliability, performance, and delivery outcomes. I use event sourcing, microservices, automated testing, and test-driven development to create maintainable production systems.

I have also contributed to AI and natural-language-processing initiatives, including Azure Cognitive Services implementations for compliance-risk detection and market-sentiment analysis. I balance innovation with practical considerations around reliability, scalability, and operational readiness.

I enjoy leading technical initiatives and supporting engineering teams. I have mentored backend, frontend, and DevOps engineers, facilitated innovation sessions, and helped establish career-growth practices that enabled team members to progress into senior roles.
