About
With over 14 years of experience, I specialize in building and scaling mission-critical systems that handle the pressure of 10,000+ RPS and millions of daily users. My expertise lies at the intersection of .NET Core, Azure-native architecture, and Microservices.
Throughout my career—from fintech to health-tech—I’ve focused on turning technical debt into high-performance assets. Most recently, I’ve led initiatives that improved system throughput by 35% and reduced infrastructure overhead by 20%. As a former Chapter Lead, I don’t just write code; I mentor teams to embrace SOLID principles and architectural excellence.
Core Tech: .NET Core, C#, Azure, Angular, Microservices, Kubernetes, and SQL/NoSQL.
