I am a senior software engineer with 14+ years designing and delivering scalable, cloud-native systems across e-commerce, healthcare, and enterprise platforms.

My achievements include leading large-scale migrations and real-time analytics platforms, developing ML-powered fraud detection and forecasting services, and implementing robust CI/CD and observability across hundreds of services. I collaborate closely with cross-functional teams to solve complex technical problems while maintaining security, compliance, and high availability.
