Systems.

Designing scalable Java microservices, resilient cloud platforms, and enterprise applications that power real-world businesses.

About

I build backend systems that are reliable, scalable, and designed for long-term maintainability. Over the past six years, I've worked on enterprise platforms, cloud migrations, distributed microservices, and performance optimization using Java, Spring Boot, Kafka, Redis, Docker, Kubernetes, AWS, and integrating Gen AI and Agentic AI workflows. I enjoy solving complex architectural problems, improving system resilience, and designing APIs that remain dependable under real production workloads.
