What I'm looking for

I am looking for remote roles where I can lead backend and cloud-native projects, improve system scalability and reliability, and mentor teams.

I am a Senior Full-Stack Developer with 14+ years designing, building, and operating distributed systems, specializing in backend-heavy solutions and scalable architectures.

I have deep expertise in Java and Spring Boot, and have improved API performance by about 65% in high-traffic production systems while optimizing data access patterns for platforms handling tens of millions of records.

My work includes designing event-driven, asynchronous processing pipelines, operating cloud-native services on AWS and Azure, and driving reliability, observability, and CI/CD practices for high-availability financial systems.

I seek remote roles where I can apply my experience in microservices, event-driven platforms, and performance optimization to deliver resilient, maintainable systems and mentor engineering teams.
