What I'm looking for

I seek a senior technical role where I can design scalable cloud-native systems, mentor teams, and drive architecture and delivery with strong emphasis on reliability, performance, and CI/CD.

I am a Lead Engineer with over 11 years of experience designing scalable Java and Spring Boot microservices and leading teams to deliver high-quality, cloud-native solutions.

I have driven measurable improvements — including a 49% batch performance gain and a 60% cryptographic performance boost through key rotation — while adopting TDD, clean architecture, and domain-driven design.

I architect resilient distributed systems using Docker, Kubernetes, AWS, Azure, Kafka, and RabbitMQ, and implement CI/CD, observability, and performance tuning to support high-availability production environments.

I mentor engineers, conduct code reviews, and align technical strategy with business goals to drive digital transformation and consistent sprint output improvements.
