What I'm looking for

I seek roles building reliable, high-throughput microservices in cloud-native environments, with opportunities to lead TDD, mentor engineers, and influence architecture and CI/CD practices.

I am a senior software engineer experienced in building enterprise-grade systems with high reliability, throughput, and flexible microservices architectures. I bring over six years of hands-on SQL/RDB experience and extensive work with Spring Boot Java applications.

My background includes designing and maintaining systems that use relational and non-relational databases, queues, caches, and Keycloak security. I have driven TDD adoption across teams and contributed to architectural migrations, improving system resilience and developer confidence.

I have implemented and managed CI/CD pipelines, Amazon EKS clusters, Helm templates, and Kubernetes tooling while working in cloud environments like AWS. I’ve also mentored peers and participated in technical reviews to raise team capability.

Across roles I have adapted to diverse tech stacks—including Angular, Redis, RabbitMQ, Elixir/Phoenix, and Ruby on Rails—delivering measurable improvements in performance, indexing, and deployment stability.
