What I'm looking for

I seek a role driving backend architecture and cloud-native data solutions, mentoring teams, and delivering scalable, production-grade systems with strong CI/CD and automation practices.

I am a senior software engineer with over 10 years of experience building backend systems, microservices, and web applications using Java and related ecosystems. I focus on robust architecture, SOLID/OOP practices, and pragmatic design patterns to deliver maintainable solutions.

I've led teams and coordinated with cross-functional groups while working on engineering maintenance management, reservation/data-collection systems, asset management, and core-banking projects. I have hands-on experience in cloud data pipelines (GCP), infrastructure as code (Terraform), and CI/CD automation with Jenkins.

My technical breadth includes Java, Spring Boot, Scala (Play), Go, Node+TypeScript, databases (Postgres, SQL Server, Oracle), search/analytics (Elastic/Kibana), and reporting tools (Pentaho, Jasper). I also implement integrations using message brokers, service discovery, and caching layers in production systems.

I seek opportunities where I can drive backend architecture, mentor engineers, and deliver scalable cloud-native solutions that support data engineering and business-critical operations.
