What I'm looking for

I seek backend or data-focused roles where I can build scalable microservices, mentor teams, and grow into AI/ML-driven engineering responsibilities in collaborative, product-focused environments.

I am a Java-focused software engineer with extensive experience building and stabilizing production-ready microservices and backend systems across finance, automotive, and enterprise projects.

I've contributed to platform stabilization, migrations (Spring Boot 2.5 → 3.x), and production readiness work using Kubernetes, Jenkins, and SonarQube while collaborating closely with decision makers and cross-functional teams.

My toolkit spans Java 8–17, Spring Boot, PostgreSQL, AWS, Terraform, Elasticsearch, and CI/CD pipelines; I also mentor and onboard new team members and produce thorough documentation to ensure maintainability.

Increasingly I explore data-focused and AI/ML areas—data cleaning, transformation, and RAG pipelines with vector databases—bringing pragmatic engineering judgment to backend, data pipelines, and emerging AI-driven solutions.
