Who I am

Engineering with precision,
leading with purpose

I'm a full-stack Java engineer specialising in backend architecture, cloud-native infrastructure and DevOps practices. Over five years I've contributed to high-stakes projects in banking, automotive fleet management, and insurance — always with a focus on clean code, maintainable systems and team growth.

Beyond shipping features, I've led technical migrations, defined CI/CD standards on Azure DevOps and GitLab, and facilitated knowledge transfer workshops for cross-functional teams. I also teach Java and web development as a part-time instructor.
