What I'm looking for

I'm looking to build and support enterprise Java systems, particularly in insurance or other regulated, high-transaction environments, where I can contribute to microservices, integrations, production reliability, and mentoring developers.

I've built and supported the Holistic Insurance Platform at 2Cana Solutions, a multi-country system for policy administration, billing, and claims-adjacent reporting. I engineered Spring Boot microservices and REST APIs supporting 5,000+ monthly secure financial transactions, improving feature delivery speed by 25%.

I optimize Oracle PL/SQL processes, BI Publisher reporting, and legacy system architecture for insurance operations. My work improved system performance by 20%, reduced production bugs by 35%, and supported underwriting, billing, policy, and compliance workflows.

I also deliver enterprise training in Java, Spring Boot, microservices, and Generative AI at MasterGradeIT, while mentoring junior trainers and guiding modern backend development practices.
