What I'm looking for

I seek backend or technical lead roles in collaborative, regulated-finance environments where I can improve system performance, mentor teams, and drive reliable, secure delivery.

I am a Java backend engineer with over six years of experience delivering scalable, secure, high-performance enterprise applications across banking, insurance, and digital asset management.

I translate business requirements into clean, maintainable code and have driven measurable improvements — for example, increasing system efficiency by 10% through targeted code and performance optimizations.

I have experience across the full backend stack: Java (7–11), Spring Boot, REST APIs, SQL databases (Oracle, PostgreSQL, MySQL), CI/CD, and containerization tools such as Docker and Jenkins, and I frequently collaborate with cross-functional and regulatory teams.

I have progressed into technical leadership (promoted to Team Leader), mentor colleagues through documentation and onboarding, and seek to continue delivering reliable financial systems while growing my leadership and architecture responsibilities.
