What I'm looking for

I am looking for senior engineering roles focusing on scalable backend/cloud systems, fintech or AI-enabled products, cross-functional teams, technical leadership, and opportunities to grow influence on product and architecture.

Senior Software Engineer with over 15 years of experience across FinTech, Banking, Insurance, and Telecommunications sectors, specializing in scalable microservices, cloud and enterprise solutions with proven track records of enhancing systems performance and strict compliance.

My technical expertise spans Java, Spring Boot, Spring Framework, Web Development (Servlet, JSF 2.2+, JSP, JSTL, XHTML, CSS, Bootstrap, JavaScript), ORMs (EclipseLink, Hibernate, Spring Data JPA), SOAP/RESTful APIs, cloud platforms (AWS, GCP), containers (Docker, Kubernetes) and relational databases such as MySQL and PostgreSQL.

I continuously expand my skills in AI, machine learning, and prompt engineering while maintaining strong cross-functional collaboration, product delivery focus, and an emphasis on ethics and practical AI adoption. I seek to apply this blend of architecture, cloud, and emerging-AI experience to build robust, compliant, and innovative products.
