What I'm looking for

I seek senior technical lead or architect roles building enterprise portals and integrations, with opportunities to lead teams, modernize stacks, and deliver cloud-native, secure solutions.

I am a senior Java/J2EE engineer and Liferay technical lead with 15+ years of experience building enterprise portals, CMS and integrations using Liferay (5.x–7.4), Alfresco, Spring, Hibernate and RESTful services. I have led development and delivery for B2B commerce, government and banking portals, implemented SSO/SAML, payment and shipping integrations, and driven performance hardening and cloud deployments.

I focus on pragmatic engineering: designing modular OSGi modules, custom portlets and headless API integrations, automating CI/CD with Jenkins, and containerizing with Docker/Kubernetes. My work has included leading teams, end-to-end portal implementations, troubleshooting production issues, and applying security and data-retention best practices.
