What I'm looking for

I’m looking for remote, hybrid, or on-site opportunities worldwide where I can design secure, event-driven integrations using WSO2 (EI/APIM/IS), Java Spring Boot, and AWS serverless—while partnering closely with clients on requirements and delivery.

I’m a Senior Integration Engineer with 5+ years of experience designing and delivering enterprise-grade, event-driven integration solutions across higher education, ERP, CRM, and LMS ecosystems. I’m specialized in the full WSO2 stack (EI, APIM, IS), Java Spring Boot, and AWS serverless architectures, with deep expertise integrating UK/EU university platforms like Canvas, Quercus/Ellucian, Tribal SITS, Celcat, and Semestry across multi-tenant environments.

In each engagement, I own the full delivery lifecycle—from requirements analysis and technical scoping to solution design, client workshops, and end-to-end integration delivery. I work directly with stakeholders to translate business needs into robust, maintainable integration architectures, and I’ve led secure REST/SOAP API design, serverless async pipelines (including DLQ-based retry isolation), and technical handover via documentation and runbooks.
