Senior🎓
Top SchoolErny Derksen is a Senior Software Engineer and architect with 13+ years designing and implementing open standards and open source solutions for e-Government and public-sector workflows. He specializes in Python and Django, BPMN-based process automation (Activiti/Flowable), document management (Alfresco), and identity federation (SAML2/CONFíA) while blending SOA/REST integration patterns and pragmatic, hands-on engineering. As a founder and former CTO of NextBPM and long-time TangramBPM architect, he has led product architecture, micro-ERP builds and complex integrations across Liferay, WSO2 and ESB platforms. He brings deep domain knowledge of Spanish public-sector regulations (ENI/ENS) and digital signatures (XAdES/CAdES/PAdES) that make his solutions auditable and interoperable. Comfortable from low-level OpenSSL tooling to FastAPI async services and OpenAPI design, he pairs rigorous standards expertise with practical delivery in Agile teams. Based in Seville, he quietly combines enterprise-grade architecture skills with decades of small-organization CTO experience, making him effective at both strategy and hands-on implementation.
