Over Gerrit
With over 20 years of experience in highly regulated sectors like Healthcare and Finance, I specialize in transforming complex business requirements into secure, production-grade digital solutions. My focus is always on the problem at hand, using technology as a lever to create reliability, security, and efficiency.
What I bring to the table:
- Strategic Problem Solving: Whether it’s modernizing a legacy monolith or designing a cloud-native architecture, I prioritize business continuity and long-term maintainability.
- Security by Design: Deep expertise in building applications that meet strict compliance standards (ISO 27001/13485), including robust identity management (OAuth2/JWT/OIDC) and data protection.
- Pragmatic Innovation: I integrate modern technologies like Generative AI not because they are trendy, but where they offer tangible value in automating complex workflows or enhancing data processing.
- End-to-End Ownership: Hands-on expertise in Java/Spring Boot and AWS infrastructure automation (CDK/Terraform).
I’m looking for assignments where my expertise in the Java ecosystem, modern frontend frameworks, and AWS infrastructure can provide the most leverage. I specialize in delivering end-to-end, production-grade solutions, from responsive Angular interfaces to secure, scalable backends, ideally for organizations that value long-term maintainability over quick-fix solutions.
