Built with React Native, TypeScript, Redux Toolkit and GraphQL/Apollo, tested with Jest. Worked remotely with product and design to ship features used daily by sales teams.

    Senior Software Engineer (.NET/Sitecore)

    Als Senior .NET/Sitecore Developer bij ABN AMRO Hypotheken werkte ik aan de migratie van Sitecore 10.4 naar het headless CMS Contentstack. Mijn rol: de bestaande Sitecore-solution afbouwen en opschonen, performanceproblemen oplossen en meedenken over de inrichting van Contentstack en de contentmigratiestrategie. Resultaat: een slanker en stabieler Sitecore-platform tijdens de overgangsfase en een solide basis voor de nieuwe headless, composable architectuur. AI-assisted development is een vast onderdeel van mijn werkwijze: ik zet AI-tools in voor o.a. code-analyse, refactoring, het schrijven van tests en het voorbereiden van user story refinements, en beoordeel de output net zo kritisch als een code review. Eerder werkte ik bij Goudse Verzekeringen aan de migratie van Sitecore XP naar XM Cloud (SitecoreAI).

    Senior IT-programmamanager | ERP, migraties & AI

    IT-projectdirecteur bij General Electric (2018-2024). Ik leidde de ERP-afsplitsingen achter de opsplitsing van GE in drie beursgenoteerde bedrijven: GE Healthcare (23 juridische entiteiten, 5 landen, deels van Oracle naar SAP) en GE Aviation (15+ entiteiten, 10 landen). Daarmee werden de spin-off van GE Healthcare (jan 2023) en de splitsing GE Aviation/GE Vernova (apr 2024) mogelijk. Rol: eindverantwoordelijk voor scope, budget, planning, risico’s, end-to-end testen en go/no-go. Ik stuurde internationale teams van projectmanagers en consultants aan, inclusief TCS, Genpact en HCL. Bij Project Revere Asia zette ik een volledige go-live om naar een MVP, met aanvullende controls in fase 2. Stack: Oracle EBS R12, Oracle Cloud/Fusion, SAP, Navision, Concur. Agile en hybride, PRINCE2 7, PMP. Recent: interim teamleider Ecert bij Kiwa (SaaS, 23 landen, Dynamics CE). Ik bouw eigen tools met Claude Code, dus AI zit in mijn aanpak, niet alleen in mijn PowerPoint.
