Technical lead for the Amsterdam Inspection Portal (AIP), a platform managing inspections and condition data for critical city infrastructure including bridges and quay walls.

Key contributions:
Led React/TypeScript/NestJS development on a codebase with significant technical debt and no initial test coverage. Designed and implemented refactors that reduced debt and increased development velocity.
Implemented GraphQL and REST services in NestJS with Prisma, including resolvers, schemas, DTOs, and validations.
Migrated the codebase to Nx monorepo, resolving circular dependencies and improving developer experience.
Built a new workflow application (React/NestJS), responsible for initial architecture and core implementation.
Developed a micro-frontend distributed as an NPM package, integrated across multiple applications.
Introduced feature-sliced architecture and AI-assisted development workflows using Copilot with custom context-engineering patterns.
Collaborated with UX designers, domain experts, and architects to model complex inspection processes and translate them into user-focused functionality.
Contributed to containerization (Docker/Compose) and Azure migration (App Insights, Blob Storage, Service Bus, AKS).
Regularly acted as release master, coordinating releases, tagging, and validation across teams.
Mentored team members on TypeScript, testing, and best practices while remaining hands-on in production code daily.
