What I'm looking for

I'm looking to build secure, scalable cloud applications and modernize legacy systems, with hands-on work across .NET, Azure, AWS, CI/CD, infrastructure as code, APIs, and modern web front ends.

I've built and migrated payment gateway services at KPN N.V., moving legacy .NET applications toward cloud-native .NET 8/10 deployments on Linux and AWS while supporting secure, high-performance transaction processing.

I design REST APIs, JWT authentication, CQRS workflows with MediatR, and Vue.js single-page applications that decouple legacy Razor/MVC front ends. I also automate secure delivery through Azure DevOps YAML pipelines, Terraform, Ansible, Trivy, Chekov, KICS, and OWASP ZAP.

At Exact B.V. and ABB, I modernized .NET systems for ERP and global EV charger management, working with Azure services including Cosmos DB, Functions, Event Hub, Service Bus, App Service, and SQL.

My background also includes embedded C/C++, Android development, data analysis, Linux administration, and secure application testing. I enjoy adopting practical tools such as GitHub Copilot to improve development efficiency.
