Summary
👤
Senior🎓
Top SchoolMachiel Keizer-groeneveld is a pragmatic Machine Learning Engineer with 13 years of experience designing cloud-native, secure MLOps platforms that take models from experimentation to production. He blends deep hands-on skills in Databricks, MLflow, Azure AI Foundry, AWS Bedrock and serverless architectures with a strong product and delivery focus, repeatedly turning ML prototypes into measurable business impact. Machiel has led and scaled cross-functional teams, driven cultural shifts from maintenance to delivery, and re-architected high-traffic platforms like Zoover and Weeronline. Notable recent work includes building an agentic healthcare assistant on Azure and architecting flexible Databricks pipelines that enable algorithm swap-and-test workflows. He’s equally comfortable with low-level implementation (Python, CDK, BICEP) and high-level strategy, and quietly champions practical simplicity — preferring elegant, maintainable solutions to flashy complexity.
