Summary
Data Science & AI student (BSc, Breda University of Applied Sciences, expected 2027), currently interning at NPEC / Utrecht University, where I build a low-cost computer-vision system that measures plant growth in climate chambers. I bring 15+ years in integrating systems, work with data and educating people. That background drives how I work: measured results, sustainable systems that can run without me, and solutions that fit real workflows.
Experiences
Primary developer, under the supervision of NPEC’s Phenomics Engineering Innovation Lead, of a low-cost, camera-based imaging system that automatically measures plant canopy area in climate growth chambers, from 3D-printed mounts to the web UI. It is built to be deployed across ~15 chamber rigs.
- Measurement you can trust: Designed a validation method on the principle “certainty is measured, never derived”. Per-slot accuracy is within ±1.3–2.7% of true area (p95), and every reading is stamped PASS / DRIFT / FAIL when the rig is moved or knocked.
- Edge AI & computer vision: FastSAM runs on a Hailo-8 accelerator to split and identify trays (98.7% correct over 2,112 trays). AprilTags track each tray’s identity, position and rotation. Leaf area is within −2.5% (mean) of flatbed-scan ground truth.
- Root-cause analysis: Traced a systematic centre-of-frame area error to the camera’s focus lens and confirmed it against a reference camera. Also caught printer-scaling and tag-size errors through physical measurement.
- Hardware & deployment: Raspberry Pi 5 with a 64MP camera, parametric OpenSCAD tag mounts, a bill of materials and installation guide, and Ansible provisioning for the rig fleet.
- Touchscreen web app: FastAPI + HTMX app for the chamber touchscreens, with a calibration wizard, focus lock, experiment start/stop/resume, and checksummed data export.
- Agentic development: Directed Claude Code agents as architect and code reviewer: 116 merged PRs, 430+ tests, and the test suite cut from 303 s to 12 s.
- Programming & Tools: Python, Power BI, Pandas, NumPy
- Machine Learning: Predictive modeling, Scikit-learn, data governance
- Deep Learning: Human-centered design, responsible & explainable AI
- Computer Vision & Edge AI: OpenCV, AprilTag metrology, on-device inference (Hailo-8)
- Math Foundations: Linear algebra, calculus
- Year 3: 20-week industry placement at NPEC (see above)

Projects
Certifications
Completed the Data Protection Officer Training Programme at Maastricht University, focusing on the practical application of the GDPR within organizations. The program provided a comprehensive overview of data protection law, compliance obligations, and the role of the DPO in monitoring, advising, and cooperating with supervisory authorities.
Coursework included case-based analysis of data breaches, DPIAs, and cross-border data transfers. Emphasis was placed on balancing legal, technical, and organizational measures to support accountability and privacy by design. The program also covered the latest European Data Protection Board guidance and the evolving regulatory landscape.
Completed Google Workspace Administrator Training, covering user and group management, organizational unit structure, security settings, and application configuration within the Google Admin Console. Gained hands-on experience in managing accounts, enforcing policies, and optimizing tools such as Gmail, Drive, and Classroom to support school-wide collaboration and compliance.
