Vos.
Transforming complex data into elegant solutions. I build intelligent systems at the intersection of machine learning, data engineering, and applied AI.
Crafting intelligence
from raw data.
I'm Jonas — a third-year Data Science & AI student at Breda University of Applied Sciences. I'm passionate about building intelligent systems that solve real-world problems — from computer vision pipelines to full-stack AI platforms.
Across 9+ projects I've worked with deep learning, NLP, reinforcement learning, computer vision, and full-stack development. I thrive at the intersection of research and engineering — turning raw data into deployable, impactful solutions.
Data Science & ML
Statistical modeling, deep learning, NLP, and computer vision. From BERTje to U-Net to reinforcement learning agents.
Data Engineering
ETL pipelines, REST APIs, Docker deployments, and cloud infrastructure on Azure. Building systems that scale.
AI Applications
Full-stack AI platforms — from LLM-powered recruitment tools to smart campus analytics. End-to-end from prototype to production.
Technical arsenal.
Selected work.
Smart Campus Analytics
Predictive analytics system forecasting campus occupancy at BUas. Time series ML models integrating data from cameras, WiFi, and scheduling systems. REST API with real-time endpoints feeding dashboards and automated staff planning.
ObjectivEye
AI-powered recruitment platform for Dutch businesses. Uses GPT-4o for bias detection in job postings, CV parsing, ESCO-based skill matching, and EU AI Act compliance. Includes an ML Judge framework with 80 test cases for systematic prompt evaluation.
Plant Root Analyzer
Deep learning image segmentation pipeline analyzing plant root images using a U-Net CNN. Features CLI, web interface, and REST API — deployed both on-premise and on Azure Container Apps with full CI/CD.
NPEC Computer Vision & Robotics
Computer vision + robotics pipeline for the Netherlands Plant Eco-phenotyping Centre. Root segmentation (F1: 0.85), root system architecture extraction, and reinforcement learning agents controlling a liquid handling robot.
Dutch Emotion Detection
NLP pipeline for Dutch language emotion classification. Transcribes video/audio via Whisper, classifies 7 emotions using fine-tuned BERTje/RoBERTa. Achieved 84.7% accuracy with SMOTE-balanced datasets.
