About Sebastian

Mijn kracht ligt in het vertalen van Machine Learning prototypes naar schaalbare, productieklare systemen die daadwerkelijk operationele waarde leveren. Ik help organisaties bij het ontwerpen, integreren en deployen van AI-oplossingen binnen bestaande software- en bedrijfsprocessen, met een sterke focus op betrouwbaarheid, performance en maintainability.

Daarbij heb ik veel ervaring met het bouwen van end-to-end NLP- en document processing pipelines — van data extraction en modelontwikkeling tot infrastructuur, deployment en monitoring in productieomgevingen.

Mijn interesse ligt voornamelijk bij de ontwikkeling en productie-integratie van Machine Learning- en NLP-systemen. Ik werk graag aan projecten waarbij AI-oplossingen daadwerkelijk geïntegreerd worden in bestaande software en operationele workflows.

Inhoudelijk ligt mijn focus vooral op:
Retrieval-Augmented Generation (RAG)
Search systemen (term-based, embedding-based en/of hybride)
Topic Modelling
Named Entity Recognition (NER)
Document extraction & understanding
Text classification
Private-hosted LLM systemen
NLP-systemen binnen high-security en/of hardware-constrained omgevingen
MLOps, model monitoring, data drift detectie, experiment tracking en lifecycle management van productie ML-systemen

Daarnaast heb ik sterke interesse in projecten op het snijvlak van Machine Learning en Finance / RegTech. Met mijn achtergrond in zowel AI als Finance werk ik graag aan systemen rondom:

Automated Compliance
AML / KYC
Fraud Detection
Transaction Monitoring
Financial document processing
Risk scoring
Workflow automation binnen financiële instellingen

Tech Stack:
