About Sonja

I help companies make machine learning systems production-ready – from data pipelines to APIs.
My focus is on MLOps, model training, deployment, and scalable infrastructure (Docker, MLflow, Airflow).

I have practical experience with end-to-end projects like an e-commerce classification system (text + image), including data processing, feature engineering, model training, and deployment as an API.

I work in a structured, solution-oriented way and think like an engineer – not just a data scientist.

Typical projects:
• Building ML pipelines (training, evaluation, deployment)
• API development for models (FastAPI)
• Experiment tracking & model versioning (MLflow)
• Data processing & feature engineering

Goal: working systems, not just models.

    Bietigheim-Bissingen, Germany
    Development of a scalable machine learning system for automatic classification of e-commerce products (text + image) as part of an MLOps project.

    Building an end-to-end pipeline from data processing (approx. 100k datasets, text + image) through feature engineering and model training to deployment and API integration. Combination of NLP and computer vision approaches for multi-label classification.

    Implementation of experiment tracking and model versioning with MLflow, as well as building a containerized microservice architecture with Docker (training, API, data services). Use of MinIO as S3-compatible storage and integration of a database for structured data management.

    The goal was a reproducible, scalable, and production-like ML system, including an automated pipeline (Ingest → Train → Predict).
