Work Experience

Full Stack Data Scientist at International University of Applied Sciences

January 1, 2024 - Present

Led a cloud-migration and redesign of ML infrastructure from AWS to GCP, implementing a Vertex AI ecosystem with Kubeflow Pipelines, Feature Store, and 2-step Bayesian optimization for model training. Built batch prediction jobs, enabled CI/CD/CT with GitLab, and automated drift-detection alerts to productionize a XGBoost Lead-to-Customer model. Implemented automated monthly reporting using OpenAI LLMs and LangChain orchestration to generate stakeholder-ready insights. Also led customer churn prediction initiatives for the Sales department by leveraging the updated Vertex AI pipelines and feature platform.

Data Scientist at IKEA

January 1, 2022 - December 31, 2024

Developed waiting time prediction model and deployed to production using CI/CD (GitHub Actions), Vertex AI Kubeflow Pipelines, Firestore (NoSQL), and Google Cloud Functions. Designed HTTPS-triggered preprocessing, prediction, and postprocessing; data stored in Firestore via training pipelines and Pub/Sub triggered functions for inference. Built time-series forecasting with LightGBM to predict daily store transactions up to 14 days ahead; led guidelines and templates for structuring code and deploying models with Vertex AI/Kubeflow pipelines. Retrained a BERT-based text classifier for multiclass classification and performed embedding-based clustering with HDBSCAN to extract topics.
