Data Scientist (Master Thesis) at Metso Frankfurt, Germany

Developed a production-ready anomaly detection framework for multivariate industrial time-series data, evaluating Static-PCA, Adaptive-PCA, and a Graph Deviation Network (GNN) to improve predictive maintenance and process monitoring. Built reusable Python data preprocessing and feature engineering pipelines for 5+ years of sensor data, reducing data preparation time by 30% and enabling reproducible model development. Engineered Dockerized Python services with gRPC, CI/CD, Azure, Git, and comprehensive unit/integration tests to improve reliability and maintainability. Designed and deployed a root-cause diagnostic Grafana dashboard for real-time equipment monitoring to enable proactive anomaly detection by process engineers.

Built a real-time process monitoring system for 100+ process sensors. Benchmarked statistical outlier detectors (Isolation Forest, LOF) alongside time-series forecasting models (ARIMA, SARIMA, Prophet, LSTM) for drift detection and predictive maintenance on live plant data. Automated preprocessing, feature engineering, and exploratory analysis pipelines for high-dimensional time-series data and collaborated with process engineers to validate models using domain expertise.

Connected ACT process control software with gRPC and built a Grafana KPI dashboard combining domain-informed process health metrics with linear regression on sensor trends to detect early signs of degradation for predictive maintenance. Collaborated with cross-functional teams to diagnose data-quality issues, define data-wrangling standards, and establish KPIs and validation criteria for downstream analytics.

Data Analyst at Dreamwarez

Built and maintained executive BI dashboards with DAX-based KPIs pulling together messy multi-source operational data into a unified decision-support layer for senior stakeholders. Shipped a Hospitality Revenue Analytics Platform for an e-commerce hotel client tracking RevPAR, GOPPAR, ADR, and Direct Booking Ratio to support dynamic pricing and daily operational decisions. Built end-to-end data transformation pipelines in Python, SQL, and statistics across scraping, ingestion, cleaning, transformation, and EDA for multiple business domains.
