• Tuned hyperparameters with GridSearchCV, achieving 80.6% accuracy with random forest and XGBoost.
• Created visual reports (bar plots, heatmaps, radar charts) to interpret model performance and churn drivers.
• Exported reusable pipelines and trained models with joblib for deployment.

• Lead developer of Prof. Valmed, the first LLM-powered medical device (utilising RAG on a medical corpus of 2.5M+ documents) to receive a CE certification.
• Designed and implemented cloud-native MLOps infrastructure for ENBW’s energy trading analytics division, enabling scalable deployment and monitoring of predictive models.
• Architected end-to-end testing and validation frameworks for AI/ML systems, ensuring quality, compliance, and robustness in critical and regulated applications.
• Conducted professional training on AI testing, EU regulatory frameworks, and quality assurance for production AI systems.

• Built a Databricks ETL pipeline to ingest and clean JSON book metadata from the OpenLibrary API.
• Transformed nested datasets using Python/PySpark and structured them into curated analytical tables.
• Loaded processed datasets into Snowflake to enable SQL based reporting and metadata analysis.

• Responsible for developing and implementing the Risk Management Policy and Plan, ensuring structured risk identification, assessment, and mitigation
• Conducted comprehensive risk assessments on material quantities, procurement schedules, and contractor performance to ensure accurate forecasting and prevent delays
• Developed and maintained a risk register covering technical, financial, safety, quality, and environmental risks with focus on quality assurance and quantity control
• Collaborated with engineering, procurement, and construction teams to identify deviations in material usage and construction standards, reducing rework incidents by 18% and achieving 10% savings on material costs
• Prepared monthly Risk Management Reports highlighting key risks such as supply chain disruptions, cost escalations, and regulatory compliance issues
