Work Experience
Tech Lead, Data & AI | Machine Learning Expert
Capgemini
- Architected the global technical roadmap for an AI-based budgeting platform for a leader in the automotive industry, aligning machine learning requirements with scalable architecture and delivery milestones.
- Managed the end-to-end AI budgeting platform for an automotive giant. Used Dataiku to engineer forecasting pipelines and clustering algorithms that segmented financial behaviors, reducing budgeting lead time by around 30%.
- Led the development of a scalable attrition prediction engine for a top HR department using Azure ML. Engineered behavioral features to anticipate workforce risks, successfully deploying the solution across multiple business scopes.
- Directed a POC formaterial slab positioning, employing advanced combinatorial optimization techniques to minimize waste and enhance operational efficiency—a methodology transferable to squad rotation and resource allocation problems.
- Supervised a cross-functional squad of data scientists and data engineers, enforcing best practices in software quality, modularity, and system maintainability.
- Defined the integration and testing strategy, including unit and integration tests for critical financial transformations, to ensure the reliability of the industrial solution.
Senior Data Scientist
Capgemini
- Led a technical POC automating legal text changes for a government agency. Deployed Natural Language Processing (NLP) models to parse documents, accelerating processing speed and saving 40% of agent time.
- Built and deployed a risk-anticipation tool using time-series analysis to detect "weak signals" and anomalies in operational data, enabling proactive intervention before critical failures.
- Delivered a Web Scraping use case to aggregate external data for a fraud detection model, demonstrating strong capabilities in building unconventional data pipelines.
- Implemented a Named Entity Recognition (NER) solution to extract strategic insights from unstructured Request for Proposal (RFP) documents, automating the detection of new business opportunities.
Machine Learning Engineer | Volunteer
Self-employed
- Contributed to "Optimizing Lung Cancer Screening Protocols" (Journal of Thoracic Imaging, 2023), applying statistical rigor to false-positive rate analysis—demonstrating the ability to apply data science to biological/ human performance contexts.
- Collaborated with a cardiologist on predictive modeling of clinical data for early risk detection and outcome classification.
- Explored other medical and AI projects, focusing on the intersection of predictive modeling, data governance, and applied healthcare analytics.
Solution Implementation Lead
Murex
- Steered technical delivery streams for complex risk and reporting systems for major EMEA banking clients, managing the project from initial scoping to final go-live.
- Acted as the primary technical liaison between product owners and developers, translating complex regulatory requirements into scalable architectural features.
- Optimized SQL-based workflows and analyzed high-volume data flows to ensure seamless integration between trading, risk, and finance modules.
