Project history

AI and ML Engineer

Tech Consulting
Architected a production multi-agent system for commerce over the Model Context Protocol (MCP). Built citation-first RAG using cosine-similarity retrieval. Implemented responsible-AI guardrails with spaCy. Built two-stage demand forecasting using computer-vision car-park counts feeding XGBoost and Prophet. Developed sentiment analysis of discussion-platform comments using Naive Bayes, KNN, and GLMs.

Data Scientist III and ML Engineer

Charter Manufacturing
Built predictive models forecasting steel demand using Python, SQL, R and Tableau. Engineered a custom Grid Search cross-validation approach for time-series data. Delivered Tableau dashboards of production data and KPI trends with documented model architectures and retraining protocols.

Decision Scientist

Confie
Led identification, measurement and control of risks from business activities. Applied advanced analytical techniques to medium- and large-scale business problems. Translated findings into communication materials and visualisations for varied management levels.

Senior Data Scientist

First Help Financial LLC
Developed customer scorecard models for loan decisioning using ensembles and logistic regression. Integrated alternative data from LexisNexis and SentiLink for thin-file and unbanked borrowers. Wrote complex SQL to extract JSON and XML values. Ran segmentation with decision trees and k-means clustering; engineered ETL pipelines for scalable retraining.

Accountant

BPA & Associates
Prepared monthly, quarterly and annual GAAP financial statements. Processed multi-state payroll with accurate tax withholdings and compliance. Digitised client records with structured folders and automated naming; performed variance analysis advising owners on cost and profit improvement.

Senior Data Scientist

Healogics Inc.
Conducted statistical analyses in R for clinical trials and wound-care research. Performed a bias-detection and causal-inference study using propensity score matching. Integrated structured and unstructured EHR data for research analytics and built reproducible, auditable workflows.

Data Scientist

Travelers Insurance
Built risk-based premium pricing frameworks using GLMs, spline models and tree-based ensembles. Enriched models with external demographic, behavioural and credit-based data. Established evaluation frameworks including lift charts, ROC/AUC, gain curves and SHAP-based bias and fairness testing.

Junior Data Science Associate

NLP Logix LLC
Built predictive models in R and Python forecasting horse-racing outcomes with bet-sizing optimisation. Developed marketing spend allocation models and automated previously manual data-preparation and reporting workflows; visualised outputs and KPI trends in Tableau.
