I'm a Senior Statistician & Data Scientist with extensive experience in statistical modelling, analysis and report writing. I've excelled in B.Sc. (Hons) and Masters in Statistics and a PhD in Social Statistics and Demography. I am proficient in SPSS, Stata, and R, focusing on multilevel modelling and longitudinal data analysis. I've successfully led diverse projects, e.g. health surveys, quality-of-life assessments for cancer patients, and census data analysis. My expertise ensures high-quality results for freelance statistical analysis projects.

I build AI, forecasting, risk-modelling, and decision-support systems in Python for businesses that need reliable, explainable outputs rather than black-box prototypes. I help clients turn messy operational data, technical ideas, or research models into working dashboards, APIs, reports, and production-ready analytics pipelines. I am a PhD-trained applied mathematician and AI/data science specialist with 20+ years of modelling experience across machine learning, predictive analytics, quantitative modelling, simulation, operational analytics, and real-world decision-support systems. I can help with: • Predictive analytics and forecasting • Machine learning model development and validation • Python dashboards using Streamlit, Plotly, pandas, and NumPy • Risk scoring systems and decision-support tools • Quantitative finance and simulation models • Data cleaning, feature engineering, and pipeline design • AI/LLM-assisted analytical tools • Model benchmarking, testing, documentation, and handover Selected projects: 1. Heston Model Calibration Built a reproducible quantitative finance calibration framework for the Heston stochastic volatility model using Fourier pricing, constrained numerical optimisation, multi-start robustness checks, and diagnostic visualisations. 2. Probabilistic Renewable Dispatch Developed a Python decision-support system for renewable energy forecasting, uncertainty calibration, and risk-aware dispatch planning using probabilistic forecasts, conformal calibration, optimisation, Streamlit, and FastAPI. 3. Latent Performance Benchmarking Created a portfolio benchmarking framework using Fama-French-style models and stochastic frontier decomposition to separate systematic exposure, noise, and latent performance shortfall. 4. Sensor-Driven Risk Scoring System Built an industry time-series analytics pipeline combining environmental and occupancy signals to generate operational early-warning risk scores for decision support. My approach is structured and delivery-focused: • Clarify the objective, constraints, and success metrics • Audit and validate the available data • Build a reproducible modelling pipeline • Test assumptions and document limitations • Deliver clean code, clear outputs, and practical recommendations • Provide handover documentation so the solution is maintainable after delivery Clients receive robust models, readable code, clear documentation, and outputs that support real decisions — not just notebooks or isolated scripts.
