Seven projects, strongest first

Ordered by what they demonstrate about analytical judgement, not by date. Figures shown are the ones the projects actually produced.

01

Education Analytics Dashboard

An interactive dashboard analysing student performance, teacher effectiveness and resource allocation across four regional schools — built so a school administrator could see where to spend attention first, rather than reading four separate reports.

65.57% Average attendance across the four schools.

Mathematics 20% Science 14.71%
Subject failure rates, scaled 0–100% so the two are honestly comparable.

Designed the data model tracking attendance, subject-level failure rates and student–teacher ratios. Ran a correlational analysis of teacher experience against GPA, which showed a positive relationship and exposed performance disparities between regions. Delivered predictive GPA modelling and resource-optimisation recommendations.

  • Data modelling
  • KPI design
  • Correlational analysis

02

Credit Risk Prediction

A decision tree classifier predicting loan default on a heavily imbalanced real-world dataset. Overall accuracy is the easy number to move; the number that matters is whether you catch the bad-risk applicants you would otherwise approve.

Baseline 32% After tuning 65%
Recall on the ‘Bad Risk’ minority class, scaled 0–100%. Overall accuracy held at 70%.

Addressed class imbalance and model overfitting with hyperparameter tuning via grid search cross-validation and pre-pruning. Deliberately prioritised recall on the minority class over headline accuracy — doubling detection of the cases that carry the cost.

  • Class imbalance
  • scikit-learn

03

Microsoft × EDI Business Challenge

Two AI-driven products built against real social and governmental problems: Altruize, a donor–charity matching system designed to raise engagement and optimise fundraising, and consultUK, a government-backed generative AI platform for public consultation that compresses policy response time from months to immediate.

Presented to leaders from Microsoft, Mind, the National Trust, Oxfam and RNIB — and pitched consultUK at 10 Downing Street.

The analytical work was in the matching logic and in framing what "success" meant for each product before building anything: engagement and fundraising yield for Altruize, response latency and coverage for consultUK.

04

Traffic Management & Heart Disease Risk

Two pieces of work applying the full data science lifecycle. The first: an intelligent traffic management framework using computer vision models — YOLO and U-Net — for vehicle detection and classification, with a deployment strategy for real-world use. The second: a K-nearest-neighbours classifier predicting heart disease risk across a 303-record clinical dataset.

On the clinical model, performance came from hyperparameter tuning and feature scaling rather than from a more exotic algorithm — a small dataset punishes complexity, and the discipline was in recognising that.

  • YOLO
  • U-Net
  • K-nearest neighbours
  • Feature scaling

05

Cryptocurrency Price Prediction from On-Chain Data

A deep learning framework forecasting short-term price movement from combined on-chain and technical indicators — testing whether blockchain-native signals such as investor profitability ratios and liquidity flows add predictive value over price history alone.

Collected, synchronised and cleaned large-scale on-chain datasets from multiple blockchain analytics sources. Engineered and selected features from a literature review plus exploratory analysis, then trained and validated LSTM models against price-only baselines using standard forecasting metrics — the point being the comparison, not the headline forecast.

  • LSTM
  • Time-series
  • Feature engineering
  • TensorFlow / PyTorch
  • Pandas

06

Gym Management System

A fully functional gym management system built from scratch: use-case diagram, entity relationship model, then normalisation of that ERD to guarantee data integrity and remove redundancy.

99/100 Awarded for the database design and in-class presentation.

  • Oracle Apex
  • SQL
  • ERD & normalisation
  • Agile

07

Inventory Management Application

A stock management application applying OOP principles for modular, maintainable code: a menu-driven interface with input validation, buy / sell / reprice operations and total inventory valuation.

97/100 Awarded, with credit for exception handling and robustness under bad input.

  • Java
  • OOP
  • Data structures
  • Exception handling

Source repositories are not linked here yet — the published repos do not cleanly map onto this project list, and a link that goes to the wrong thing is worse than no link. Happy to walk through code on request.
