Projects & Analytical Products
A comprehensive portfolio of interactive analytical applications, statistical methodologies, FinTech calculators, healthcare quality intelligence, and digital products built to solve real organisational challenges.
UK AI Economic Measurement Lab
An independent statistical research prototype and lab exploring the challenges of identifying, classifying, and disaggregating AI-related economic activity within UK National Accounts and Supply & Use frameworks.
- Supply & Use Explorer with 23 AI-relevant CPA product groups and SUT balance matrices
- Disaggregation scenario engines with parameter sensitivity curves and SNA asset boundary wizard
- Rule-based and ML classifier identifying AI vs. non-AI business economic activities
- Aligned with ONS Thematic Account Roadmap principles as an independent research prototype
Analytical Case Study & Methodology
Problem / Context: Traditional National Accounts frameworks and standard industrial classifications (SIC/CPA) do not isolate AI as an independent product group, complicating transparent measurement of AI production, intermediate consumption, capital formation, and trade across the UK economy.
My Contribution: Designed and engineered an independent statistical research prototype and interactive lab exploring supply-use disaggregation, activity classification, and asset boundary decisions.
Methods & Tools: Supply & Use Table (SUT) matrix analysis across 23 AI-relevant CPA categories; sensitivity scenario modelling for disaggregation parameters; rule-based and ML classifier identifying AI-related economic activities aligned with SNA 2008 / ESA 2010 principles.
Functionality: Features an interactive SUT balance explorer, asset capitalisation decision tree, parameter sensitivity simulator, and enterprise activity classification sandbox.
Limitations & Guardrails: Research prototype utilising published aggregate Blue Book benchmarks; broad product totals serve as candidate denominators rather than official estimates of AI output; requires explicit scenario assumptions.
Price Quality Explorer
An interactive Python and Streamlit analytical application demonstrating a structured, reproducible approach to price-data quality assessment and elementary price-index construction.
- Automated data-quality checks, anomaly detection & scale-error identification
- Zero/unavailable observation handling with audit trail and original data preservation
- Matched-item price comparisons with Jevons geometric index, Carli & Dutot comparators
- Year-on-year, category-level and seasonality exploration with sensitivity analysis
Analytical Case Study & Methodology
Problem / Context: Raw price collection data frequently contains scale anomalies, missing or zero values, item substitution gaps, and seasonal collection irregularities that distort consumer and producer price index calculations if not systematically audited.
My Contribution: Developed an interactive analytical application providing automated data quality auditing, scale error identification, and reproducible elementary price-index construction.
Methods & Tools: Elementary price index calculation comparing Jevons geometric mean, Carli arithmetic mean, and Dutot ratio-of-averages; automated distribution auditing; anomaly flagging; seasonality decomposition.
Functionality: Interactive dataset upload or pre-loaded retail price series; automated outlier and scale diagnostic panels; matched-item index comparisons with full audit trails and formula documentation.
Limitations & Guardrails: Demonstrator focused on elementary aggregate index levels; does not compute higher-level weighted Laspeyres/Törnqvist aggregations without expenditure weight datasets.
Performance Insight Explorer
An interactive analytical application transforming operational and organisational data into executive KPIs, trend analyses, comparative benchmarks, and evidence to guide strategic decisions.
- KPI monitoring, operational trend analysis and comparative performance reporting
- Upload-driven analysis and automated analytical workflows for fast insight generation
- Data-quality assessment integrated directly into decision-support dashboards
- Interactive visualisations structured for management and executive reporting
Analytical Case Study & Methodology
Problem / Context: Operational and departmental performance metrics are often trapped in fragmented spreadsheets, making it difficult for management to evaluate cross-unit efficiency, benchmark KPIs, detect anomalies, or identify root causes of performance variance.
My Contribution: Architected and built an end-to-end 14-stage diagnostic platform and decision-support system that converts raw operational datasets into executive intelligence.
Methods & Tools: Integrated statistical KPI benchmarking, distribution percentile profiling, time-series variance analysis, column mapping heuristics, and reproducible data validation pipelines.
Functionality: Interactive dataset uploading, automated data health profiling, multidimensional trend analysis, unit-by-unit comparative rankings, root-cause diagnostic views, and exportable findings summaries.
Limitations & Guardrails: Configured for tabular operational datasets; optimal performance requires clean time-stamped records and consistent categorical identifiers across reporting units.
