Make every financial decision a milestone.

I design cloud-native BI architectures for banks, financial institutions and enterprise clients: semantic models and reporting built to survive scrutiny, handover, and time.

Your data should tell you where to go next.

I help finance and data leaders turn fragmented information into a decision-making engine. 15+ years across banking, financial services, gaming, logistics and manufacturing, most of it on reporting that has to survive an audit as well as a board meeting.

That means cloud-native architectures, automated reporting pipelines, governance frameworks, and Power BI solutions that actually get used. Client work sits behind NDAs, so the evidence is in the portfolio

What I do

From numbers to momentum.

Start a conversation
01 / ARCHITECTURE

BI architecture & automation

Scalable, cloud-native architectures built for performance and maintainability, from ingestion through to semantic layer, with manual Excel workflows replaced by auditable pipelines.

02 / POWER BI

Decision-ready reporting

Executive-grade dashboards that get adopted. Data modelling, DAX optimisation, and the training and change management that make teams actually use them.

03 / GOVERNANCE

Governance & assurance

Access controls, data quality standards and audit compliance built to meet regulatory requirements. Delivered Scrum-led, with structured UAT and full release governance.

Work you can open

Not screenshots of claims.

Client work sits behind NDAs, so here are seven things you can inspect end to end, each mapped to the kind of work I do. Five of them below; the rest are in the portfolio.

A Power BI report on EU bank capital from the EBA transparency exercise, showing the sector CET1 ratio against the average and median of banks, a quarterly trend of the sector ratio against the average of banks on a constant panel, CET1 ratios by bank size, and a table by country.
POWER BI · REGULATORY REPORTING

EU bank capital

Three years of the COREP and FINREP returns 129 EU banks file with their supervisors. The sector’s CET1 ratio is 16.2%; average the banks’ own ratios and you get 22.7% — every ratio recomputed from its components.

A Power BI report on five years of workforce data, showing headcount at period end, joiners, leavers, annualised turnover and the share leaving in year one, a line of month-end headcount peaking at the end of 2022, a year-by-year table with turnover rising to 62.8%, joiners and leavers by year, and a department table.
POWER BI · HR ANALYTICS

Workforce analytics

Five years of HR records: headcount, turnover, engagement and training. The HR system’s status field contradicts people’s own dates 1,146 times, and 44% of training spend sits against people who did not work there.

Power BI · TMDL · DAX · Data quality

Explore the data
A Power BI report on a retailer's delivery performance, showing shipped orders by shipping mode against the days each order actually took, what each mode promises and delivers, the late rate by month, and two ways of counting late orders.
POWER BI · RETAIL & SUPPLY CHAIN

Supply chain delivery

Three years of a retailer’s orders against the lead time each shipping mode promises. First Class is late on every order, and the mode that costs more delivers no faster — only the promise differs.
