Work that ends with
a decision, not a deck

Data engineering

Nothing downstream works if the data arrives late, twice, or in three different formats. We design the plumbing: integration between the systems you already run, ETL that runs on a schedule instead of on somebody's laptop, migrations that do not lose history, and database design that will still make sense in three years.

• System integration and scheduled ETL
• Data migration and consolidation between platforms
• Database and warehouse design, including SQL Server and MySQL
• Data quality rules, reconciliation and exception reporting

Data visualisation

A dashboard is a piece of user interface, not a gallery of charts. We start from the decisions it has to support and work backwards — which means fewer visuals, clearer ones, and a report that gets opened on a Monday morning without anybody being reminded.

• Power BI reports, datasets and workspace structure
• Excel dashboards for teams not yet on Power BI
• Star-schema modelling so totals stay correct under any filter
• Scheduled refresh, gateways and row-level security

Data mining

When you suspect something is in there but cannot name it yet. We work through large datasets looking for the segments, sequences and relationships that repeat — and we show the working, so the finding can be argued with rather than simply believed.

• Customer and product segmentation
• Trend, seasonality and anomaly detection
• Basket and sequence analysis
• Plain-language write-ups your board can read

Data analysis

A specific question, properly answered. What changed last quarter, which branch is carrying the margin, why the write-offs moved, what a price change would actually do. Scoped tightly, delivered quickly, with the assumptions stated up front.

• Ad-hoc investigations with a defined question and deadline
• Month-end and management reporting packs
• Variance, cohort and profitability analysis
• Second opinions on numbers you have already been given

Training

The part that makes the rest stick. Scheduled Excel and Power BI classes at three levels, capped so nobody hides at the back — or run privately for your team using your own reports.
