Profile
Accounts assistant with five years of month-end reconciliation and management reporting in a fictional building-supplies distributor, moving into data analysis after 14 months of evening study in SQL, Power BI and statistics. Already automates the finance team's reporting: a SQL-based margin report replaced 11 linked spreadsheets, and a matching query finds supplier invoice mismatches once found by hand. Seeking a junior data analyst role where accuracy and clear reporting matter.
Experience
Accounts Assistant (Management Reporting) — Fictional Builders Merchants Group
June 2021 – present · Finance team of six; 14 branches; around 3,500 supplier invoices a month.
- Reconcile the sales ledger, stock movements and bank each month across 14 branches, resolving every variance above the finance manager's threshold before the close on working day five.
- Rebuilt the monthly branch margin report from 11 linked spreadsheets into one SQL query and a Power BI dashboard, cutting the build from two days to about three hours.
- Wrote a SQL query matching supplier invoices to purchase orders on quantity and price; it flagged 38 mismatched invoices in its first quarter that manual checks had passed.
- Present the monthly margin pack to the finance manager and three regional managers, explaining movements by branch and product group in plain language.
- Documented every report's source, refresh timing and owner in a shared register, so the team no longer depends on one person's spreadsheet.

Projects
- Household water use by region (own time, 2026): combined two open datasets of about 180,000 rows in SQL, cleaned inconsistent region codes and built a Power BI report on consumption trends; the write-up states the limits of the sampling.
- Branch margin model (work, 2025): the rebuild above, with a definition of gross margin agreed in writing with the finance manager.
- Supplier invoice matching (work, 2026): the query above, tested against 200 historic invoices to confirm it caught every known mismatch.
