Experience
Data & Systems Analyst
Build and maintain the Power BI models and dashboards tracking critical operations and KPIs, with DAX measures and a dedicated date table, giving the executive team direct visibility into performance.. Work with operations, security and administration to understand what each area actually needs to measure, define the metrics with them, and take the dashboard through to adoption.. Own data quality across the reporting chain: deduplication on record identifier to prevent double-counting, reconciliation against source systems, and volume thresholds that raise an alert for review instead of processing when pending records fall outside the expected range.. Designed the data model behind a production system — 4 related entities, ~60 fields, 17 case types — and restructured a four-level location hierarchy from flat columns into a 117-record catalog as single source of truth, replacing hardcoded validation with data-driven filtering and letting the system scale to 8 branches without new development.. Built the automated pipelines feeding the reports over Excel and SharePoint sources, handling OData filtering, pagination past the 5,000-row threshold, date-serial conversion and status write-back.. Version-control the semantic models in Git using PBIP format, so model changes are reviewed as code and drift between specification and applied state is caught by diff.
Co-Founder & Data Consultant
Build reporting and tracking models for clients across finance, retail and logistics, including a live dashboard for a currency exchange desk covering balances by currency and client and spread calculation.. Designed a financial management model with live FX rate ingestion via API and per-record frozen historical rates, so restated reports reproduce the exchange rate in force at transaction date rather than today's.. Run several client accounts in parallel as the single point of contact: requirements, build, delivery and training.
Lecturer, Artificial Intelligence
Teach the Artificial Intelligence course in the Digital Business degree. Explaining technical findings to an audience with no technical background is the core of the job, and it transfers directly to presenting analysis to stakeholders.
Scrum Master
Led ERP data migrations across client accounts (Odoo on PostgreSQL), mapping source structures to target schemas and validating financial and operational data after cutover.. Coordinated cross-functional teams under Scrum and Kanban, acting as the interface between client stakeholders and the delivery team.
