Your data exists. The clarity it should be creating does not... yet. That gap is what I close. Over 10 years and 50+ projects across finance, healthcare, retail, energy, and technology, I have built the SQL pipelines, Power BI dashboards, Tableau reports, and Python automation workflows that turn raw, disconnected data into reporting systems organisations actually use and trust. What that looks like in practice: → A finance team drowning in manual Excel files every month-end: replaced with 40 dashboards that refresh automatically overnight → A forecasting process built on guesswork: rebuilt with Python models accurate to within 10% of actual figures, used in live budgeting cycles → Data preparation eating 40% of the team's time: automated with ETL pipelines that freed the team for work that actually matters → A reporting cycle taking three days every month: cut to a single overnight refresh — no manual input required The technical stack: SQL (SQL Server, MySQL, PostgreSQL) — complex queries, joins, stored procedures, window functions Power BI — DAX, Power Query, Power Pivot, live data connections, executive dashboards Tableau — interactive reports, calculated fields, live and extract connections Python (Pandas, NumPy) — data cleaning, automation, ETL pipelines, forecasting models Microsoft Fabric & Azure — cloud data integration, pipeline architecture Excel (Advanced) — financial modelling, pivot tables, VBA, Power Query Salesforce CRM — data extraction and reporting integration Most clients come to me with one of three problems: 1. Their data is in the right place but not connected, clean, or visible. 2. They need a dashboard or report that shows what actually matters to decision-makers. 3. A manual process is consuming time it should not and needs automating. I also hold an MBA, an Associate PMP, and certifications from IBM, Google, and Harvard Business School, which means I understand the business reason behind what you need, not just the technical execution of it. If you have a data problem, send me a message describing it. Tell me what you are trying to see, what you are working with, and what is getting in the way. I respond within 24 hours and I will tell you honestly whether I can help and how.
