About Mike Walsh
I'm a data analyst and developer who likes nothing better than a messy dataset and a clear question. Untangle Your Data is my independent practice.
What I do
I work across the whole path data travels: getting it out of spreadsheets, databases, and live feeds; cleaning and connecting it; analyzing and forecasting with it; and presenting it in reports, web dashboards, and maps. That range means I can follow a question from raw data all the way to a finished answer.
How I work
- Question first. Tools come after we agree on what you need to know.
- Honest about uncertainty. Forecasts come with ranges, and I'll tell you when the data can't support a conclusion.
- Built to hand off. Everything comes documented, so you're never dependent on me to keep it running.
- Plain English. No jargon in the deliverables unless your team speaks it.
Skills at a glance
Python, SQL, PostgreSQL, Excel with Power Query and Power Pivot, Power BI, stream processing with Kafka and Flink, Flask, HTML and CSS, ArcGIS, Leaflet, and Linux servers on AWS. Each area has its own page under services.
