Day 8

Internal pitch #1 — Data Technology SVP

Conference call + live demo of the marketing / BD tool for the Data Technology Senior Vice President. She loved it — and decided to show it to the CEO and other SVPs. She also offered to find strong IT people to deploy it. First early recognition, and the start of the internal pitch story: get the tool in front of the COO and CEO and make it a company-wide tool (700-person company).

Internal pitch #2 — Direct Supervisor (Program Manager)

Showed the tool to my direct supervisor, a Program Manager. She liked it too — asked me to walk the Regional Team through how to use it, and connected me with a Marketing Regional Director so we can improve it together. She also said she would announce the tool at the company-wide leadership meeting the following week, giving it more visibility.

HEC-RAS

40–50 structures into the HEC-RAS model via Cursor agent

Used the Cursor AI agent to write roughly 40–50 structures' information directly into the HEC-RAS model. Model changes are now made through the LLM — no need to write programs by hand.

Invasive species vegetation classification from high-resolution drone imagery

Used existing AI models for invasive species vegetation classification from high-resolution drone imagery — results were very good. Work that used to require expensive software can now be done with AI models.

Connected the QGIS API — spatial analysis without ArcGIS Pro

Building on yesterday's invasive species vegetation classification from high-resolution drone imagery, connected the QGIS API. Spatial analysis and data cleaning are now really fast — no need to run spatial analysis tools in ArcGIS Pro. Just explain the process clearly, and Cursor handles it. The process, the skills, and the Python scripts it outputs are all very good.

Shared invasive species vegetation classification with the team

Shared yesterday's invasive species vegetation classification from high-resolution drone imagery — the method and initial results — with team members, to see their response, including whether to build training datasets in the future and whether to internally train models.
