raft_heatmap QGIS plugin

  • Organization: San Diego River Park Foundation
  • Location: San Diego, CA
  • Date: December 2025 - March 2026
  • Overview: Plugin that streamlines custom heatmap generation for SDRPF River Assessment Field Team (RAFT) data. The plugin allows a user to select a CSV export from the RAFT program, filter data pins by category, and visualize pins as a heatmap. Ideal for generating maps of activity hotpots for presentations and as a starting point for further analysis. This project also serves as an example of QGIS plugin development for future RAFT interns.
Details:
  • Technology: Python, QGIS Plugin templater, QML, PyQt, Sphinx
  • See the Project Documentation for additional installation, usage, and development information

RAFT Data Analysis Automation

  • Organization: San Diego River Park Foundation
  • Location: San Diego, CA
  • Date: December 2025 - March 2026
  • Overview: The data analysis portion of my GIS Data and Field Internship involved several manual spreadsheet steps and a data join in QGIS. Once I got the hang of the manual process, I decided to automate the manual steps with Python. Although there is not impetus to integrate automation into this workflow at this time for this internship, I found it to be a useful exercise in applying my software skills to a common data problem.

Senior Software Engineer

  • Organization: Various
  • Location: U.S.: Coast to Coast
  • Date: Prior to 2025
  • Overview: In my previous career, I worked across industries, growing my skill set until I became a full-stack (server to fronted) senior software engineer with significant project oversight. I was ready for a career change, but I still very much enjoy coding and problem solving! Here I'll highlight a few projects I'm proud to have worked on over the years.
Details:
  • Technology: Too much to list! Enduring favorites: Python, Jupyter Notebooks, Typescript, HTML/CSS, SQL, React, and Git
  • Fair Neuroimaging Lab: I built a Python pipeline wrapper to run the Human Connectome Pipeline for processing fMRI data on the OHSU HPC cluster. This pipeline was able to automatically resubmit jobs when they failed unexpectedly.
  • Memorial Sloan Kettering Cancer Center: I developed a visualization tool in D3.js that was used by nurses in a pilot study for proactive care for chemo patients who reported worsening symptoms in daily web-based surveys. This pilot showed a significant reduction in ER visits by chemo patients following treatment!
  • Janelia Research Institute: I maintained a visualization tool that was used to evaluate data quality of automated neuroimaging data segmentation using Three.js
  • Primary Kids: as part of a small team, overhauled an entire e-commerce site to reach full accessability compliance for visually-impaired users
  • Workflow diagram for the HCP pipeline
  • Data dashboard that includes a colorful 3D visualization
