Experience

athenahealth, Product Delivery Associate

Open-source contributions

VetLog, Python scheduler

PR #150 · Merged Sep 2026

  • Identified a reminder-content bug during upstream review: pets with existing medical logs were still included.
  • Contributed a filtered-list fix and mixed-case regression test; merged after maintainer approval.

OpenAI Codex, CLI bug investigation

Issue #48527 · Sep 2026

  • Tested text selection and clipboard behavior across Ghostty and GNOME Terminal on Linux Mint.
  • Reproduced a daemon-backed exit case that omitted the saved conversation name; the embedded control displayed it.

Selected projects

ContextPack, Python, tiktoken, PyTorch

github.com/HeyItWorked/ContextPack

Command-line tool that packs selected files into a fixed language-model token budget, keeps required files whole, and writes a report giving the reason every section was kept or dropped. The same inputs always produce the same output. 57 tests.

RiverRoot, Go, Docker, SQLite

github.com/HeyItWorked/RiverRoot

Self-hosted CI server that runs YAML-defined pipeline steps as host processes or in Docker containers, with marked steps in parallel, and stores builds in SQLite behind a REST API and dashboard.

MedCVE, Python, pandas, Jupyter, pytest

github.com/HeyItWorked/MedCVE

Analyzed 1,515 healthcare-tagged CVE records without dropping rows, exported nine JSON files to a static dashboard of charts and tables, and added tests that check the committed exports still match the raw data.

r3f3r, Vue 3.5, Spring Boot 3.5, Oracle

github.com/HeyItWorked/r3f3r

Referral follow-up tracker for a busy coordinator: log specialist referrals and spot overdue follow-ups from one compact dashboard, with due-date counts computed server-side.
