GeorgeS311578/README.md

Hi, I'm George Andres Sanchez Pozo 👋

Software developer. I contribute to open-source projects across different domains — energy modeling, e-commerce, seismic data, and web frameworks — and I build code-analysis tooling.

  • ✅ Merged PRs in HinetPy (Japanese seismic data / NIED).
  • 🐛 Reported and root-caused a confirmed bug in FastAPI.

🚀 Open-source contributions

Merged

  • HinetPy (seisman/HinetPy) — #151 show the original input in to_datetime parsing errors; #154 warn about a stale SAC file when the channel has no data.

Reported bugs and PRs

  • FastAPI #16489 — SSE/JSONL streaming emitted invalid JSON for non-finite floats (NaN/Infinity). I identified and root-caused the issue; the maintainer confirmed it and it was fixed in 0.143.3.
  • Medusa — PRs: refund_amount in returns, currency precision, admin error surfacing, among others.
  • OSeMOSYS (energy modeling) — fixes across the GNU MathProg, PuLP and GAMS implementations.
