Reed Pennock

Built ppstats, a 27-kernel statistics package; native skew and kurtosis ran about 25 times faster than SciPy on arrays of one million elements.

• Submitted PostPython compiler fixes for silent Float16 miscompilation, non-finite constants, and C symbol collisions, with end-to-end regression tests.
• Contributed QA and UI/UX fixes to Collab, an AI workspace; led release-note videos and documentation and built Claude Code and Codex workflows for implementation and code review.

Leading development of Python pipelines that process terabytes of calcium-imaging video and EEG/electrophysiology data for a nine-person neuroscience research team.

• Re-architected the analysis package into extensible object-oriented components and introduced GitHub Actions CI and comprehensive end-to-end testing.

Mentored more than 100 students in Python, recursion, object-oriented programming, and software testing through labs, office hours, and individual code reviews.

• Reviewed more than 200 programming projects and provided actionable feedback on correctness, algorithmic efficiency, code quality, and style.

Built a fault-tolerant pipeline that collects, deduplicates, and stores timestamped campus gym imagery and metadata after reverse-engineering an Android camera API and anonymous OAuth flow.

• Developed a computer-vision pipeline using YOLO, tiled inference, spatial zones, and equipment polygons; reduced mean count error from 6.0 to 1.5 people in an initial manually labeled evaluation.
• Deployed collection and inference on Linux with systemd recovery, stale-feed detection, atomic database snapshots, and secure Tailscale/Syncthing synchronization; optimized GTX 1070 Ti inference to run nine detection passes per image in about 0.5 seconds.

Built a progressive web app that generates personalized weekly meal plans from dietary, budget, calorie, and meal-pattern preferences.

• Implemented Supabase authentication, persistent planning history, offline support, database migrations, cached product resolution, Walmart cart handoff, and automated CI and security checks.

Built a real-time multiplayer chess platform with concurrent game sessions, legal-move validation, authentication, and persistent game storage.

Built a 27-kernel statistics package in PostPython and cross-validated Python, native shared-library, and NumPy ufunc results against SciPy and NumPy.

• Native skew and kurtosis ran about 25 times faster than SciPy on one-million-element arrays in benchmark runs.

Developed a modular analysis pipeline for calcium-imaging video and EEG/electrophysiology data, with components for processing, visualization, and aligning recordings across modalities.

• Reworked the package into extensible components and added CI and end-to-end tests for the neuroscience research team.

Built an interactive command-line tool for practicing Finnish noun, adjective, and verb inflections with morphology-generated answers and focused drills.

• Added custom vocabulary imports with validation, review of ambiguous forms, and safe replacement of saved sets.

Built a tool that extracts Finnish vocabulary from web pages and documents, reduces words to their base forms, and exports reviewable Anki-ready decks.

• Supports PDF, DOCX, and text input, cached translations, and a browser interface for editing cards before export.

• Vice President, BYU Linux Association (2026–present): lead workshops for 20–30 attendees on Linux, open-source software, and systems tools; help students make open-source contributions.
