Reed Pennock

Developing PostPython, a Python-to-C ahead-of-time compiler, with a focus on code generation, numeric-type correctness, and useful unsupported-feature diagnostics.

• Built accuracy, edge-case, and mutation-testing infrastructure for 27 statistical kernels; cross-validated Python, native shared-library, and NumPy ufunc results against SciPy and NumPy.
• Applied agent orchestration with Claude Code and OpenAI Codex in development workflows; wrote technical documentation and release notes and coordinated interns producing technical videos.

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.
