Software engineer building data systems and practical automation. I like taking messy operational problems and shipping the system that actually runs them.
Right now I'm the only engineer at a small real estate operator, where I own the whole stack — schema design, ingestion, deployment, backups, and the support call when production breaks. Before that: two summers building Node/GraphQL backend services at a Georgia Tech CREATE-X startup, and two years leading a wearable-sensor machine learning research project at Elon.
Things I've built
Tail of the Dragon Classifier · live demo Eight-class vehicle classifier reaching 99.12% on 23,980 held-out photographs. I screened seven architectures before training ConvNeXt Tiny, then read all 210 remaining misses and wrote up why I stopped instead of chasing another point.
ElonMealsDB · live demo Dining data platform: Python scraper, normalized MySQL schema, read-only Express API with parameterized queries, React frontend. Dockerized, with typecheck, tests, build, and health checks verified on every change.
Wearable Sensor Research About a million raw accelerometer rows across 30 participants. 500+ TensorFlow experiments tracked in MLflow, 96.3% accuracy on step detection, evaluated with subject-independent Leave-One-Group-Out so the numbers reflect people the model never saw. Manuscript submitted to IEEE EMBS BHI 2025.
Tiny NLA Lab Laptop-sized reproduction of the core loop from Anthropic's Natural Language Autoencoders work — hidden activation to English explanation and back to reconstructed activation. Runs locally on Apple Silicon with a 135M-parameter model.
AI Resume Tailor LaTeX resume pipeline driven by a structured facts file, with reviewer agents that flag unsupported claims, layout breaks, and formulaic wording before anything gets sent.
Eufy Lock Codes Local MCP server for smart-lock access codes across rental properties. Previews every change before it runs, expiring execution tokens, redacted audit logs, verification after.
Mostly Python, SQL, and TypeScript. I write things up at chadd.blog.
