Things I build off hours — mostly privacy-first AI tools, agents, and small utilities I wanted for myself. Most have a write-up on the blog; all of them are open source.
Encrypted memory for AI agents
A Python memory library where the platform running the agent cryptographically cannot read what users store. Client-side encryption, encrypted semantic search, PII sanitization. Published on PyPI with a preprint on Zenodo.

Brain-inspired memory engine
A memory engine modeled on Hopfield-style attractor dynamics — retrieval by partial cues and context rather than keys or nearest-neighbour distance.

Private voice diary
A voice diary with semantic search where entries and the search index are encrypted at rest, and no content leaves the device to answer a query.

Voice-first AI health companion
Built for the Gemini Live Agent Challenge 2026 — a health companion you talk to instead of tapping through logging screens. Gemini Live, Veo 2, and Google ADK.

Autonomous blog-writing agent
An agent that turns any historical topic into a fully-functioning Jekyll blog, one milestone at a time — powered by local models via Ollama.

A daily AI newsletter written by agents
A pipeline that pulls RSS feeds, arXiv papers and company blogs every six hours, analyzes each item with a local model, stores it in Qdrant and publishes a daily Jekyll issue. Claude curates the source list weekly.

A J2ME classic, ported to Ruby
Procedurally generated mazes (randomized depth-first search) in the terminal, ported from Carol Hamer's J2ME maze game — a curses version and a dependency-free one.
