Builds

Personal AI triathlon coach. Pulls every workout from Intervals.icu, scores it against the week's plan with Claude, texts feedback on Telegram. Plans the next week every Sunday.

Tiny self-hosted SQLite REST API behind tri-coach. Replaced an Airtable base after the upstream account got blocked. ~250 lines of Express, single Docker container, zero recurring cost.

System-wide hotkey: select text in any app, hit a key, get a polished rewrite pasted in place. Tray-icon controls for language and tone. V3 added push-to-talk dictation via local Whisper.

Telegram bot that summarises YouTube links, articles or long text. Personal antidote to the never-watched "watch later" pile.

My second brain. Personal LLM-friendly knowledge base — Obsidian for reading, Claude for writing, QMD for full-text search, Syncthing keeping my Mac and VPS in lockstep with no cloud middleman. Karpathy-style topic-led wiki, with sources, entities and concepts as separate page types. Hermes, XBookmarks and Voice Notes all feed into it.

VPS-side agent with two personalities. 'Vault-aware' answers questions over my knowledge base in read-only mode; 'vault-writer' drafts new pages into a sandboxed inbox. Talks to me on Telegram. Routes most queries to Grok 4.1 Fast — Sonnet only when needed.

Telegram bot that turns saved tweets, articles and YouTube links into structured markdown notes in my vault. Same pattern as Voice Notes — collect everywhere, store in one place.

Telegram voice memo → Whisper transcription → Claude categorisation (idea / todo / other) → markdown file in my vault, with an undo button. One n8n workflow.

Webhook command runner so phone-side Claude (or me, on a train) can restart a container, tail logs, redeploy or run an allow-listed script on my VPS.
