I build web apps

Frontend lead from Ukraine, living in Valencia. Sixteen years of web, the last few running a whole fintech frontend on my own. These days agents write most of the code β€” I write the spec, make the calls and read what matters.

the one nobody else has

My messengers, searchable by AI

Two WhatsApp numbers and Telegram β€” years of chats, voice notes, photos and documents β€” archived at home and wired into Claude through MCP. A search engine and a secretary for my own messages.

πŸ—„οΈEverything, at homeEvery message lands in SQLite on my server the moment it arrives β€” nothing lives only in someone's cloud.
πŸŽ™οΈVoice notes become textwhisper runs on the laptop's own GPU. No audio ever leaves the house.
πŸ”ŒClaude can ask it anythingMCP tools search across every chat, language and year β€” no vector database, just good tools.
πŸ“‘A daily radarAn agent wakes up when chats go quiet, shows only what I haven't seen and drafts the replies β€” straight into Telegram and Gmail.
πŸ›‘οΈParanoid by designSending is off. Every message an agent reads is treated as untrusted input β€” prompt injection is planned for.
πŸ–±οΈOne click backAny item opens the right chat in the right app, through a small Chrome extension.

He moved it to Monday 17:30 (WhatsApp, voice note). You haven't replied β€” a draft is ready.

A TRMNL panel on my own server: inside and outside temperature, the air-con, the week β€” and the radar of chats waiting for an answer.

how I workAI in every direction

Not a chatbot in a tab β€” agents with tools, a spec and limits.

At workClaude Code writes, I review everything that ships to production payments β€” every change, twice.
At homeI'm the product owner: the idea, the spec, the decisions, living with the result. The agent does the rest.
On the wallAn e-ink screen and a dashboard that know what's going on at home β€” fed by the same agents.
Spending tokens wiselyModels run only when there is something new. A quiet day costs nothing.
