i build data platforms
and agents to play with them.

data & ml engineer at plex, in curitiba. at home i run a personal warehouse — 23 sources, seven years of my own life — with an agent living inside it.

everything below is drawn from that warehouse, live: every number was queried when you loaded the page, straight from .

from my phone, my plex server, spotify and kindle.
click one — each runs a live query against the warehouse and shows you the sql.

what it holds

distinct entities, not stored rows. bronze keeps a full snapshot per ingestion run, so raw counts overstate some sources by up to 1,200× — the honest number is the one shown.

where the data is thin

average metrics captured per day, by month. the 2019–2023 band is a single backfilled apple health export; density arrives when each source was actually connected, and the step in mid-2026 is the agent going in.

coverage

when i do things

hour × weekday, from the two sources with a real clock — watching and listening.

rhythmhour × weekday

where i go

named places and the trips between them. the coordinates exist, but they all sit within a few km of where i sleep — so the graph carries the shape, not the address.

the orchestrator's own run log. the page is only as live as the ingestion behind it.

the agent can do things

the warehouse is the memory. the agent on top of it runs my actual life — telegram, its own mailbox, a browser, a credential vault, a task system. it has 245 tools behind 41 skills, and a deterministic router decides which ones a message needs.

explore any metric of me

every daily metric the warehouse tracks, plus the analytes the agent extracts from my lab pdfs. pick one; the chart is live and the sample size is always shown.

things i've built

agents in production at work, and a pile of my own. two of these have other people depending on them; one trades real money.
