devkill
Finds and deletes the build artefacts eating the disk — node_modules, target, .next — across every language at once, with explicit symlink and version-control guards.

a few words about me
-- i spent time in Krakow, came back to Athens, and ran into the same wall everyone here does: high rent, few options, and a roommate search that felt unsafe --
-- MyRoomie started as the answer to my own problem, and became a housing platform built around compatibility and verification --
-- before that: fifteen years across marketing, media and ecommerce — Apple, iSquare, Antenna, MAD TV, The Flying Pot --
my tech stack
-- what is actually in production: TypeScript, React and Next.js on the surface, Go and FastAPI underneath, PostgreSQL for anything that has to still be true tomorrow, and Tauri when it needs to leave the browser --
my blog articles
-- what i learned the expensive way, written down before i forget it: housing systems, developer tools, and the decisions underneath both --
-- written in the open, because a thing i only half understand is a thing i cannot explain yet --
The in-between moments are the product too
Loading screens, error messages, confirmation dialogs — the liminal spaces of a product shape how it feels more than the features do

Schema drift is the tax of AI-assisted coding — why it happens to every vibe-coded project, and the tool I built to squash it

Buyers increasingly never visit your site — they ask an AI, and the AI recommends whatever it can parse. The full pattern: markdown mirrors, llms.txt, agents.md, and content negotiation

on the record
-- housing is a subject Greek television keeps returning to, and MyRoomie put me on the other side of that conversation --
-- these are frames from the segments themselves, not logos on a wall: each one carries the broadcaster's own branding --

Pitching MyRoomie on Dragons' Den Greece, on ANT1.
Dragons' Den Greece — ANT1pitch2023
The on-air agreement: 50,000 euro for 7.5%, against an opening offer of 25,000 for 3%. It did not close after the show — the figure is often quoted as funding, so it is worth saying plainly here.

tools i built
-- the ones i reach for on an ordinary day, and the reason each exists is that i got tired of not having it --
-- six of them, not the whole list: shipped below is the full ledger, this is the daily set --
-- the rest of the ledger, with the version each registry answers, lives under /utils --
git-herd
Runs one git command across many repositories concurrently, and leaves the dirty trees alone.
run it
git-herd pullbiome-to-oxc
Moves a project from Biome to the Oxc toolchain, translating the config instead of resetting it. Dry-run and rollback, because a linter migration should not be a one-way door.
run it
npx biome-to-oxcoxc-audit
Reads a project's actual stack and configures oxlint and oxfmt to match it, rather than starting from a generic preset.
run it
npx oxc-auditai-changelog-generator
Reads the diff and writes the changelog entry. Has an MCP server, so an agent can do it without me.
run it
npx @entro314labs/ai-changelog-generatorupdate-ng
Updates everything a machine has installed, across every package manager, in one pass.

in order
-- the same career as above, on an axis, so the gaps are visible too — a decade of marketing, then a hard turn --
-- built from the roles, awards and papers already on this page rather than written out again, so it cannot go quietly stale --
my various projects
-- the things i actually built, rather than a list of technologies i have touched --
-- a housing platform with paying users, data infrastructure underneath it, and the developer tools that came out of needing them myself --
-- some are in production, others are side-projects that let me explore new technologies --
---
Flatsharing and housing, built around compatibility and verification

An energy-state model for neurodivergent-friendly software
shipped
-- a project is not finished when it works on my machine, it is finished when somebody else can install it --
-- so this list is only what a registry will answer for: 56 published artefacts across npm, crates.io and github releases, every one of them a link you can check --

not finished
-- the other half of the list: things that are not finished, and would be misrepresented by sitting next to something you can install --
-- running means deployed and reachable by me, not open to you. building means it works and is not packaged. designed means it exists on paper and nowhere else --
CapySquash
runningSquashes a pile of accumulated Postgres migrations into one coherent schema, without losing what the intermediate steps proved. The web platform is live; the paid engine is not.
Ergosphere
runningA hosting platform in the Railway and Render shape. Dashboard is up, the control plane behind it is not answering yet.
EntroMail
runningMail infrastructure with a working dashboard and an API host that currently does not resolve. Honest state: half a product.
Mpath
runningProject tracking that follows how work actually moves rather than how a board says it should. Live, without billing or role permissions.
Nami
runningA planner built around variable attention rather than a constant one — the same premise as Kumbatio, aimed at a person rather than an interface.
BrewDB
runningA searchable index of Homebrew formulae that answers faster than `brew search` and shows you what a formula actually pulls in.
WingetDB
runningThe same idea for Windows package manifests: search, inspect and compare without the terminal round trip.
PolarisAI
runningA marketing platform with AI in the loop rather than bolted on the side. The deployment is access-protected while the integrations are rebuilt.
Meltemi
buildingA native mail client for people who have given up on the web ones. Works locally; the release and provider setup are not done.
Astrolabe
buildingA git client that shows the state of many repositories at once, rather than one window per repository.
Snippr
buildingA snippet manager that lives where you type instead of in another app. Held back deliberately: a credential is tracked in the repository and that has to be redesigned before anything is packaged.
devtop
buildingA process monitor that attributes CPU and memory to the project causing them, not the binary. Builds from source, nothing packaged.
Dots and Bricks
buildingProject scaffolding from a catalogue of composable pieces, rather than one template you spend an afternoon deleting.
EmuHub
buildingA single front end over the emulator and game-library tools that each insist on their own.
Desk
designedA Tauri project manager for developers with too many repositories. An arm64 build exists; signing and notarisation do not.
MIMY
designedA dating app built on the compatibility model MyRoomie already uses for housing. Fully specced, no code.
Startup OS
designedThe operational scaffolding a founder rebuilds from scratch every time: cap table, hiring, metrics, board reporting.
PressDB
designedA structured record of who covers what, so a press list stops being a spreadsheet somebody has to maintain by hand.
FundDaddy
designedFunding-round tooling, from the side of the person raising rather than the person investing.
papers
-- a five-paper series on one premise: clock time is a poor proxy for capacity, and the gap falls hardest on the people whose capacity varies most --
-- written implementation-first: each one describes something i built and released, not something i propose to --
-- they are preprints. none has been peer reviewed, and the outcome claims in them are hypotheses with an evaluation agenda, not results --
