Frontend architecture · TypeScript · browser platforms · applied AI
11+ years building software, currently on enterprise web products in Berlin. I work in the layer where a product stops being a UI and starts being a system: state that survives a background job, a message contract across three processes that cannot share memory, an inference budget that has to hold before a native call.
Almost everything here started the same way: something got in my way on an ordinary Tuesday, and the missing tool looked like a good excuse to build it. Getting each one from works for me to works for you is the part I stay for.
01 · SELECTED WORK
Automatist MOBILE-FIRST AI AUTOMATION · ON GOOGLE PLAYRecurring AI tasks, scheduled from a phone, with a real choice between cloud, on-device, and offline models. No backend, your own keys, and a preflight token budget because an oversized prompt aborts the native runtime rather than throwing. Free and open source.

Easy Web Navigation CHROME WEB STORE Focus order, landmarks, and the tab path, drawn straight onto the page instead of filed as a report. A Shadow DOM overlay so the tool never joins the tab order it measures, and zero required host permissions. TypeScript React MV3 · Chrome Web Store · Source

Local Browser Automation Bridge LOCAL PROTOTYPE Four processes that cannot share memory (dashboard, Node backend, MV3 service worker, content scripts) held together by typed contracts, a SQLite queue, and a request registry that gives a WebSocket the request/response semantics it does not have.

Re-Phraser CHROME WEB STORE Your selection goes to the AI tab you already have open. No backend, no API-key box: their subscription, their account, nothing in the middle. Chrome Web Store · Source |
Psalms Way GOOGLE PLAY 81 translations and 47 interface languages, entirely offline, which is why the bundler needs a static module map instead of a computed path. Google Play · Source · Extension |
ENGINEERING LAB · design-intelligence, a derived design-guidance layer synthesized from 74 brand analyses. TOOLING · my code-cleanup workflow as a Claude Code plugin, a lead agent coordinating seven specialist workers, and its marketplace. COMMUNITY · Prompt Save Reuse, on the Chrome Web Store and shaped by outside pull requests.
