In more detail

Three projects in detail.

Chrome Extension · Live in Store / 2026

Political Bias Detector

Problem: I wanted a political-leaning estimate, a summary and verifiable claims to be available while reading an article.
My contribution: I automated the workflow from an open article to its analysis: the extension captures the content, while the FastAPI backend assesses political leaning, summarizes the text and identifies verifiable claims. A dashboard manages API access and usage.
Outcome: The extension is published in the Chrome Web Store.

Chrome Extension · Self-hosted / 2026

Application Assistant

Problem: Job listings, tailored documents and the status of each application had to be managed across several tools.
My contribution: I automated the workflow from a job listing to submitting the application: the extension captures listings, helps create tailored documents and places them directly into upload fields. A Kanban view keeps applications and their status together.
Outcome: The extension is published as an unlisted Chrome Web Store item and used with a self-hosted backend.

Flight Planning Automation / 2025

Flight Planning App

Problem: Before a flight, weather, NOTAMs, airfield information, navigation and weight limits have to be gathered from several sources.
My contribution: I combined the recurring steps of flight preparation into one workflow and automated them where possible: retrieving weather and airfield data, calculating navigation, and checking weight and centre of gravity.
Outcome: It turns flight preparation, from the weather briefing to centre-of-gravity calculations, into one workflow.
