Things I've built
Deliberately spread across applied AI, data science, and visual storytelling. The through-line isn't a single stack: it's taking each one from a blank page to something real, finished, and genuinely pleasant to use.
jobradar
Job search for Switzerland that reads every posting so you don't have to. It scores each one on skill fit against your CV and interest fit against a page you write about what you want next, then drafts a tailored CV and cover letter in the posting's language. Runs daily in the cloud; released as an open-source template.
Meditations RAG
A retrieval engine over Marcus Aurelius' Meditations: you describe what's troubling you, it returns the fitting passages with citations, in Marcus's own words rather than an LLM's. Built solo at Hack Apertus on Apertus, Switzerland's sovereign LLM, which routes each message and expands the search: that cut unhelpful passages in the top two results from 48% to 22%, with the open model holding its own against Claude.
Strohsack AI
A personality-driven AI agent that embodies a beloved plush bear, with persistent memory across sessions, LLM tool-use for durable facts, and both CLI and Streamlit interfaces.
Referral Analytics
End-to-end referral-program analysis on synthetic data: a referral-cascade graph, a two-proportion z-test, and an interpretable XGBoost model (Weight-of-Evidence + SHAP). A privacy-safe adaptation of real production work.
Employee Turnover
Capstone of Google's Advanced Data Analytics certificate: predictive modeling of employee attrition, from exploratory analysis through to a deployed-quality model.
Reptilia Antiqua
An illustrated field guide to dinosaurs for small children and the parents reading along. Its timeline isn't to scale: busy eras are stretched, empty ones folded away, and the survivors sit past the asteroid line. Swipe, arrows or keyboard all browse the same way; names are pronounced in six languages, the full interface in three.
Jalal al-Din's Journey
A story map of a 13th-century prince's 11-year, 13,750 km flight from the Mongols, designed for phones as much as desktops. The story panel starts collapsed on small screens, popups pan clear of the controls, and the animated ride waits at each stop long enough to read it, pausing on its own when you open the glossary.
