Software

I build data science tools for economists and anyone who works with data. These projects aim to support common workflows and help with everyday tasks, mostly built with R:

tidyllm

tidyllm is an R package designed to access various large language model APIs, including Anthropic Claude, OpenAI, Google Gemini, Perplexity, Groq, Mistral, and local models via Ollama or OpenAI-compatible APIs. Built for simplicity and functionality, it helps you generate text, analyze media, and integrate model feedback into your data workflows with ease.

SIAB DuckDB

SIAB DuckDB is a fast and portable implementation of the SIAB preparation workflow using DuckDB. This project reimplements the data preparation process for the Sample of Integrated Labour Market Biographies (SIAB), based on the original Stata reference code by Wolfgang Dauth and Johann Eppelsheimer (2023).

Semantic Paper Search

Semantic Paper Search is a semantic search engine for economics papers on RePEc. Traditional keyword search misses relevant research due to jargon, synonyms, and rigid matching. This tool uses LLM-powered semantic text embeddings to find economic papers by meaning, not just words—capturing hidden connections and context.

Shoddyprinter

Shoddyprinter is a whimsical R tool that gives your beautiful ggplot2 charts the aesthetic of a poorly calibrated office printer. Think jagged lines, misaligned labels, and broken toner style — perfect for presentations with a sense of humor or commentary on data visualization.
