I build open-source tools that make messy data problems disappear. Currently building GoldenMatch — a Python entity resolution toolkit that deduplicates records, matches across sources, and maintains golden records. Zero-config, 97% F1 on academic benchmarks, scales to 10M+ records. I write about Python performance, fuzzy matching algorithms, privacy-preserving record linkage, terminal UI design, and LLM-augmented data pipelines. pip install goldenmatch pip install goldencheck
