Work History

May 2026

10 Commits • 2 Features

May 1, 2026

May 2026 performance summary for osmlab/name-suggestion-index: Expanded the brand catalog across multiple datasets, improved data integrity through Wikidata cleanup, and reinforced ID generation reliability through targeted tests. Deliveries enhanced discovery, accuracy, and data quality for downstream consumers and tooling.

April 2026

15 Commits • 3 Features

Apr 1, 2026

April 2026: Expanded store coverage with new global and regional spiders, strengthened data extraction and parsing across the spider suite, and tightened maintenance to improve data quality and CI safety. Delivered Pop Mart global spider, Norway-specific spiders, and Kjell & Company spider, enabling broader product coverage and more accurate scraping. Core spider improvements across existing spiders improved data extraction, URL handling, and parsing, with new exposure features such as WiFi and drive-through (Carls Jr US). Maintenance and licensing updates standardized dataset attributes, added LICENSE handling, and improved CI/file-upload safety. A major bug-fix sprint resolved issues across multiple spiders (e.g., TortillaGBSpider, Jiffy Mart US, ZeemanSpider, GoodwillSpider, LittleCaesars, IkesUSSpider, DhlExpressGBSpider, HussarGrillZAZMSpider) and fixed CarlsJrUS sitemap rule, enhancing reliability and data quality. Technologies/skills demonstrated include Python-based spider development, robust data parsing, URL normalization, CI/CD practices, pre-commit collaboration, and cross-team co-authored fixes.
