Mar 2014 - Sep 2021
Syntactic patterns of HTTP user-agents used by bots / robots / crawlers / scrapers / spiders. pull-request welcome :star:
Role in this project:Backend & QA Engineer
Backend & QA EngineerContributions:3 reviews, 115 commits, 333 PRs in 7 years 7 months
Contributions summary:Martin primarily focused on improving the validation of user agent patterns within the crawler-user-agents repository. They implemented JSON schema validation to ensure data integrity, added checks for duplicate patterns and instances, and improved the overall validation logic. The user also extended validation to check for unescaped slashes and implemented tests in PHP to validate the patterns against examples.
