PROFILE
Mike Bennett
Over five months, contributed to the datacite/lupo repository by building and refining backend features focused on deployment reliability, API security, and operational observability. Delivered a secure Datafile Credentials API using Ruby on Rails and AWS integration, enhanced Docker-based deployment workflows, and automated Nginx configuration for dynamic environments. Improved code quality through RuboCop compliance and removed legacy dependencies to reduce security risk. Addressed architectural issues with the Nokogiri gem and aligned Ruby versions for consistent runtime compatibility. Expanded RSpec and VCR-based integration testing, strengthened CI/CD pipelines, and introduced custom metrics monitoring, resulting in a more maintainable and robust backend platform.

Jan 1, 2025Month: 2025-01 — Delivered robust DOI random ordering improvements and stronger randomness testing/CI for datacite/lupo. This includes applying random sorting only when random='true', preventing cursor-pagination with random sampling, and improved Doi model error handling and style. Expanded tests and CI: removed hardcoded seeds, added specs for random order with mutually exclusive pagination, introduced VCR cassettes, and upgraded CI workflows. Impact: more reliable and predictable DOI search results, fewer query errors, and faster feedback loops for QA and development. Technologies: Ruby/Rails, RSpec, VCR, RuboCop, CI pipelines.
