Dave Corson-knowles

Worked across repositories such as rubocop/rubocop-rspec, Shopify/spoom, and rubygems/rubygems to deliver features that improved code quality, static analysis, and test reliability. Enhanced dead code detection in Ruby and Rails projects by expanding plugin capabilities and refining analysis for ActiveRecord and GraphQL usage. Strengthened test suites and contributor onboarding through expanded RSpec coverage and updated documentation, aligning with CI and coverage standards. Introduced new RuboCop cops and configuration updates to enforce stricter linting and safer code edits. Leveraged Ruby, YAML, and Shell scripting to implement backend improvements, focusing on maintainability, type safety, and reducing regression risk in collaborative environments.

May 1, 2025

May 2025 focused on strengthening spoom's dead code analysis for ActiveRecord usage in Shopify/spoom. Delivered an enhancement that correctly detects methods referenced within ActiveRecord callback conditions (if/unless) and extended the analysis with a dedicated constant for callback conditions in the ActiveRecord plugin, accompanied by updates to the spoom.rbi references to reflect the new capability. This work improves precision and reduces risk by surfacing unreachable code paths tied to model callbacks, supporting safer refactors and faster reviews.
