Open Source: ActiveCache Ruby Gem

Ruby applications frequently needed multi-layer caching (in-process memory + Redis + CDN) but existing solutions required committing to a single backend with no graceful fallback when a layer was unavailable.

Design a composable caching abstraction that allows transparent multi-layer lookups, automatic TTL management, and safe degradation when individual cache backends fail.

Developed ActiveCache as a Rails engine using a chain-of-responsibility pattern. Published with 95% RSpec coverage, full YARD documentation, and CI across Ruby 3.1/3.2/3.3 and Rails 7.0/7.1. Presented the library at RailsConf 2023 to an audience of ~300 developers.

1,200+ GitHub stars, 50+ production adopters, featured in Ruby Weekly. Received positive feedback from the Rails core team on the API design.
