Contributed to the 0xPlaygrounds/rig repository by enabling Cloudflare Worker deployment readiness and improving backend reliability. Developed a feature flag system using Rust and conditional compilation to support Cloudflare Worker environments, allowing edge-enabled capabilities and flexible deployment across providers. Enhanced the codebase with API integration and feature flag techniques, wiring in dependencies and conditional paths for future edge rollouts. Additionally, addressed a critical serialization bug in Openrouter completion flows by refining optional-field handling, which improved robustness and reduced runtime errors. The work focused on backend development, leveraging Rust and Cloudflare Workers to deliver more reliable and adaptable infrastructure.
