Worked on the smartcontractkit/ea-framework-js repository to deliver FEED_ID_JSON output and deterministic cache key generation, focusing on enhancing multi-chain integration stability. Addressed a 504 error in the Streams adapter’s view-function-multi-chain path, improving runtime reliability. Leveraged Node.js and TypeScript to implement deterministic, sorted cache key generation with SHA1 hashing, ensuring consistent cache behavior across environments. Enhanced feed identity exposure by introducing configuration-driven JSON output, supporting downstream integrations and debugging. All changes were delivered with clear traceability to specific commits, facilitating performance reviews and audits. Demonstrated full stack development skills through targeted improvements to caching and configuration management workflows.
