Contributed to the smartcontractkit/external-adapters-js repository by developing an ICE Fx streaming price data adapter using the NetDania jsApi, incorporating a local price cache to enable reliable real-time pricing and faster partial updates. The implementation emphasized robust backend development with TypeScript and Node.js, supported by comprehensive end-to-end and unit testing. Addressed a critical security issue by enhancing URL sanitization for the ICE adapter, redacting sensitive parameters and providing fallbacks for malformed URLs to prevent data leakage. The work demonstrated strong skills in API integration, data sanitization, and integration testing, resulting in improved data reliability, privacy, and maintainability of the codebase.
