Worked on enhancing Solana transaction confirmation reliability within the rango-client repository, focusing on improving end-to-end transaction robustness for users and integrations. Leveraged TypeScript and Node.js to migrate the confirmation flow from confirmTransaction to getSignatureStatuses, introducing a timeout mechanism that prevents indefinite waits and delivers clearer error messages. This approach addressed operational risks by reducing ambiguity in transaction outcomes and supporting better troubleshooting. The improvements strengthened adherence to service level agreements and lowered support overhead for downstream systems. The work demonstrated a strong grasp of blockchain concepts and API integration, delivering a targeted feature that improved transaction reliability without introducing new bugs.
