During November 2024, Sandor enhanced the FrontFin/mesh-web-sdk repository by integrating Revolut Connect as a new broker type, expanding the platform’s financial operations capabilities. He implemented this feature through comprehensive API integration and backend development, updating interfaces and models to support Revolut services across core workflows. Sandor also upgraded the mesh-web-sdk to its latest version, focusing on improved dependency management and release readiness without altering existing functionality. Working primarily with TypeScript, he demonstrated proficiency in cross-service broker modeling and version control. The work delivered broader broker connectivity and streamlined onboarding for Revolut-related processes, reflecting solid engineering depth within a short timeframe.
