Developed and launched the Tatum MCP server within the EmberAGI/arbitrum-vibekit repository, enabling AI agents to perform real-time queries on Arbitrum blockchain data. The solution was architected using Express.js, Node.js, and TypeScript, focusing on distributed systems design and secure, scalable data access. By supporting multiple transport methods and providing a toolkit for blockchain interactions, the server improved both developer experience and security. This work established a robust foundation for real-time, transport-agnostic blockchain data access, reducing integration friction and accelerating AI-driven insights. The project demonstrated full stack development skills and a strong emphasis on security-focused, API-driven server architecture.
