Alex contributed to the streamingfast/substreams and grafana/mcp-go repositories, focusing on backend and CLI development using Go, Protocol Buffers, and gRPC. Over three months, Alex delivered features such as improved registry publishing UX, enhanced error handling, and support for hyphenated package names, streamlining package management and CLI configuration. In grafana/mcp-go, Alex extended the MCP server to support descriptive prompt registration and richer prompt metadata, improving governance and automation. Alex also implemented the Substreams Attestation Protocol, adding signed attestations and operator public key propagation to RPC messages, which strengthened economic security and verifiability in streaming data pipelines.

Month: 2025-01 — Focused on strengthening economic security and RPC reliability for the streaming pipeline. Delivered the Substreams Attestation Protocol enhancement with signed attestations and operator public key propagation in BlockScopedData and SessionInit messages, aligning with GIP-0082. This lays the groundwork for verifiable attestations across RPC interactions and improves trust in data processing pipelines.

December 2024 — grafana/mcp-go: MCP Server enhancements delivering descriptive prompt registration and richer prompt listing, plus support for prompt arguments. Key changes include AddPrompt with name and description, and handleListPrompts now returning full prompt details (metadata) to enable richer UX and governance. Commit d30e492fc45a2586064da4cdb92e7dc067e96e94 (Implement arguments on Prompt) adds dynamic prompt handling for better flexibility. Impact and value: Improves prompt governance, discovery, and end-user interaction; reduces manual prompt management overhead and enables more expressive automation. Demonstrates Go backend development, API design, and data modeling skills.
