PROFILE

Filipe Azevedo

Worked extensively on backend systems for the Graph ecosystem, delivering features and fixes across the graphprotocol/indexer-rs and graphprotocol/graph-node repositories. Built and integrated the Data Indexing Payment System (DIPS), implementing GraphQL and gRPC APIs, configurable workflows, and multi-network support using Rust, Protocol Buffers, and SQL. Enhanced data integrity with IPFS-based validation and escrow-based signer checks, and improved system reliability through TLS configuration fixes and CI stabilization. Refactored database architecture for efficient metadata retrieval and streamlined dependency management. Also contributed to zed-industries/zed by improving remote reconnect logic, applying asynchronous programming and robust testing to ensure seamless user experiences.

February 2026 — zed-industries/zed monthly update focused on remote reconnect stability. Key deliverable: fix remote reconnect when the server is not running, preventing an error dialog and enabling a fresh connection without manual project switching. The change updates the remote connection logic and includes tests to ensure reliability in this scenario. Impact: smoother remote workspace experience, reduced user friction and support inquiries when servers die, and more robust handling of dead-server states in production. Technologies/skills demonstrated: connection lifecycle handling, test-driven development, targeted code refactor to gracefully handle ServerNotRunning, and clear release-note communication.
