Worked on the cowprotocol/services repository over four months, delivering four backend features in Rust with a focus on reliability and maintainability. Developed expanded end-to-end and unit testing for the Refunder crate, surfacing RefundStatus into core logic and introducing a trait-based architecture to decouple backend dependencies, enabling easier testing and backend interchangeability. Implemented race-aware mempool submission outcome tracking, improving the accuracy of system metrics and observability by distinguishing between successful, superseded, and failed attempts. Established the foundational solana-indexer crate to support future Solana settlement indexing, demonstrating skills in Rust crate development, software architecture, and incremental, test-driven engineering practices.

Jun 1, 2026June 2026 - cowprotocol/services: Focused on foundational Solana settlement indexing work. Key feature delivered: created a barebones solana-indexer crate to serve as a foundation for future settlement indexing components. Major bugs fixed: none in scope this month. Overall impact: establishes architecture to support Solana settlement data processing, enabling incremental feature development and safer refactoring, improving modularity and long-term maintainability. Technologies/skills demonstrated: Rust crate design, monorepo structuring, incremental scaffolding, and commit-level traceability.

May 1, 2026Summary of May 2026 focusing on system observability and reliability improvements in cowprotocol/services. Delivered a race-aware Mempool Submission Outcome Tracking and Metrics Accuracy feature that distinguishes winning mempool successes from superseded or failed attempts, resulting in clearer, more actionable performance metrics and dashboards. The change prevents errors from losing race mempools from being counted as failures and ensures all mempool outcomes are labeled consistently. Core work includes introducing an Outcome enum, adjusting Mempools::execute to defer metric updates until outcomes are resolved, and refactoring metrics/logging in infra/observe to emit per-attempt logs without conflating metrics. The feature is verified by existing driver tests and manual Prometheus verification instructions. Commit reference: 3bc9afe03cba56cbdb4dfa78960c9f8ea0b2a6ef. Co-authored by José Duarte and MartinquaXD.

Feb 1, 2026February 2026 monthly summary for cowprotocol/services focusing on the Trait-based Refunder Service Architecture. Delivered a decoupled, test-friendly design enabling easier unit testing and backend interchangeability (DB and blockchain backends). Added trait abstractions and infrastructure implementations, refactoring for improved testability, and a focused unit test suite. Overall, this work reduces integration test overhead, accelerates iteration on refunds logic, and establishes a solid foundation for backend-agnostic deployment.

Jan 1, 2026January 2026 monthly summary for cowprotocol/services focusing on end-to-end testing improvements in the Refunder crate. Delivered expanded E2E tests across refund scenarios and promoted RefundStatus to the main crate logic, while resolving a blocking compilation error in the shared crate. The changes improve reliability, maintainability, and confidence in production refunds, enabling faster validation cycles for future changes.
