Worked on FuelLabs/fuel-core, focusing on backend and blockchain development using Rust and TypeScript. Delivered features to synchronize block production with Data Availability (DA) block height, ensuring blocks are only produced when DA data is current, which improved cross-layer reliability. Enhanced the gas price service by implementing an asynchronous wait mechanism, allowing tests and deployments to proceed only after gas price synchronization, thus reducing flakiness and increasing determinism. Addressed a bug in the Coins endpoint to ensure accurate asset-type retrieval when asset IDs are omitted, and expanded test coverage to prevent regressions, supporting more reliable downstream integrations and reporting.

Aug 1, 2025In August 2025, delivered Data Availability (DA) block height synchronization in FuelLabs/fuel-core to ensure block production waits for the DA height before proceeding, improving cross-layer reliability and determinism. This change aligns block production with the DA layer, reducing risk of producing blocks on unavailable or stale DA data and enhancing overall system robustness.

May 1, 2025May 2025 — FuelLabs/fuel-core: Focus on reliability and correctness of client data retrieval. Delivered a targeted bug fix for the Coins endpoint and strengthened test coverage to prevent regression. The change improves asset-type accuracy for client lists and downstream integrations, aligning with API expectations and reducing misreport risk. Key accomplishments: - Fixed Coins endpoint to return all asset types when asset ID is omitted, addressing an incorrect default behavior. - Added a dedicated test to verify endpoint behavior when no asset ID is provided, increasing test coverage for endpoint logic. - Ensured traceability with a dedicated commit and descriptive message. Business value: - Improves accuracy of asset-type aggregation in client apps. - Reduces potential misreports in downstream tooling and dashboards. Note: All work is tracked under FuelLabs/fuel-core with the following commit.
