February 2026: Delivery and decommissioning of PAssetHub integration in polkadot-js/apps. Key change: Removed the PAssetHub endpoint configuration from testingRelayPaseo.ts, signaling deprecation/removal of PAssetHub contract support. Commit f0b56faf93ddb558273a620a2de32ed792bd4598 ("remove passet hub (#12178)"). Impact and business value: Simplifies the test harness and reduces maintenance surface by removing deprecated contract integration, thereby lowering risk in CI/tests and aligning the app with the roadmap to sunset legacy assets. This also reduces potential integration drift with on-chain tooling and future deployments. Overall accomplishments: Codebase cleanup of deprecated integration, updated test configuration, and clear traceability for deprecation via commit and PR messaging. Technologies/skills demonstrated: TypeScript/JavaScript code cleanup, test harness simplification, deprecation planning and execution, version control discipline, and cross-team collaboration for feature sunset.

In September 2025, delivered CI Pipeline Optimization and Stability Improvements for paritytech/foundry-polkadot, focusing on reliability and faster feedback in the CI workflow.

February 2025 monthly summary focused on delivering interoperability and observability enhancements for the paritytech/polkadot-sdk. Implemented a new Web3 RPC endpoint to align with Ethereum tooling expectations, enabling external libraries to query essential client metadata and improve integration workflows.
