Worked on the FilOzone/pdp repository to deliver two core features focused on automation and reliability. Automated the extraction and publishing of ABI arrays from build outputs, integrating a dedicated Makefile target and CI/CD workflow to streamline artifact distribution and reduce manual intervention. Introduced an ownershipChanged hook with updates to the PDPListener service and verifier, expanding test coverage and mocks for ownership transfer scenarios. Modernized the CI/CD pipeline by removing npm, migrating build tooling to pyth-sdk-solidity, and updating dependencies. Utilized Shell, Solidity, and YAML to improve build reproducibility, enhance test reliability, and enable safer, faster feature delivery to customers.
June 2025 – FilOzone/pdp: Implemented two major features and modernized the CI/CD stack to boost reliability and time-to-value. 1) ABI Extraction and Publishing Automation: Automated extraction of ABI arrays from build outputs and published them via CI/CD. This includes a dedicated Makefile target and a release workflow to streamline distribution of ABI artifacts, reducing manual steps and accelerating downstream integration. 2) PDP Ownership Change Notifications and Tests: Introduced an ownershipChanged hook, updated PDPListener service and wiring through the PDP verifier, and expanded tests/mocks to cover ownership transfer scenarios and extra data handling, including CI/build changes and submodule management. 3) CI/CD Modernization and Quality Improvements: Removed npm from CI, migrated build tooling to pyth-sdk-solidity, updated dependencies, and simplified build steps to improve reliability and reproducibility. Strengthened test coverage and mocks to align with updated interfaces and contracts. Business value: Faster, more reliable ABI artifact distribution; robust ownership-change signaling and validation; reduced CI maintenance and improved build reproducibility, enabling safer deployments and quicker delivery of features to customers.
