Worked on the hyperledger-labs/splice-wallet-kernel project, delivering core wallet SDK features and infrastructure for blockchain-based contract management. Over six months, built extensible plugin systems, implemented robust pagination and caching strategies for large dataset handling, and enhanced multi-party workflows with secure transaction verification. Applied TypeScript and Node.js to develop type-safe APIs, improve error handling, and optimize performance through caching and CI/CD automation. Focused on reliability by expanding test coverage, strengthening logging, and refining SDK initialization. The work enabled scalable, resilient contract operations and streamlined developer experience, supporting both backend and full stack development needs in a production blockchain environment.

Jun 1, 2026June 2026: Delivered pagination for active contracts in the ACS Reader with a new cached page retrieval method, enabling faster access to large datasets. Expanded test coverage across wallet SDK and ACS components and strengthened CI to run the full unit test suite, increasing reliability and reducing regression risk. No major bugs reported in this cycle; focus was on performance, stability, and quality engineering. Impact: faster data access, higher confidence in wallet/ACS correctness, and a stronger foundation for future scalability. Technologies/skills demonstrated: pagination/cache design, comprehensive unit/integration testing, CI automation, and robust code quality practices within the splice-wallet-kernel project.

Jan 1, 2026January 2026 – splice-wallet-kernel: Strengthened Active Contracts Filtering to boost flexibility, reliability, and production readiness. Delivered a feature enhancement to gracefully handle cases where neither templateId nor interfaceId is provided, plus targeted robustness fixes with regression tests. This reduces edge-case failures in contract queries and establishes a solid foundation for future contract-filtering enhancements.
