During March 2026, contributed two features focused on backend development and system design. Developed a Hedera SDK Batch Processing Example in the hiero-sdk-js repository, enabling batch processing of multiple account transactions through setInnerTransactions and enhancing API integration workflows. Advanced the initial design and documentation for Block Node Support in the Hiero Mirror Node Explorer, outlining the structure and intended functionality to support future enhancements. Work emphasized clear documentation and alignment with repository standards, facilitating adoption by downstream teams. Utilized JavaScript and Markdown to deliver maintainable code and comprehensive proposals, with efforts centered on delivering business-value features rather than bug fixes.
