Ajay Sehwal developed and delivered external self-pay invoice recognition for the getAlby/hub repository, focusing on backend development using Go and Lightning Network technologies. He implemented a system that automatically detects and processes invoices generated outside of LND by matching incoming transactions with the same payment hash, which reduces manual reconciliation and streamlines cross-system settlements. Ajay updated the test suite to cover a range of edge cases, enhancing the robustness and reliability of the new feature. His work improved cash-flow visibility and operational consistency, enabling seamless cross-system invoicing and providing traceability for future development and maintenance within the codebase.
