Keramet Kh built and enhanced backend APIs and observability tooling across Mojaloop and PM4ML repositories, focusing on reliability, maintainability, and data integrity. He delivered features such as the DfspWatcher for proactive DFSP reachability in pm4ml/connection-manager-api and a Hapi.js logging plugin with trace IDs in mojaloop/central-services-shared, using JavaScript, TypeScript, and Node.js. His work included refactoring for Axios-based HTTP clients, robust error handling, and improved CI/CD stability in pm4ml/mojaloop-payment-manager-management-api. By implementing configuration and dependency management, Keramet ensured accurate API contracts, reduced incident response times, and strengthened system resilience through comprehensive testing and metrics-driven monitoring.

October 2025: Stabilized CI pipeline and reinforced API contract for the Mojaloop Payment Manager API. Improvements focused on reliability, faster feedback, and smoother releases by tightening test infrastructure, API schema accuracy, and dependency compatibility.

May 2025 monthly delivery across two core APIs delivering improved observability, reliability, and state management. In pm4ml/connection-manager-api, the DfspWatcher feature was introduced to periodically ping DFSPs, with new database columns to track ping_status and ping_last_updated, plus a dedicated watcher service and observability metrics, enabling proactive reachability detection and faster remediation. In pm4ml/mojaloop-payment-manager-management-api, centralized logging and enhanced error handling were implemented to improve stability and debuggability, with updated logger usage and SDK-SC adjustments for detailed error responses. Additionally, the DFSP States Upload API was added using mcm-client 3.6.3 to enable more robust state management and reporting. These changes reduce incident MTTR, improve data quality, and strengthen overall system reliability and business confidence.
