Apr 1, 2026April 2026 Ukama/ukama monthly summary focusing on business value and technical achievements. Key features delivered include the Ukama Agent Enhancement with SimFactoryClient integration, which replaces the dummy factory dependency, enabling enhanced agent functionality. This involved dependency updates and lint/build issue cleanups for a cleaner codebase. Major bugs fixed include the removal of the default NodeFeederRoutingKey and related unit test fixes to stabilize routing behavior in ukama-agent/asr and related hooks. These fixes improve routing correctness and test reliability under CI. Overall, the month delivered stronger agent capabilities, cleaner maintenance surfaces, and more reliable simulation workflows, contributing to lower production risk and faster feature delivery. Technologies and skills demonstrated include Go module/dependency management, lint/build hygiene, unit testing, hooks, routing logic, and integration with external services (SimFactoryClient).
