During August 2025, David Mburu developed a modular rule engine for the eugenp/tutorials repository, focusing on actor-based architecture using Akka and Java. He designed the system to process rules and actions through discrete actors, supporting scalable and maintainable rule evaluation. David implemented comprehensive unit tests to ensure correct rule execution and integrated the feature into the main branch via a structured Git workflow. His approach emphasized future extensibility, enabling straightforward expansion of rule sets and automation capabilities. The work demonstrated depth in actor-based programming and careful attention to code quality, laying a foundation for robust, rule-driven decision automation.
