Vladinu contributed to the PublicisSapient/knowhow-api and knowhow-common repositories by building AI-powered features, scalable backend services, and KPI-driven analytics over four months. He implemented AI gateway integrations and sprint goal summarization endpoints using Java and Spring Boot, focusing on secure authentication and modular design. His work included developing end-to-end KPI services for defect SLA breaches, refactoring productivity gain algorithms, and enhancing monitoring with actuator endpoints. Vladinu applied API development, data modeling, and unit testing to improve automation, observability, and reporting. He also addressed code quality and maintainability through refactoring, bug fixes, and configuration management, ensuring reliable and extensible solutions.
September 2025: Strengthened productivity analytics and KPI-driven insights across knowhow-common and knowhow-api. Key outcomes include code-level refactor for the Productivity Gain algorithm, initial API integration with KPI trends and data caching, and KPI dashboard defect fixes with performance toggles to manage Iteration-based KPIs. A reversible Productivity Gain experiment in the common repository was postponed to stabilize the codebase while exploring a long-term approach. Business value delivered includes faster KPI data access, improved maintainability, and more reliable metrics dashboards.

Month 2025-08: Delivered end-to-end Defects Breached SLA KPI capabilities across knowhow-common and knowhow-api, enabling proactive defect SLA monitoring and richer reporting. In knowhow-common, completed initial development for tracking defects breached SLA KPIs (KPI 195), extended the data model for breach analysis, added new fields and history tracking, and refactored field mappings for clarity. In knowhow-api, delivered a full KPI service to calculate and report defects that miss SLA windows, including field mappings and enums, data formatting, drill-down/hover data, and Excel reporting, along with refactors and test updates to improve reliability and maintainability. Addressed code-quality concerns (Sonar fixes), resolved unit-test failures, and handled edge cases (null hover values).
