Ivan contributed to the JessicaSista/PIS-2025 repository by building end-to-end Sonda API integration with a device management UI, enabling authenticated device listing and structured data access. He implemented role-based access control and JWT authentication, strengthening security and permissions. Using C#, ASP.NET Core, and Entity Framework Core, Ivan designed cohesive data models for datasets and visualizations, introduced sensor data input, and integrated dashboards with ApexCharts. He optimized device data retrieval through consolidated API calls and SQL join improvements, stabilized reporting features, and refactored backend components. His work established scalable foundations for analytics, improved maintainability, and enhanced data reliability across the platform.

For 2025-10, delivered a set of foundational enhancements to data visualization, data access, and reporting, while stabilizing data retrieval through SQL join optimizations and device-reading fixes. This cycle focused on improving data discovery, reliability, and time-to-insight across analytics and operational dashboards, and establishing scalable scaffolding for future data evolution in the PIS-2025 repository.

September 2025 for JessicaSista/PIS-2025 delivered end-to-end Sonda API integration with the Device Management UI (SondaTest), enabling authenticated device listing, structured data, and new API endpoints across Sonda-related components. Implemented RBAC and JWT-based authentication with security migrations to strengthen access control and permissions. Added a cohesive datasets and visualizations data model and API, including dataset groups, migrations, and seed data to accelerate analytics deployment. Added Sensor Data Input, employee management, dashboards (ApexCharts integration), and backend EF Core refactor to improve data handling and UX. Optimized device data retrieval through consolidated API calls and improved client-side processing, and performed code cleanup/removal of unused entities to resolve build issues and improve maintainability.
