Adrian Perciun contributed to the CPS-Innovation/Polaris repository by delivering eight features and resolving critical bugs over four months, focusing on backend modernization and reliability. He upgraded Polaris to .NET 8, integrated Azure Functions Isolated Worker, and standardized JSON serialization with System.Text.Json, improving maintainability and performance. Adrian enhanced observability through enriched telemetry and request tracing, refactored durable entity state management for data consistency, and modernized authentication header handling to resolve cross-system issues. His work leveraged C#, TypeScript, and Azure services, demonstrating depth in API development, dependency injection, and code refactoring, resulting in a more robust and scalable backend architecture.

Feb 1, 2025February 2025 accomplishments for CPS-Innovation/Polaris: Delivered three key improvements that enhance diagram support, document lifecycle management, and system architecture. Key items include: - Aspose Visio Diagram Support and Code Modernization: Adds Visio diagram support via Aspose, aligns Application Insights with the WMA DDEI instance, and modernizes code using newer C# syntax to improve clarity. Notable commit: 55d0e3f4a724b4f3b55c0a9126b2e82a82e87d1b (FCT2-4796, FCT2-4794) addressing build warnings and AppInsights config (#1609). - ToggleIsUnusedDocument API in Polaris Gateway: New endpoint to mark documents as unused; integrates with the DDEI client; returns OK on success or BadRequest on failure. Notable commit: c0a5ccb691634db30b49703a85c7a365965315bd (28700: Added ToggleIsUnusedDocument endpoint (#1592)). - Coordinator Service Architecture Modernization and State Storage: Refactors the coordinator service to use a new state storage service (replacing Durable Entities); adds activities/services for case/document state management; updates blob storage paths and tests. Notable commit: ee5fc2b8790bdd2019a59d49ef8bbdf8309f8669 (Fix Search for Large Cases (#1600)).

Jan 1, 2025Month: 2025-01 | CPS-Innovation/Polaris Concise monthly summary focusing on key achievements, business value, and technical excellence across Polaris services. Overview: - Deliverables prioritized observability, modernized tech stack, and data correctness to enable faster troubleshooting, higher reliability, and scalable operations for customer-facing workloads. Key features delivered: - Polaris Observability Enhancements: improved telemetry and error visibility by disabling adaptive sampling, enriching request telemetry, and fixing non-HTTP trigger handling. - .NET 8 Upgrade and Isolated-Process Coordinator: upgraded runtime to .NET 8, implemented isolated-process pattern for the coordinator, and enhanced telemetry naming for clearer insights. - System.Text.Json Migration & Request Tracing: standardized JSON serialization using System.Text.Json across services and improved request tracing by introducing Correlation IDs. - CaseDurableEntity Refactor: refactored to use separate state objects for case status and document lists; updated services and tests to ensure data consistency and better maintainability. Major bugs fixed: - Middleware fix for non-HTTP triggered functions to ensure correct invocation and telemetry (#1574). - Serialization bug fixed by migrating document handling to System.Text.Json (fixes for serialized document modifications) (#1588, #1589). - Large-case search issue resolved following CaseDurableEntity refactor (#1591). Overall impact and accomplishments: - Significantly improved observability, traceability, and reliability across Polaris services, enabling faster root-cause analysis and reducing mean time to resolution. - Modernized tech stack with .NET 8 and System.Text.Json, improving performance and maintainability. - Stronger data consistency guarantees and scalable state management for durable entities, supporting growth in large-case workloads. Technologies/skills demonstrated: - .NET 8, isolated-process coordination, System.Text.Json, Correlation IDs, enhanced telemetry naming, request tracing - Middleware resilience for diverse trigger types, durable entity design and data consistency strategies, incremental refactoring with test coverage Business value: - Faster issue detection and resolution, higher service reliability, and smoother onboarding for new features due to standardized serialization and improved observability.
