PROFILE
Jonni Madekivi
Jonni Madekivi developed and enhanced core features for the espoon-voltti/evaka repository, focusing on secure document archiving, authentication, and observability. He implemented device login alerts and signed cookie-based authentication, improving user security and trust. Jonni advanced document lifecycle management by integrating asynchronous archival workflows, SQL-based scheduling, and retention policy enforcement, using Kotlin and TypeScript for backend and frontend development. He strengthened system observability with OpenTelemetry instrumentation across Nginx and proxy layers, refining logging and audit trails for compliance and troubleshooting. His work demonstrated depth in API development, security, and configuration management, resulting in robust, maintainable, and compliant infrastructure.

Oct 1, 2025October 2025: Key features delivered, major fixes, and notable improvements across espoon-voltti/evaka. Observability strengthened with OpenTelemetry across Nginx and proxy layers: added an OTEL-enabled Nginx image, corrected OTEL endpoint configuration, consolidated OTEL settings, removed legacy trace IDs from logs, and enhanced span attributes (service name/version) for clearer tracing and faster troubleshooting. Staging validation enhanced by enabling Aromi integration and disabling Jamix in Espoo staging to expose and test the correct integration surface. Logging and auditing improved through restructuring audit metadata for recipients, consolidating filter logging, and simplifying how filters are recorded in MessageController. Configuration clarified by renaming startDate to syncRangeStart to better reflect the Koski data sync window. Major bug fixes include OTEL endpoint fixes, removal of non-needed trace-id logic, cleanup of outdated suppressions, and improvements to filter logging, all contributing to reduced noise and more reliable deployments. Overall impact: faster diagnosis, safer feature validation in staging, clearer data synchronization semantics, and demonstrated expertise in observability, configuration management, and logging architecture. Technologies/skills demonstrated: OpenTelemetry, Nginx integration, OTEL instrumentation, feature flagging, structured logging, and config refactoring for maintainability and performance.
