PROFILE
Jiri Charvat
Over thirteen months, Jiri Charvat engineered core observability and instrumentation features for the signalfx/splunk-otel-ios repository, focusing on mobile telemetry, session management, and cross-platform support. He delivered modules for startup tracking, session replay, and crash reporting, while modernizing the codebase through OpenTelemetry API upgrades and Objective-C/Swift interoperability. Jiri applied skills in Swift, Objective-C, and CI/CD to refactor agent initialization, implement JSON-based OTLP export, and streamline release workflows. His work addressed concurrency, data fidelity, and platform compatibility, resulting in robust, maintainable instrumentation for iOS, visionOS, and tvOS. The depth of his contributions improved reliability, release velocity, and analytics accuracy.

Feb 1, 2026February 2026 delivered critical stability, size optimization, and distribution readiness for signalfx/splunk-otel-ios. Key work included hardening SpanData against multithread access by using isolated copies and deep isolation tests, with updated docs and changelog. The OTLP export path was reworked to a JSON-based encoder to reduce binary size, including OTLP JSON models for traces/logs/metrics, updated exporters to JSON encoding, and cross-platform XCFramework support. A comprehensive XCFramework build system and distribution pipeline were established to package 27 modules across platforms, enhancing release reliability. Changelog traceability was improved by adding PR links and documentation enhancements.
