Dusan contributed to the wireapp/wire-avs repository, focusing on real-time communication features and stability improvements over a three-month period. He developed and documented an audio recording API, enhanced WebRTC network statistics reporting, and improved video call reliability under variable network conditions. Using C, C++, and JavaScript, Dusan refactored backend components for clarity and efficiency, updated Android build systems, and optimized performance through code cleanup and state management. He also addressed runtime stability by disabling problematic restart logic and maintained test suite compatibility. His work demonstrated depth in embedded systems, network programming, and test-driven development, resulting in more robust, maintainable releases.

September 2025 (wire-avs) focused on stability and test integrity. Delivered two prioritized changes: (1) disabled automatic ecall restart on activation to improve runtime stability, preventing restart attempts after data channel establishment; (2) updated test suite to align wcall_start and init_ccall signatures by adding the required boolean argument, preserving test reliability. Commit references: 9abbc09fc494075d5bdf5deb26531a5776f31b92; a542988bf934d0e36ed560d8de90f6dbeb1a251a. Business impact includes reduced restart-induced instability, improved user runtime reliability, and preserved test suite validity enabling safer releases. Technologies/skills demonstrated include C/C++, embedded telephony components, API compatibility, test-driven development, and version control discipline.
