Worked on the vllm-project/vllm-omni repository to deliver a performance-focused feature for Qwen3-TTS, restoring cross-request batching in the Code2Wav module. This enhancement enabled the system to efficiently process multiple concurrent voice cloning requests, improving throughput and reducing latency under high concurrency. The solution was designed and implemented through an RFC-driven process, ensuring alignment with project standards and collaborative development practices. Leveraged skills in AI development, machine learning, and voice synthesis, utilizing Markdown and YAML for documentation and configuration. The work directly supported scalable, low-latency TTS services by reducing queuing times and improving overall system responsiveness.
