Building platform for conversational AI for phone calls, orchestrating LLMs, transcription models, and voice synthesis models. Joined as one of the first technical hires, focusing on core technical challenges in model performance, conversation latency, system scalability, and reliability. Notably focusing on fine-tuning models (customer agents, voicemail detection), ML lifecycle pipelines (data collection/cleaning, training infra, model evaluation suites), observability (Sentry integration, system logging), and core features (integration of model providers like Anthropic, model fallback mechanisms, interruption handling, etc.). Led internal and customer projects, designed our engineering on-call process, helped with candidate interviews and hiring, and contributed to open-source repo (https://github.com/vocodedev/vocode-core).
