Juan Camilo Martinez
Applied AI Engineer

I build audio/speech ML pipelines and multi-agent systems. Each project below explains what I built and why.

Get in touch

Audio/Speech ML

Production pipelines with Whisper, wav2vec2, Parselmouth, and Silero VAD. Pronunciation scoring, prosody analysis, phoneme alignment.

Multi-Agent Systems

Agent orchestration with LangGraph, Redis event bus, guardrails, health preflight, and observability dashboards.

Business-Aware AI

Unit economics at the architecture stage. Pricing models, evaluation systems, and cost-per-inference thinking from day one.

Featured Work

The two systems that define my engineering identity.
