Message

At LizzyAI, I’m the first engineer and hands-on technical lead, building the core product while growing the engineering team from 1 to 8. I’ve shipped full-stack features across a FastAPI/Python backend, React/Next.js frontend, PostgreSQL, and AWS, and built an LLM-powered voice interview engine with candidate scoring and CV-screening pipelines.

Across B2B SaaS, workflow-heavy applications, APIs, and integrations, I’ve taken products from requirements and architecture through deployment and iteration. Earlier work includes developing backend services for ConquestEvents.net at SweatWorks and contributing to Puedo.com.ar, a lending platform, at Summit SA.
