Luciana Ferreira

I am a Machine Learning / AI Engineer who delivers end-to-end production systems, spanning data engineering, modeling, and MLOps. I specialize in building reliable pipelines and production deployments that turn raw signals into operational insights.

Recently I delivered Databricks-based airport analytics for Fraport to measure passenger presence from Wi‑Fi, an audio-to-insight LLM pipeline (Whisper → enrichment → GPT-4o-mini) that drafts personalized sales follow-ups, and RondaPress, a newsroom intelligence engine that scrapes and ranks content with LLM headline generation.

In prior roles I shipped regulated conversational AI solutions for major banks and built pre-LLM assistants, combining UX design, NLU tuning, and compliance-aware engineering. I also founded a developer education nonprofit, secured a USD 25k grant, grew a 150+ developer community, and translated a technical book for O’Reilly.

Technically, I work with Python, SQL/Spark/Databricks, FastAPI, Docker, CI/CD, Cloudflare Tunnels, AWS, and LLM/ASR/TTS tools (OpenAI, Whisper, ElevenLabs). I operate effectively as an individual contributor or tech lead, focused on shipping robust, scalable AI products.
