Luiz Carlos

AI Engineer · Senior Specialist

I build production LLM systems, AI agents and RAG pipelines, and the automation around them. I lead AI and automation at BWG in São Paulo. Before that, I built 20+ production AI agents at Auria AI that handled 3,000+ security incidents a day.

About

Engineering at the edge of data and AI.

I’m most useful where models, backend systems, and real business processes meet.

At BWG, I lead AI and automation for a corporate benefits company, from process discovery to deployment and adoption, reporting directly to the CEO. Each step of a workflow gets the right tool: an API integration, deterministic automation, LLM assistance, or human review.

Before that, at Auria AI, I built 20+ production AI agents in an incident-response pipeline handling 3,000+ B2B security incidents a day, along with the PostgreSQL data layer, BI dashboards, and on-call alerting around them.

Earlier, I migrated a legacy Ruby on Rails platform to Kotlin at IME-USP. I hold a B.Sc. in Computer Science from the University of São Paulo.

Experience

Building, migrating, and leading.

Applied AI and production engineering, built on a foundation in research and technical leadership.

AI Engineer · Senior Specialist

BWG · HR Technology & Corporate Benefits · São Paulo, Brazil

Lead AI and automation initiatives, from process discovery to deployment and adoption, reporting directly to the CEO.
Map business workflows step by step, deciding where each step needs an API integration, deterministic automation, LLM assistance, or human review, with baseline metrics to measure results.
Built an internal platform that automates quoting and document workflows; the team adopted it after the first demo.
Built an LLM document-extraction pipeline in which every extracted field links back to its source and missing data is flagged instead of guessed.
Deploy and operate the platform on Kubernetes, with CI/CD pipelines and automated backups.

Backend Software Engineer

Auria AI · São Paulo, Brazil

Built and maintained 20+ Python AI agents in the production incident-response pipeline, handling summarization, insight extraction, and automated decision-making for 3,000+ B2B security incidents per day.
Bootstrapped and maintained the PostgreSQL/SQLAlchemy data layer across 36 production tables, shipping backend features end to end across multiple FastAPI services.
Built Auria’s Metabase BI from scratch, including operational dashboards, KPI analyses, and threshold-based alerts used daily by incident-response leadership.
Designed and shipped an on-call alerting bot that calls the responsible engineers through Twilio with AI-generated incident summaries, reducing overnight outage detection from 8+ hours to near-immediate.

Selected work across meeting intelligence and retrieval-augmented generation.

Open source, since 2026

Memoir — AI meeting knowledge workspace.

An open-source full-stack app that turns meeting transcripts into searchable summaries, decisions, action items, participant profiles, and structured transcript segments. It detects Zoom and Google Meet formats automatically, with a Gemini fallback for messy or unsupported ones, and Pytest coverage protects parsing and core workflows.
