At GX Advogados, I’m the sole technical owner and Tech Lead of an AI-driven legal platform used daily by lawyers. I designed and built GX Portal AI, which classifies official court gazette publications with structured LLM output and lets the legal team confirm decisions in one click.
I built the firm’s legal RAG assistant to ground answers in pleadings, rulings, and case documents, with source citations. I orchestrated retrieval and review flows with LangChain and LangGraph, and changes pass evaluation against the firm’s expert-labeled ground truth before production.
I also built the PJe Agent, which authenticates to the labor court portal with a digital certificate and 2FA, collects case updates, and uses an LLM to summarize and rank their severity. The platform combines LLM interpretation with deterministic deadline calculation, and includes human review, audit trails, and security controls validated by a pentest.
At Globality IT Consulting, I maintained enterprise API integrations with a security focus and automated log analysis and incident triage routines in Python, including LLM-based ticket-classification prototypes. My work also spans production SaaS and internal systems, application security, and full-stack platforms.
