A two-phase arc — legal-document research at Unifor / NCDIA, then applied retrieval, precedent, and prediction systems at FI Group. The chapter that taught João how to work in structured, high-context, high-precision domains.

Period
2023–2024 (research) · 2025–2026 (applied)
Significance
A foundational thread in João's trajectory: research discipline, structured reasoning, and domain-specific AI system design, carried from academic work into applied internal-AI infrastructure.
Why it matters
Shows João's ability to move from academic investigation to applied AI systems in high-context domains where grounding, structure, and precision matter far more than generic model outputs.
Story arc
How this chapter unfolded.
- 01
Research foundation
Learning to structure complex legal information.
João's early legal-AI work at Unifor / NCDIA focused on classification, hybrid retrieval, and the discipline of turning messy legal material into structured, machine-readable problems. The rigor came first; the systems came later.
- 02
Method
Precision mattered more than generic generation.
The work trained the instinct that later became central to João's AI systems: outputs need structure, traceability, and evaluation — especially in high-context domains like legal, policy, and business workflows. PromptBreeder + DSPy beat expert-crafted prompts and LegalBERT-pt; the lesson was that careful evaluation wins over confident-sounding output.
- 03
Continuation
From classification to grounded intelligence.
More than a year later, João's FI Group work extended that foundation into retrieval, precedent analysis, prediction workflows, and agentic systems for domain-specific decision support. Same theme; different chapter; different employer. The thread is continuity, not timeline collapse.
Curated media
A few moments that tell the story.

The research environment at Unifor — where the legal-AI work began with classification, hybrid retrieval, and prompt-optimization research backed by FUNCAP.

Academic context tied to the NCDIA group — the discipline of high-context, high-precision AI work that became this chapter's foundation.

Phase two — the FI Group Lei do Bem Precedent Analysis Agent (Oct/Nov 2025 – present). Agent workflow, RAG microservice, vector store, LLM, source-cited answers. The applied output of the research instinct on a much larger surface.

Phase two — the FI Group Technical Intelligence Prediction Agent. Extraction, embeddings, ML artifacts, structured advisory output. Decision-support intelligence, not loose chatbot answers.
