AI Brazilian Tax Intelligence Platform Development

I’m building an **AI-powered Brazilian Tax Intelligence platform** designed to identify tax opportunities, risks, credits, and applicable tax strategies for companies.
The system will analyze company and tax data and cross-reference it with a structured legal database containing **Brazilian tax legislation, administrative rulings, court decisions (CARF, STJ, STF), tax authority guidance, tax regimes, and state-specific benefits**.
The platform should use AI to:
* Analyze company and tax data;
* Identify potential tax opportunities and risks;
* Match companies with applicable tax rules and precedents;
* Explain the reasoning behind each finding;
* Provide the legal sources supporting the analysis;
* Monitor changes in legislation and case law.
The architecture must support different **tax regimes (Simples Nacional, Lucro Presumido, Lucro Real and special regimes)** and multiple industries, such as fuel stations, healthcare, retail, manufacturing, importers, pharmacies, and others.
The goal is **not to create a generic ChatGPT for taxes**, but a reliable tax intelligence engine combining structured rules, legal databases, deterministic validation and LLMs/RAG.
I’m looking for a developer with strong experience in **Python/backend, LLMs, RAG, vector databases, data pipelines, APIs and AI agent architecture**. Experience with legal-tech, fintech or document intelligence would be a strong advantage.
