M. Mart. - Fullstack Developer & AI Specialist

About Me

A journey of continuous learning and innovation

Professional Background

With 25+ years in the tech industry, I've evolved from a PHP developer at TV Canção Nova (2000-2003) to a fullstack specialist. As a public servant at São Paulo's Court of Justice for 16 years, I've mastered team leadership, horizontal and vertical hierarchies, and complex system development.

My journey includes private sector experience at Dimensional (2008-2012) and pivoting to mobile development in 2016, where I discovered my passion for React Native.

Recent Innovations

At DIGI4IND, I led frontend development for industrial IoT applications (4Ind and 4IndMap), handling everything from compilation to App Store/Google Play deployment.

Most recently, I created Decoralei, a comprehensive platform for public exam preparation, featuring AI-powered legislation analysis, intelligent flashcard generation, and advanced analytics—showcasing my expertise in full-stack development and machine learning integration.

DOTORA: Intelligent Legal Assistant

The latest project, dubbed "DOTORA," functions as a true legal assistant. It is a sophisticated AI platform built with Langchain/Langgraph, specifically designed to streamline daily operations and accelerate judicial response times.

Core Capabilities and Technology:

DOTORA leverages advanced AI techniques to deliver high-level legal document analysis and decision support:

Predictive Analysis: Utilizes both public and private LLMs (Large Language Models) for superior natural language processing.
Accelerated Decision-Making: Offers intelligent decision support, transforming raw data into actionable legal insights.
Multi-Model and LLM-Agnostic Orchestration: Public and private LLMs are combined in a coordinated manner to ensure both precision and security.
RAG (Retrieval-Augmented Generation): This guarantees that every analysis is grounded in relevant documents and databases, providing accurate and contextualized responses.
Fine-Tuning: The model is trained with TJSP (São Paulo Court of Justice) specific data to create an AI deeply specialized in Brazilian legal documentation.
