A solução integra Large Language Models (LLMs), via API Google Generative AI e framework Langchain, com técnicas avançadas de processamento de imagem (progressão de idade facial), utilizando uma interface gráfica intuitiva (PySide6) para orquestrar o processo. A ferramenta processa templates PDF e diversas fontes de dados (texto, CSV, XLSX, imagens) para gerar relatórios PDF finais, estilizados e multilíngues. Implementações Técnicas e Funcionalidades Chave: Geração de Conteúdo por IA: Utilização de LLMs (Google Gemini via Langchain) para síntese dinâmica de texto, adaptando o conteúdo com base em templates PDF, dados de entrada heterogêneos e configurações de estrutura definidas pelo usuário (títulos, seções, contextos específicos). Processamento de Imagem Avançado: Integração de modelos de visão computacional (baseados em PyTorch e Dlib) para análise e manipulação de imagens, especificamente para gerar projeções de progressão de idade facial. Os resultados visuais são incorporados diretamente no relatório PDF final. Interface Gráfica (GUI) e UX: Construção de uma interface desktop responsiva com PySide6 (Qt for Python), focada na usabilidade para carregamento de arquivos (templates, dados, imagens), configuração de parâmetros de geração (idioma, modelo, estrutura), visualização de prévias em HTML e monitoramento do progresso. Arquitetura Multilíngue: Sistema configurável para geração de relatórios em diversos idiomas, ajustando prompts e potencialmente o pós-processamento. Pipeline de Processamento de Dados: Implementação de rotinas para extração e normalização de dados de múltiplas fontes: Extração de texto de PDFs utilizando PyMuPDF, com fallback para OCR (EasyOCR) em documentos baseados em imagem. Parsing e conversão de dados tabulares de arquivos CSV e Excel (XLSX) usando Pandas. Processamento de entrada de texto livre e identificação de metadados de arquivos de imagem. Geração e Estilização de Documentos PDF: Conversão de conteúdo intermediário (Markdown) para PDF via WeasyPrint, aplicando estilos CSS customizáveis (cores, fontes, layout) e permitindo a incorporação de logos da empresa. Retrieval-Augmented Generation (RAG): Implementação de um sistema RAG opcional utilizando ChromaDB como vector store e Google Generative AI Embeddings. Permite consultar uma base de conhecimento interna para enriquecer o conteúdo gerado pela IA com informações contextuais relevantes, aumentando a precisão e a especificidade do relatório. Gerenciamento de Processamento Assíncrono: Utilização de QThreadPool e workers QRunnable para executar tarefas computacionalmente intensivas (chamadas à API do LLM, processamento de imagem, I/O de arquivos) em threads separadas, garantindo a fluidez e responsividade contínua da interface principal. Interação com API e Gerenciamento de Recursos: Implementação de estratégias de retry com backoff exponencial para lidar com erros transitórios da API (e.g., ResourceExhausted, ServiceUnavailable). Contagem de tokens de entrada (Tiktoken) e mecanismos de truncamento para operar dentro dos limites da API do LLM. Validação de Saída: Implementação de validadores (regex, lógica estrutural) para verificar a qualidade da saída do LLM, detectando problemas como placeholders não substituídos ou tabelas Markdown malformadas, e acionando retentativas de geração se necessário. Tecnologias Principais: Linguagem: Python IA & LLM: Google Generative AI API, Langchain, Google Embeddings Visão Computacional & Imagem: PyTorch, Dlib, Pillow, EasyOCR GUI: PySide6 (Qt for Python) Processamento de Dados: Pandas, PyMuPDF (fitz), Openpyxl, NumPy Geração de Documentos: WeasyPrint, Markdown Banco de Dados Vetorial: ChromaDB Utilitários: Tiktoken, Dotenv, Requests, Appdirs Impacto Técnico: O projeto demonstra proficiência na integração de sistemas de IA de ponta (linguagem e visão) com desenvolvimento de software tradicional (GUI, manipulação de arquivos). Supera desafios técnicos como o gerenciamento de processos assíncronos, a orquestração de múltiplas APIs e bibliotecas, o tratamento de diversos formatos de dados e a implementação de mecanismos de validação e resiliência em pipelines de IA. Resulta em uma ferramenta funcional end-to-end que resolve um problema prático de automação.","rating":4.8899999999999997,"ranking":78,"position":{"position":"gold","next":{"name":"Platinum","next":"hero","description":"Platinum es el quinto nivel de Workana. ¡Estás llegando a la cima!
