Backend IA PDF, entrega texto e áudio via WhatsApp

@Herculesz

Hi I can build an AI-powered backend that autonomously reads your recurring technical PDFs, extracts complex tables and specification fields without losing critical formatting, and normalizes everything into a well-structured SQL database optimized for natural-language queries. A key technical challenge is preserving table structure and detailed specification fields, and I solve this through layout-aware parsing, table reconstruction logic, and validation checks before saving any record. Another challenge is enabling real-time WhatsApp queries, which I address by designing a semantic query layer that interprets questions like “What is the maximum pressure of component X?” and retrieves the correct value with its source reference. I have experience integrating the official WhatsApp Cloud API/Twilio, building document-processing pipelines, and deploying scalable backends with clean documentation. The final system will allow you to send a PDF, store every structured field, and ask questions from WhatsApp with accurate, source-cited answers in seconds. This creates a reliable, automated end-to-end workflow for your technical documentation. Thanks, Hercules

Hello, I’m excited about the opportunity to contribute to your project. With strong experience in Python, extração estruturada de PDFs (incluindo tabelas complexas) e pipelines de dados com SQL, eu posso construir um backend autônomo que processa seus documentos, normaliza os campos em um banco relacional bem indexado e responde perguntas via WhatsApp com respostas rápidas e citando a fonte no próprio PDF. I’ll tailor the pipeline to preserve formatação crítica, combinar extração de tabelas e texto descritivo com validações de qualidade, e integrar com a API oficial do WhatsApp (Twilio ou Cloud API) para receber a pergunta, consultar o banco e retornar a resposta em segundos. You can expect clear communication, fast turnaround, and a clean, scalable deployment with documentação objetiva para você manter e evoluir o sistema com segurança. Best regards, Juan

I can build this end to end: a backend that ingests technical PDFs, extracts tables and specs accurately, stores them in a structured SQL database, and lets you query everything through WhatsApp with precise answers and source references. Approach Reliable extraction is the core. I use a hybrid pipeline: direct structured parsing for text based PDFs and OCR plus table reconstruction for scanned files. Tables, paragraphs, and specs are preserved with page and cell level references so nothing critical is lost. Database design SQL schema structured for fast natural language queries. Documents, pages, tables, rows, and normalized specification fields are indexed so questions like “max pressure of component X” return in seconds with citation of page and table. WhatsApp integration Using WhatsApp Cloud API or Twilio. You send a PDF, it gets processed automatically. When you ask a question in WhatsApp, the system retrieves the answer from the database and returns it with the exact source. Stack Python processing pipeline, PostgreSQL, async workers, secure file storage, scalable cloud deployment with documentation. If you share sample PDFs and expected weekly volume, I can define exact milestones and finalize cost.

Olá, Analisei seus requisitos e entendi que você precisa de um backend de IA escalável para ingerir automaticamente PDFs técnicos (texto + áudio convertido), extrair tabelas e especificações complexas sem perda de formatação, armazená-los em um banco de dados SQL bem estruturado e responder a consultas em linguagem natural via WhatsApp usando a API oficial. Tenho mais de 10 anos de experiência e entregarei um sistema completo com: Pipeline de ingestão automática de PDFs Extração avançada de tabelas, preservando a estrutura (células mescladas, cabeçalhos e valores de várias linhas) Modelagem SQL robusta com índices e relacionamentos otimizados RAG (Retrieval Augmented Generation) para respostas precisas com citação da fonte Integração com a API oficial do WhatsApp (Twilio ou WhatsApp Cloud API) para consultas em tempo real Arquitetura escalável (Docker, pronta para Kubernetes) Documentação completa + código-fonte Critérios atendidos: Extração sem perda de formatação Respostas rápidas e contextualizadas Implantação e testes em produção com seus PDFs Trabalharei com metodologia ágil, entregando de forma iterativa e fornecendo suporte contínuo. Tenho algumas perguntas sobre o provedor do WhatsApp, o volume de PDFs e a necessidade de OCR. Aguardo sua resposta positiva. Obrigado

Hello client, I can develop an artificial intelligence backend that will autonomously read recurring technical PDFs, identify complex tables, descriptive text and technical specifications, save everything in a well structured SQL database and then finally make this information available in a WhatsApp conversation. By choosing me, you are choosing a partner that not only speaks, but delivers results that speak for themselves. Let's discuss your project requirements in more detail over private message. Looking forward to contributing to your project success, Fahad.

Olá, tudo bem? Sou Machine Learning Engineer com 8+ anos em produção, especializado em NLP, extração de dados e pipelines escaláveis. Já construí sistemas que leem PDFs técnicos complexos, preservam tabelas críticas e normalizam tudo em SQL para busca em linguagem natural. Em um projeto industrial, resolvi falhas de extração combinando parsing estruturado e modelos NLP, entregando respostas em tempo real via WhatsApp API com fonte rastreável.

I specialize in building robust, high-performance Retrieval-Augmented Generation (RAG) backends, having recently implemented a similar solution integrating detailed financial reports with automated WhatsApp delivery. Your need for an autonomous AI to process technical PDFs and deliver text/audio summaries via WhatsApp aligns perfectly with my deep expertise in LLM orchestration, document parsing, and third-party API integration. I propose a modular Python backend utilizing LangChain and LlamaIndex for robust PDF parsing, chunking, and embedding. We will use a dedicated vector database (e.g., Pinecone or Chroma) for high-speed RAG queries against the technical documents, ensuring contextual accuracy. Summarization will be fine-tuned via precise prompt engineering (using GPT-3.5/4 Turbo), followed by integration with AWS Polly or Google TTS for generating the audio file output. Delivery will then be handled seamlessly via the official WhatsApp Business API or Twilio integration, ensuring reliable message delivery. To scope this accurately: Are the technical PDFs standardized in format (tables vs. pure text), or do we require advanced visual OCR handling? Also, what is your target latency requirement for the audio generation? Let’s schedule a brief 10-minute chat to quickly align on the specific LLM strategy and infrastructure for the most precise and efficient execution roadmap.
