AI Engineer | Agents, Automation & Integrations

Most OCR systems stop at text extraction. The real value starts after the document is read. In this project, I built an AI-powered OCR pipeline capable of extracting text from invoices, contracts, reports, and forms while also classifying the document type and identifying key information automatically. Instead of returning raw text only, the system structures the data into usable outputs for automation workflows, CRMs, ERPs, and AI agents. This reduces manual processing time and makes documents immediately actionable inside business operations. The stack combines OCR engines with LLM-based processing for contextual understanding, keyword extraction, and intelligent classification. The result is a more reliable document processing flow that can integrate directly with APIs, databases, and automation systems. This is where AI engineering becomes practical: transforming unstructured files into structured business data at scale

I'm currently building Omnicrm.chat (http://OmniCRM.chat). A CRM and multichannel communication platform designed to keep customer conversations, sales opportunities, and operational workflows in a single workspace. Most teams still manage WhatsApp, Telegram, email, proposals, tasks, and customer records across multiple disconnected tools. The result is lost context, duplicated work, and a fragmented customer experience. With OmniCRM.chat (http://OmniCRM.chat), conversations can evolve into opportunities, projects, and tasks without manual data entry. The goal is to connect communication, CRM, and execution into one platform, while creating a foundation for future AI-driven automation across the entire customer lifecycle.

Most businesses are already experimenting with AI — but very few are using it the right way. A generic chatbot is not enough. What actually drives value is a custom AI agent built around your workflows, capable of calling APIs, automating decisions, and integrating directly with your systems. This is where AI stops being a demo and starts becoming infrastructure. With the right architecture, your AI can handle operations, reduce manual work, and scale processes without increasing costs — from customer support to internal tools, data processing, and beyond. If you're thinking about building a real AI solution tailored to your business, let’s talk.

Seamless creating of PWA and published to Play Store! A django project using no framework of javascript, was successfully transitioned to PWA! The behaviour is different between browser and PWA, so needing to modify nothing on the frontend was a great achievment!

Stuna is a specialized platform built to organize, connect, and empower the vibrant and rapidly growing manga-collecting community in Brazil. Unlike traditional markets, Brazilian manga culture is deeply shaped by diversity: from regional publishing differences to unique release schedules, limited-edition prints, and small specialized retailers spread across the country. Collectors often struggle with fragmented availability, inconsistent stock, and the difficulty of finding specific volumes, especially from older or niche series. Stuna solves this by unifying collectors, local comic shops, and distributors into a single intelligent ecosystem. Through demand tracking, pre-order management, and community-driven inventory insights, Stuna makes collecting Brazilian manga easier, more organized, and more accessible.
