AI Engineer | Agents, Automation & Integrations

Cover image for I'm currently building Omnicrm.chat (http://OmniCRM.chat).

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.

Cover image for AI-Powered OCR Pipeline for Document Processing

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

Cover image for Intelligent AI Agent for Business Automation

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.

Cover image for Transform a Local Bike Shop with a Modern Digital Platform

🚲 What if a small neighborhood bike shop had a modern digital experience? For the #GiveItAGlow challenge by @Base44, I chose Uncle's Bike, a local repair shop in Cambuci, São Paulo, Brazil. Before: customers relied on Google Maps, phone calls, and WhatsApp for everything. After: I created VELO·WORKS—a modern platform with online booking, AI assistance, automations, and a workshop dashboard to simplify daily operations and improve the customer experience. Watch the transformation and try the project here: 👉 https://velo-works.base44.app #GiveItAGlow

I used Google Stitch to generate and evolve the interface with prompts and visual references, exploring motion, hover effects and a UI that feels alive. 🔗 Project: https://stitch.withgoogle.com/preview/9399905294660220176?node-id=f2d2e066aa814c768ee39d333e9008cf @stitchbygoogle #GoogleStitch #Cyberpunk #GameUI #WebDesign
