Architecting AI
For Production.

I design and deploy scalable LLM architectures, autonomous multi-agent workflows, and resilient backend systems. Hype-free engineering for real-world impact.

Breno Cavalcante - AI Engineer

Engineering Philosophy

I am a GenAI Engineer with a background in Computer Science and Software Engineering, currently focused on designing and deploying scalable AI systems powered by LLMs, RAG architectures, agent orchestration frameworks, and MCPs.

Bridging the gap between traditional robust software architecture and next-generation artificial intelligence paradigms. No hype, just production-grade engineering.

Impact Cases

The impact showcase. Focus on structural problem-solving and scalable system design over mere syntax.

Redator AI — ENEM Essay Correction

Python FastAPI React Tesseract LangChain Gemini
Source

// PROBLEM

Students often lack fast, objective feedback on ENEM essays; manual grading is slow and inconsistent.

// ARCHITECTURE

React frontend for image upload, FastAPI backend for preprocessing (OpenCV) and Tesseract OCR; LangChain + Gemini evaluates text against ENEM criteria and stores results in PostgreSQL.

// IMPACT

Automated, rubric-based scoring and actionable feedback reduce turnaround time and provide consistent evaluations at scale.

WhatsApp AI Agent — Barber Shops

Python LangChain FastAPI ChromaDB Docker
Source

// PROBLEM

Small businesses need fast, 24/7 customer support on WhatsApp; manual responses scale poorly and lack personalization.

// ARCHITECTURE

WAHA webhook → FastAPI processes messages → LangChain + RAG retrieves docs from ChromaDB → LLM composes replies; deployed in Docker for scalability.

// IMPACT

Delivers instant, context-aware answers, increases booking rates and reduces support time by automating routine conversations.
