Hi there, I'm Mateus Anacleto 👋

👨‍💻 Professional Summary

I am a Software Developer focused on Performance, Scalability, and Innovation. Currently working at CI&T, I specialize in architecting complex solutions and pioneering Agentic AI Workflows.

My core focus lies in bridging the gap between product vision and technical excellence, leveraging frontier models (GPT-5, Claude 4.5) and modern architectures (Microfrontends, Serverless) to deliver high-reliability applications.

💡 What I Bring to the Table

  • Frontier AI Engineering: Expert in building autonomous agents and RAG pipelines using MCP (Model Context Protocol) to reduce hallucination and automate complex workflows.
  • Complex Architecture: Proven track record in engineering financial engines (interest calculation, payments) and secure ecosystem integrations.
  • Scalable SaaS: Experience building multi-tenant platforms with Next.js and Nile DB, focusing on isolation and performance.

🏆 Featured Highlights

Here are a few high-impact challenges I've solved recently:

  • 🤖 Automated Market Intelligence Pipeline: Architected an ingestion engine using NestJS and Claude 4.5 Sonnet to parse unstructured social data into strict JSON with 99% precision, identifying high-potential business opportunities.
  • 💸 Financial Product Engineering: Led the implementation of a loan interest rate calculation engine, translating complex business rules into precise code for a major Fintech client.
  • 🚀 Microfrontend Migration: Increased squad autonomy and system scalability by implementing microfrontend architecture for a core banking application.
