Senior Ai Engineer/Software Engineer

I’m a Senior Software Engineer and AI Engineer with experience building and deploying production-grade AI-powered systems. Currently, I work at an AI-focused startup where I design and deliver end-to-end intelligent applications — from architecture to deployment and monitoring 
CV - Gabriel Barreto EN.

I have hands-on experience integrating LLMs and AI workflows using tools like n8n, Flowise, FastAPI, and Node.js (TypeScript), deploying scalable services with Docker and Kubernetes, and monitoring production systems with Datadog and Grafana 
CV - Gabriel Barreto EN. I focus on building reliable, high-performance backend systems with strong architectural foundations.

Previously, I worked as a Full Stack and Backend Developer building enterprise web applications with Java (Spring Boot), .NET, Angular, and distributed systems involving Kafka and automation pipelines 
CV - Gabriel Barreto EN.

In parallel, I developed an academic project focused on violence detection using CNN/LSTM models for drone surveillance 
CV - Gabriel Barreto EN, reinforcing my applied machine learning background.

I’m currently looking for:

  • Senior AI Engineer roles (LLM systems, AI agents, RAG, production AI infrastructure)
  • Senior Software Engineer / Backend Engineer roles (distributed systems, cloud-native architecture, scalable APIs)
  • Web3 / Blockchain engineering opportunities (smart contracts, ERC standards, decentralized systems)

I’m open to challenging problems, high-impact teams, and global opportunities where I can contribute at a senior level while continuing to grow technically.
