Sobre este Serviço
Are you looking for a senior AI engineer who can architect and deploy production-ready AI systems, not just connect an API?
You are in the right place!
I build AI agents, RAG systems, and LLM-powered SaaS applications for startups and growing businesses that need reliable, scalable AI infrastructure.
What I Deliver
- OpenAI Agents SDK Workflows: Production deployment of autonomous multi-agent networks utilizing the OpenAI Agents SDK for stateful tool-calling and intelligent workflow orchestration.
- Custom MCP Servers: Development of custom Model Context Protocol (MCP) servers to securely bridge your LLMs with local databases, enterprise APIs, and secure filesystems.
- Advanced RAG Systems: Retrieval-augmented generation pipelines powered by vector databases like Pinecone and pgvector for accurate, context-aware responses without hallucinations.
- AI Backend & Cloud Deployment: FastAPI microservices, secure APIs, and scalable deployment on AWS, GCP, or custom cloud infrastructure.
If you are building an AI product, automation system, or AI SaaS, let's architect it properly from day one.

I’m a Senior Backend & AI Engineer specializing in FastAPI, AWS, and production-grade LLM systems.
I build scalable APIs, AI agents, RAG pipelines, and automation tools using Python, LangChain, and vector databases—with a strong focus on reliability, performance, and security.
Engineering-first approach:
Clean architecture, cloud-native deployment, clear documentation, and maintainable code. If you’re building AI-powered infrastructure, I’ll help you ship it the right way—from MVP to production.

Perguntas frequentes
What exactly do you deliver in an AI agent or RAG project?
I build production ready AI systems tailored to your use case. This can include AI agent orchestration, RAG pipelines with vector databases, secure OpenAI or Claude integration, FastAPI backend APIs, and optional AWS or GCP deployment. No demos, only scalable real world systems.
Do you build small scripts or homework projects?
No. I focus on production ready AI systems for startups and businesses. If you need a quick script, assignment, or small bug fix, this gig may not be the right fit. I specialize in scalable AI agents, RAG pipelines, and real world AI applications.
What do you need from me before starting?
I need a clear description of your use case, target users, desired AI behavior, and preferred tech stack if any. If you are unsure, I can help define the architecture before development to ensure we build the right AI solution.
