Welcome to my profile! Looking for a Full Stack & AI Engineer who can build production-grade software and wire real AI into it — not just a demo? You're in the right place. I build full-stack applications and AI-driven systems that automate workflows, streamline operations, and turn ideas into scalable, market-ready products. Think of it as having a senior engineer who can own your product end-to-end: backend, frontend, cloud infrastructure, and the AI layer that makes it smart. I help startups and businesses ship practical software — SaaS platforms, AI agents, chatbots, workflow automation, and RAG-based applications — with the same rigor you'd expect from a core engineering hire, not a freelancer bolting on an API. ✅ What I Build Full-stack SaaS platforms and internal business tools, built from the ground up Multi-tenant architectures and cloud-native backend systems AI Agents that complete tasks, analyze information, and assist teams LLM-powered applications using OpenAI, Claude, and open-source models Retrieval-Augmented Generation (RAG) systems with vector databases AI workflow automation using n8n, Make, Zapier, and custom integrations Intelligent data pipelines and automation systems ✅ My Technical Expertise 🟢 Backend & Data ✓ Python, FastAPI ✓ Node.js, NestJS ✓ PostgreSQL, Redis, Supabase ✓ REST APIs and third-party integrations ✓ Multi-tenant system design ✓ Data processing pipelines 🟢 Frontend & Full-Stack ✓ React, Next.js, TypeScript ✓ Modern SaaS application development ✓ AI dashboards and business platforms 🟢 AI & Automation ✓ OpenAI API, Claude API, Llama models ✓ AI Agents & Multi-Agent Systems ✓ RAG pipelines, vector databases ✓ Prompt engineering ✓ AI workflow orchestration ✓ n8n, Make, Zapier automation 🟢 Cloud & Deployment ✓ AWS, Docker, Kubernetes ✓ Cloud-native architecture ✓ Scalable backend systems ✓ Production deployment and optimization ✅ Problems I Help Solve ✓ Products that need a single engineer who can own the full stack ✓ Manual business processes that waste time ✓ Teams overwhelmed by repetitive tasks ✓ Information trapped across multiple systems ✓ Customer support and sales processes that need automation ✓ AI ideas that need a reliable technical implementation ✓ Existing AI prototypes that need to become production systems ✅ Why Clients Work With Me I treat every project — full-stack or AI — as a software engineering problem, not an experiment. You get: ✓ Scalable architecture instead of a quick prototype ✓ Clean, maintainable code across the whole stack ✓ Reliable AI workflows designed for real usage ✓ Clear communication throughout development ✓ Solutions focused on business impact, not unnecessary complexity If you already have a clear vision, I can turn it into a fully functional product with precision and attention to detail. If you only have an idea, that's fine too — we can shape it into something practical together. Hope to hear you back. Regards, Gustavo…Welcome to my profile!
