I design AI agents, RAG architectures and ETL pipelines that remove manual work from real businesses. Five years of remote delivery across US and Brazilian teams.
I'm a Computer Engineering graduate from UFRGS — a top-5 ranked university in Latin America — working remotely from Florianópolis, Brazil. Over five years I've moved from full-stack product work into data engineering, and then into AI: agents, RAG pipelines and the automation plumbing that connects them to real business systems.
Today I build AI agents on n8n and HubSpot integrations for US clients, run WhatsApp-based agents for ten businesses, and share what I learn on YouTube. I work async, document everything, and ship independently across time zones.
Led end-to-end HubSpot CRM implementations for multiple US clients: requirements, data modeling, secure migrations and automated two-way integrations keeping leads, contacts, companies and deals in real-time sync.
Identified AI gaps in an accountant system and built agent workflows with RAG and prompt engineering. Documented 80+ Airtable and Zapier automations and migrated them to Supabase + n8n.
Built and maintain AI agents for 10 business clients, each on WhatsApp via Evolution API. Engineered prompts that cut token spend and loaded embeddings into Supabase vector stores for faster RAG retrieval.
Built scalable ETL pipelines with Python, PostgreSQL and Elasticsearch, improving data accuracy 30%. Automated ingestion in Airflow — 25 hours saved per month — and shipped a Gemini-powered FastAPI microservice that cut processing time 40%.
Delivered 15+ features in Vue.js, Node.js and TypeScript, lifting engagement 40%. Acted as Scrum Master and migrated the site to Nuxt.js and Tailwind, cutting load time 35%.
Shipped 20+ features across React, Django and PostgreSQL, halving API response time. Built the tenant maintenance-request page in a system integrated with real-estate agencies — making it easier for renters to get things fixed.
Worked with four senior developers on 10+ features and performance fixes for Laravel systems — including Burger King internal systems — contributing to a 30% reduction in critical errors.

Placeholders below — replace each with a real screenshot, an architecture diagram and the outcome numbers.
Ten business clients, each with its own agent, tools and knowledge base — one shared n8n and Supabase backbone.
A FastAPI service with a single structured prompt that turns unstructured news pages into analytics-ready JSON.
Documented and rebuilt a sprawl of Airtable and Zapier flows on Supabase and n8n, cutting cost and fragility.
I publish real-world AI agent and automation walkthroughs on @FernandoUtzig. Drop the video IDs and these cards become live embeds.
Placeholder quotes — send me two LinkedIn recommendations and I'll swap them in verbatim.
Placeholder quote — paste a real recommendation here. Two or three sentences on outcome and how he works is enough.
Placeholder quote — a second reference, ideally from a US remote engagement, speaking to async communication.
Open to remote engineering roles and freelance automation projects. I reply within one business day.
