Full stack developer and product builder in Florianópolis — turning raw problems into shipped software with React, Node.js, and applied AI.

Engineering close to the business.
Multi-tenant PostgreSQL with row-level security, multi-agent AI orchestration, and dashboards built from the operational reality they serve.
Full stack developer with
a product owner's instincts.
I have two years of experience building digital products from zero — problem discovery, architecture, integrations, and delivery to real clients. I pair technical execution in React, TypeScript, Node.js, C#/.NET and PostgreSQL with product and business thinking. As a founder I took Loogi AI to the finals among roughly 40 projects in an accelerator program, reaching a $2M BRL valuation and securing $100K BRL in funding, and I was recognized nationally by CNPq at the 31st Prêmio Jovem Cientista.

- Designed and queried PostgreSQL data models for data-driven systems, focused on performance and user experience.
- Translated business needs into dashboards, administrative workflows, and operational tools using Git/GitHub and agile methods.
Founder & Full Stack Developer — Loogi AI
- Conceived and built an AI-powered SaaS platform for paid ad automation across Google Ads and Meta Ads, with a multi-agent architecture of 6 specialized agents orchestrated via the Claude API.
- Designed a risk-zone permission system, a credit-based model (“Loogi Credits”), and the full product onboarding flow, from frontend to campaign-data integrations.
- Reached the finals among roughly 40 projects at the Link School of Business Demo Day, achieving a $2M BRL valuation and securing $100K BRL in funding.
Founder & Full Stack Developer — NeuroPDM / TerapiaABA
- Built a multi-tenant platform with TanStack Start, TypeScript, and Supabase/PostgreSQL using row-level security for ABA therapy clinic management.
- Delivered features for a real paying client: AI-assisted intake via OCR, clinical assessment templates (VB-MAPP, ABLLS-R), PDF/DOCX report generation, and a guardian portal.
- Structured and rolled out a formal clinical taxonomy (v1.0), approved by the client, replacing a previous heuristic classification system.
Sales Administrative Assistant — Casas da Água
- Provided operational support in a retail environment — orders, inventory, and billing.
- Built hands-on knowledge of cash flow, margins, and customer behavior that now informs my product decisions.
