Turning unofficial ideas
into official products
Building AI solutions that reason through complexity and produce reliable outputs that drive better decisions where it matters.
Portfolio
These are personal projects, from initial idea through research, validation and development. Built under Unofficial Brasil.

About
I turn unofficial ideas into official products. That is the foundation of Unofficial Brasil, my AI development company focused on building systems that find what matters in your data, work through the logic, and deliver outputs you can trust in production.
Every project begins with validation. Before development, I validate ideas through multi-model AI research, analytical modeling, and domain investigation, with compliance, ethics, and long-term viability checks built into the process. I only take on projects where I can see how to deliver meaningful value.
Unofficial Brasil Ecosystem
The platforms I am currently building under Unofficial Brasil:
Threefold Crown (3FC)
A Brazilian legal, tax and finance analytics platform that continuously ingests laws and regulations, currently 350,000+ with 97.7% in full text and growing, alongside 89M+ court decisions from 91 courts, all embedded for semantic vector search. The backend runs automated pipelines querying 15+ public government APIs with checkpoint resumption and daily scheduled runs, keeping the dataset up-to-date. A custom NLP layer enables cross-language legal reasoning across Portuguese legal texts.
Built with Next.js 16, FastAPI, PostgreSQL 16 with pgvector, and OpenAI API embeddings on a self-hosted VPS in São Paulo, Brazil, aligned with LGPD best practices.
Unofficial Communities
A gamified engagement SaaS platform built on behavioral science, featuring a 3D interactive world, XP & streak systems, daily missions, community health analytics, and social media API integrations. Across social media, Unofficial Brasil has reached 30M+ video views, 137K+ Instagram followers, and 49K+ Facebook followers in under 15 months. These channels serve as both the founding community and a live environment for testing new features, validating engagement models, and stress-testing product assumptions before broader release.
The community is built around Brazil's most iconic internet legend and one of the best-selling cars of all time in the country, Fiat Uno Mille. The platform is evolving into a scalable SaaS with two core layers: community management tools and branded virtual environments.
What I Build for Clients
I validate multiple AI models instead of relying on a single provider. This allows me to choose the best fit for each task based on actual output quality and to recalibrate as capabilities shift across versions.
Before founding Unofficial Brasil, I spent 11+ years over two stints at Stellantis South America, previously Fiat Chrysler Automobiles Latam, progressing from trainee to national trade marketing specialist. That experience in cross-functional enterprise operations, customer experience analysis, campaign performance tracking, inventory optimization, and margin strategy directly shapes how I define, build, and ship AI-driven solutions today.
I work in English and Portuguese, supporting clients globally.
Let's Start Building
Whether it is a specific solution or a full platform build, let's talk. I would rather understand your project first and tell you honestly if I am the right fit.
