Results
Every number here was measured in production. When a client is under NDA we describe the industry, we never invent the result.
Nike
Global marketing
I built AutoCrop, a GenAI service that generates image crops optimized per media format, and AutoLayout, automated marketing asset generation with correct typography, integrated with Figma, on top of a library of 16M+ digital assets.
Healthtech (US)
Healthcare · HIPAA
As tech lead of a regulated (HIPAA) telehealth vertical, I lead a production AI agent stack, agent orchestration, MCP skills and Bedrock. With metrics, caching, prompt engineering and deterministic scripts, AI cost per operation dropped 10×.
Yooga
Fintech · Restaurants
I lead the payments team of a system used by thousands of restaurants: instant payments (PIX), Apple Pay, anti-fraud, automated settlement. I introduced AI into the whole team's development workflow, more delivery without giving up architecture and tests.
B2B retail SaaS
Fintech · Food-service
Sub-acquirer onboarding, settlement and split, instant payments (PIX), Apple Pay, Google Pay and credit, embedded directly on the terminal. A real transactional operation in production, built by koy.haus, our software studio.
Topo Contábil
Own SaaS · Accounting
An accounting reconciliation SaaS I built alone, from zero to paying B2B customers in 6 months, using exactly the AI-first workflow I deploy for clients. The first contracts: Vix Logística and Podium Veículos (Fiat). Five-figure MRR from just 2 clients. Clients' accounting close went from 12 to 5 business days.
Grupo EL
GovTech · Public sector
We contribute to the EL Produções ecosystem and its subsidiaries (Sapitur, Geocamp, Georastreamento, Elonline): public management, telemetry and tracking across 9 states, through koy.haus, our software studio.
Startup (NDA)
Rescue · Product
A product a big agency had been building for 2 years without shipping. We stepped in through Haus, our MVP studio: in 30 days the backend was refactored, the UI redesigned and the product went live, ready for pitch and fundraising.
Central de Cargas
Marketplace · Logistics
A freight marketplace with WhatsApp-first driver acquisition. In the first 15 days of the project: over 3,000 truckloads posted and 4,000+ daily visits, validation speed only an AI-first workflow delivers.
