At KAIA Systems, my own company, I built PRONTO, an operations system for food and retail businesses that's in production with customers. It covers orders, point of sale, inventory, WhatsApp, Brazilian tax invoices, and billing.
I also built KAIA Sync, a local-first TypeScript sync library with code generation and durable jobs and workflows on PostgreSQL, published as npm packages. KAIA WhatsApp extends it with WhatsApp sessions and idempotent delivery of messages and media.
I built a WhatsApp ordering assistant using LLMs and validated it with an automated evaluation suite. Before KAIA Systems, I built a custom commands and utilities mod for Minecraft servers at BisectHosting.
At GRVA, the Virtual and Augmented Reality Group at Federal University of Uberlândia, I developed educational serious games in Unity as part of an undergraduate research project. I also developed Java Minecraft mods for live events at Quackity Studios, and created Industrial Revolution, a Minecraft mod with industrial machines and graph-modeled energy and item networks.
