Why Our CTO Banned TypeScript After One Migration
I migrated one of our biggest JavaScript codebases to TypeScript — and after everything started working too well, our CTO banned it.

I'm a senior software developer from Brazil focused on open source and developer tools: build and deploy pipelines, type-safe APIs, code generators and, lately, agent harnesses. Most of my work is TypeScript, with Rust where it pays off.

A guide to work with Cache over State for remote data management
I started coding in late 2018 with Java, writing Minecraft plugins. Open source came soon after and never left: axios-cache-interceptor, prisma-json-types-generator and the Kita ecosystem all grew out of problems I hit at work, and today the packages I publish see around 10M npm downloads a month. My first job came in 2021, building web apps and deployment automation for a software house, then two years on the backend of a feed management system for cattle farms. From 2024 to 2026 I was at Zephyr Cloud, working on bundler plugins, a multi-cloud edge runtime, billing and the infrastructure of an AI chat platform.
