About me
What I use for each thing, from the machine to the browser.
I'm Antonio Leandro, a software engineer in Recife, Brazil. I work on a 15-inch MacBook Air M5 with 24 GB of memory, write Rust, Go, TypeScript, Swift and Elixir, live in the Ghostty terminal and use Claude Code every day.

Made by me
OmniGet: OmniGet downloads video and audio on Windows, macOS and Linux, free and open source. I built it with Tauri and Svelte to keep it light, and it ships an MCP server for AI agents.
Caipirinha: Caipirinha runs Windows games on the Mac with no setup. It brings in Steam for Windows, picks how DirectX becomes Metal and applies the right tweak for each game.
Setealém: Setealém is a horror game engine with a PlayStation 1 look where any NPC can have an LLM as its mind. Built to be written and tested by AI agents.
Matinta: Matinta is a small typed language with AI agents built in. Made to be written by people and by any language model, with a compiler that teaches the fix.- Pounce: Pounce is a lightweight macOS editor where each task is an agent session, with Claude Code first. It shows who is waiting for you and why, and keeps the file tree, the files and the review next to it.
Tonho: Tonho is the personal app I use on my Mac. It brings together finances through Pierre, budgeting, diet, film and book picks and a key vault, and leaves the boring part to Claude.- Grinding: Grinding is the work assistant I keep in my Mac menu bar. It records calls without a bot, transcribes them live and pulls out the requests from each conversation.
