Senior software engineer from Brazil
Building tons of stuff
This is a small home for my work, notes, and essays about software: the parts that run in production, the tools that shape how teams think, and the product judgment between them.
Featured projects
Small, durable systems over portfolio theater.
Fabric
activeA Git-backed protocol for scoped repository direction, lifecycle records, projections, receipts, and causal provenance across agent work.
Luc
activeA terminal AI agent with a streaming TUI, local tool execution, OpenAI-compatible providers, and runtime extensions.
Weaver
activeA local-first Go CLI for stacked Git branches, dependency DAGs, stack sync, and ephemeral integration branches.
Latest writing
Notes on systems, tools, and engineering taste.
Direction Is Not Memory
Why repeated agent corrections in real repositories need scoped repository direction, not more transcript memory.
What An Agent Harness Actually Owns
A look at the runtime boundaries around agentic tools: the turn loop, provider adapters, tool execution, extensions, and local trust.
The Branch Nobody Could Explain
How large-repo branch chaos turned into a local-first way to declare dependencies and build integration branches.
