What you learn today is gone tomorrow. I write to make it last — turning study notes and hard-won lessons into articulated posts about software, technology, and the craft of building things.
I've been writing software since 2008 — from Java monoliths to distributed systems, from São Paulo to Vancouver. I'm a Brazilian engineer living in Canada who believes the best way to learn is to build, and the best way to retain is to write.
I came to durable-execution runtimes through the agent press, but the constraint that surprises everyone is determinism on replay. These are my notes from working a six-step payment reconciliation as a Restate workflow in TypeScript — the line that broke replay, the mental model that fixed it, and the trade-offs that come with the pattern.
An honest look at where prompts work, where they quietly fail, and the assumption we stopped questioning — that AI must make mistakes. The opening shot of a research line on moving from "best effort" to specifiable, measurable precision.
I spent a weekend pointing a coding agent at a 480k-line Go monorepo and watching it grep-loop through 38 tool calls on one question. AST-derived code graphs fix that, but the delivery shape — local stdio MCP, remote service, or skill — changes the economics more than the graph algorithm does. Here is where I would put one in 2026, with a minimal Go indexer I can drop next to the agent.
I lost an evening to a NATS JetStream pull consumer that doubled its work in production. The cause was three lines of ConsumerConfig I never wrote. These are my notes on what AckWait actually counts, why MaxDeliver = -1 is the silent footgun, and the 70-line Go contract I now ship on every JetStream consumer.
