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 maintain a personal tech radar to organize what I'm exploring, and this site is where those explorations become something more permanent. Every post starts as rough study notes and evolves into something I'd want to read myself.
Cell-based architecture contains blast radius, but it is not free. A look at what Slack, DoorDash, and Roblox actually paid for cells in production — and a checklist for the cheaper fault-isolation patterns most teams should reach for first.
JetBrains Tracy is a Kotlin library that wires LLM-aware tracing into your app on top of OpenTelemetry. This post walks through how I integrated it in a Spring Boot service, the design decisions that matter, and the failure modes teams hit once LLM calls become the hottest path in their system.
Fully autonomous agents are hard to bound, hard to test, and expensive to operate. A deterministic backbone with narrow agent steps gives you the control flow back while keeping the intelligence where it matters. Here is how to design, test, and migrate toward it.
Most AI memory benchmarks grade on recall and stop there. That hides the real failure mode: stale facts quietly poisoning the context window. Here is a lifecycle-based evaluation framework that tests recall, revision, and controlled forgetting across the change points every long-lived project goes through.
