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.
DBOS reuses Postgres as the durability layer for workflows, while Temporal runs a dedicated cluster. The right choice depends on team size, workload shape, and where you want your operational budget to go. This is a practical rubric for picking between them.
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.
