About
Profile
Engineering focused on backend and architecture, across SaaS products and mobile applications. The day to day is Node/NestJS, React/Next and what holds it up underneath: data modeling, performance and security.
The practice is to understand the mechanism before picking the solution — which tends to save rework when a decision is hard to reverse.
The blog collects notes from the way: what worked, what broke, and why.
