About Jonathan

I design, test, and automate — with a developer's approach that goes beyond simple recipes.

Currently on assignment at a recognized company in the utilities sector, I have developed SQL expertise within the team, particularly in complex volume queries on critical energy sector databases. Beyond QA, I am involved in functional analysis, documentation, and collective skill development.

On the development side, my fullstack background covers React, Node.js, and AI integration — applied to concrete projects: a visual SQL builder for creating queries without writing code, and a gamified nutrition app in React Native currently under development.

My portfolio reflects what I actually do: technical, polished interfaces designed for real use. Not templates.

Full remote · Clear communication · Structured delivery.

What I bring to your mission: a transversal dev/QA/AI vision, the ability to ramp up quickly, and a genuine attention to detail.
