01 / About
Curious before clever.
I ask the right questions before jumping to solutions.
Starting out as a functional analyst shaped how I develop today: understand the real problem, make deliberate choices, and keep the people using and maintaining the product in view.
I work across Java backends and React or Angular frontends throughout the full development lifecycle. I thrive in agile teams where knowledge is shared openly and complex topics become conversations everyone can follow.
