My name is
Stelios Kitziris.
I’m a Senior Software Engineer with more than a decade of experience designing, building, and modernizing advanced web applications. Since 2013, I have specialized in Vue.js, Nuxt, JavaScript, TypeScript, Node.js, and Laravel.
For the past two years I’ve worked as a freelancer, helping businesses modernize their digital products, automate internal processes, and upgrade outdated systems. I’ve successfully delivered 40+ projects for clients ranging from startups to international enterprises across Europe and the US.
I combine technical expertise, product thinking, and clean software architecture to deliver solutions that are both elegant and robust. My development philosophy focuses on clarity, long-term maintainability, and performance.
Outside of work, I enjoy gaming, guitar, and cycling — passions that keep me creative and grounded.
