Crafting digital
experiences with
precision.
Hi, I'm Arsenios Hadjikyriacou — a full stack developer specializing in AI, LLMs, React and REST APIs. I build scalable, performant web applications that users love.
Technologies I work with
Building the future, one component at a time.
I'm a passionate full stack developer with experience crafting digital products that make a difference. My journey started with a curiosity for how things work on the web, and it has evolved into a deep expertise in modern frontend technologies.
I specialize in AI, LLMs, React, Next.js, and TypeScript, building everything from sleek landing pages to complex web applications. My approach combines technical excellence with a keen eye for design and user experience.
When I'm not coding, you'll find me exploring new technologies, contributing to open-source projects, or sharing knowledge with the developer community.
