Earning Trust
I'm Eleftherios Kyriakis, a Full Stack developer from Korinthos, Greece
with a passion for creating elegant solutions and memorable digital experiences
Open to new opportunities
Full Stack Developer for
E-commerce & Infrastructure
I'm a Full Stack Developer with strong experience in e-commerce platforms, system integrations, and infrastructure environments. I specialize in PHP ecosystems (PrestaShop, WordPress, WooCommerce), API integrations, and modern JavaScript frameworks like React and TypeScript.
I've been building for the web since 2016, working with agencies, startups, and international clients, and I'm at home with production systems, deployments, and server-side environments. Whether you need an e-commerce store, a custom web app, or a reliable server setup, I'm here to deliver results.
TECH STACK
AI-Assisted Development
I use Claude Code and GitHub Copilot to ship faster, while keeping architecture, code review and production decisions in my hands.
When I'm not coding, you'll find me exploring new frameworks, contributing to open source, or sharing knowledge with the developer community. Let's build something amazing together.
Graphic Design That
Brings Ideas to Life
Beyond code, I craft visual experiences that captivate and communicate. From brand identities to web graphics, I blend creativity with strategy.
Brand Identity
Logo design, color palettes, typography, and complete brand guidelines for memorable identities.
UI/UX Design
User-centered interfaces with intuitive layouts, wireframes, and prototypes that convert.
Marketing Materials
Eye-catching social media graphics, banners, flyers, and promotional content.
Web Graphics
Custom illustrations, icons, infographics, and visual assets for web projects.
DESIGN TOOLKIT
Design Philosophy
Great design isn't just about aesthetics—it's about solving problems and creating emotional connections. I combine creativity with user research and brand strategy to deliver designs that not only look beautiful but also drive results and enhance user experiences.
Where I've
Worked
Building for the web since 2016, from freelance projects to agency teams, with a focus on e-commerce platforms, integrations, and production infrastructure.
