About

I turn ideas into working products, not prototypes.

I am a full-stack developer and Computer Science student at the University of Crete, based in Paphos, Cyprus, with strong ties to Greece. My work combines engineering, design, product thinking, and entrepreneurship.

I founded EduPay, built PicMeUp and PanExams Hub, and ship client websites across Cyprus and Greece. I work with Firebase, JavaScript, Node.js, Express, SQL, PHP, WordPress, and modern frontend technologies, and I serve as a Java Teaching Assistant at my university. What drives me is simple: building things that solve real problems for real people.

Clients

Kind words from clients.

“PicMeUp transformed how we engage with customers at our café. Guests could instantly share and view event photos, the real-time upload was flawless, and Constantinos delivered a professional, reliable solution that exceeded our expectations.”

Christos IoannouOwner, Veranda Café · PicMeUp platform

“Working with Constantinos on the PSquare project was a pleasure. His technical expertise and attention to detail brought our vision to life. The website is visually stunning, highly functional, and he delivered beyond what we expected.”

Paschalis CharalambousCompany Owner · P Square Services

“Constantinos and Nikoletta created an outstanding website for StreatLab that perfectly captures our brand. A modern design approach with solid implementation made it fast, responsive, and engaging. Professional throughout, deadlines met. Highly recommended.”

Dimitris PanagiotouOwner · StreatLab

“Before EduPay I tracked payments on spreadsheets and spent every weekend working out who still owed us. Now every student’s payment status is on one screen and parents get notified automatically. It’s given me back several hours a week I used to lose to admin.”

Christos PapastylianouTutoring centre owner · EduPay platform

“Constantinos delivered our website far faster than we expected, and the result speaks for itself. He captured the character of the garden and our family’s story in both Greek and English, without us having to explain things twice.”

Stella PaloungouOwner · Avli tis Nefelis

“Most of our customers look us up on their phone before they come. The menu loads instantly and reads properly on a small screen, which is really all we needed.”
