Full-stack developer & app creator
Hi, I'm Petros Manelidis
I design and build full-stack web and mobile products — from custom booking platforms to apps used by thousands of students.
Portfolio · 2026 · Chania, Crete · Available worldwide
01 — End to end
From first pixel to production.
I take products from idea to launch on my own — architecture, interface, data layer and release.
02 — Shipped
Software that ships.
A production car-rental platform with payments and an admin dashboard, and a campus app used by around 10,000 students.
03 — The craft
Built to last.
Software that stays maintainable and feels good to use — clear hierarchy, real content, motion with purpose.
About
A developer who ships.
I'm Petros Manelidis, a full-stack developer from Chania, Crete. I build complete products end to end — design, frontend, backend and deployment.
I founded and built Calma Car Rental, a production booking platform with payments, automated emails and an admin dashboard, and I created myHMU, a hybrid web and Android app used by around 10,000 university students. I care about software that ships, stays maintainable and feels good to use.
