David Triantafyllou

Hi there! Welcome to my personal portfolio page.

I'm David Triantafyllou — a passionate game developer and experienced software engineer based in London.

With a background in Computer Games (MSc, University of Essex) and over six years of professional software engineering experience across the UK and Greece, I've built a career that bridges the creative world of game development and the structured world of backend systems.

My journey started in software engineering, where I worked with leading technologies like C#, .NET, Java, and databases such as Oracle and PostgreSQL. As a .NET developer, I've designed APIs, developed web applications, and collaborated in Agile teams, while mentoring junior developers along the way.

Parallel to my software career, my true passion has always been creating games. I specialize in developing physics-based and mobile games using Unity 3D and Android Studio. From my early experiments to publishing games on the Google Play Store, game development has been more than a hobby — it's a way of combining creativity with technical precision.

Whether working on a complex software solution or bringing a game idea to life, I bring the same level of dedication and attention to detail. If you'd like to collaborate, feel free to explore my portfolio or connect with me.
