About

Gameplay developer, trained at Rubika.

I'm a Unity developer specialised in gameplay programming, systems and networking. I studied at Rubika (Supinfogame) in the Programming Bachelor, and I now work as a freelancer under the STUDIO N29 banner.

I like mechanics that feel good in the hands: readable combat, a spell that responds at the right moment, networking you never notice. My experience also gave me full-stack web, LLM / AI and prompt-engineering skills.

I fit into a team quickly, communicate clearly and like shipping code that others can pick up.

Reviews

What clients say.

Strong all-round contribution across. Djason delivered the first draft of the match simulation algorithms, integrated RP Vision from the GDD with solid stabilisation and performance gains, and set up a clean Unity architecture, Git workflow and documentation. Djason was a reliable partner in production meetings, helping scope and split tasks clearly. Highly recommended for Unity game development.
