Unity Developer 3+ years of production experience
16 shipped mobile titles, and game feel is the part I care about most.
My strongest skills are core gameplay mechanics, performance on low-end devices, and the editor tools designers work in.

About
I build mobile games in Unity. Three years at Vira Games (July 2022 – September 2025), 16 shipped titles, most of them running on a 1 GB Amazon Fire tablet, which is where the performance work comes from. Every title shipped to Google Play and the Amazon Appstore; the Amazon listings are the ones still live, so that is where the links go.
Vira Games runs small teams and short cycles: one developer per title, from concept to release. On every game here that meant all of it — core loop, menus, progression, shop, skins, tutorial, ads and builds. An artist supplied the art and models, and a game designer built the levels using the tools I wrote.
Small pods do not mean working alone. When a store policy change pulled every developer and tester off their own projects, I rebuilt more store builds than anyone on the team. The tech lead also picked me as his partner for an internal VR hackathon, and we had a playable build in two weeks.
Those tools are the through line. I write editor tooling so designers can build without waiting for me, and I care about how a mechanic feels, not only about whether it is technically correct.
More on how I work
Three years in one studio also means you can watch me learn in public. Rope simulation starts as a thing I could barely get to behave in 2022 and ends with me writing custom logic inside the asset in 2025. Memory starts as a build that would not launch and ends as something I design around before it becomes a problem. Cutting geometry starts as a three-second mini-game and ends as a whole game.
I also maintain a Chrome extension I use myself, and I was the person other developers came to when a reskin had to feel like the original.
Multiplayer is the direction I am moving in now. I am building a PvP physics arena on Netcode for GameObjects, and it goes up here when there is something worth playing, not before.
