Game developer in Unity and C# for more than 4 years, 2 of which were on commercial projects. Even before I officially started to work on commercial projects in a company, my main goal was to acquire skills and knowledge as close as possible to the senior level, with the main emphasis on the ability to write code and architecture (created both component-oriented on scriptable objects and statemachine-oriented practically without monobehaviour architectures and all variations between them) with all principles (OOP, SOLID, DRY, KISS, YAGNI) and patterns and mastered them, and optimization skills (rendering, physics, and code). I have a table with more than 60+ points on all the tricks and optimization methods that can be applied, sorted by performance gain on the part of the CPU/GPU and time cost/complexity to implement. I am confident in all internal Unity tools (animation, particles, physics, profiler, navmesh, etc.) and have done all types of projects, UI, 2D, 3D, URP, HDRP, mobile, WebGL, client-server, and multiplayer. And from time to time I continue to challenge myself with implementing complex mechanics in my free time. I have experience working with Firebase and integrating advertising and payments. I have strong knowledge of asynchronous programming (UniTaks) and the use of Addressables and Bundles and I love using them. I have experience creating custom tools for the Unity Editor (example - http://github.com/Volandimer1/Test1). During my official employment, I had experience in creating projects from scratch to release, participating in all processes of the project life cycle. Before this, I made applications in Android Studio with admob integration. I have a higher education in the specialty "software engineer" at the faculty of "applied mathematics" of the Dnepropetrovsk National University named after Oles Gonchar. I was an Olympiad participant at the regional level in mathematics and programming. Responsible, loves to learn, and loves to program. I have excellent communication and mentoring skills.
