OLEH NOVOSAD

Waterloo,ON

Summary

I have extensive experience in software development, specifically in back-end and tools development (billing, accounting, transactions, payment systems, messaging systems). I possess a strong understanding of C/C++ languages, Ruby (language), and Rails (framework), and take pride in building well-crafted and enjoyable applications.


I held the position of a senior/principal back-end engineer, but now I want to change my career to game development because it has always been my dream. I understand that I may not fulfill all the checkboxes, and that's why I am ready to start from a junior/mid-level salary.
