"Ruslan is a very competent solutions architect and developer. I initially consulted him regarding standing up an enterprise, client facing solution. He clearly demonstrated a strong command of the latest software engineering principles and was able to articulate clearly. He was able to quickly identify the needs of the project and layout the most efficient solutions for the work. I look forward to working with him in the future."
