"We hired Herman as a technical support agent to support our clients in FinTech and security. He did an amazing job and displayed a deep understanding of the technical concepts required for the role. The customers he supported were really happy with the service and solutions provided. His progression into software engineering was just a natural step and I am pretty sure he will do a great job for any business that works with him. Highly recommended. "

"I hired Herman Kravchenko to develop the mvp of our internal business app. Working together with a couple others to complete the product, he stood out as the subject matter expert on all technical aspects of the project. Without his technical competence the project would've been impossible. I've reached out to him for smaller work in the past, and have another project coming up where I plan on using his professional services. I definitely recommend his work to anyone needing software development and associated services. Thank you Herman! "
