Architecture discovery work
Mersad did a great job on our architecture discovery work. He took the time to understand the requirements, delivered a clear and well-structured assessment, and his recommendations were practical and easy to follow. Communication was responsive and professional throughout. A pleasure to work with, and I'd gladly engage him again.
