βI had the pleasure of hiring and mentoring Youssuf during his co-op term at Nokia, and I can confidently say he made a lasting impression on our team. Despite being only in his second year of university, Youssuf consistently demonstrated a level of maturity and professionalism well beyond his years. From day one, Youssuf proved to be incredibly productive β tackling complex tasks with focus, speed, and quality. He showed initiative in every aspect of his work and didnβt hesitate to dive into unfamiliar territory to deliver results. What stood out the most was his ambition. Youssuf is driven, goal-oriented, and always looking for ways to grow β both personally and professionally. Itβs rare to come across someone so early in their career who is this intentional about their development. I have no doubt that Youssuf has a bright future ahead of him, and I look forward to seeing where his career takes him.β
