    def __init__(self):
        self.location = "Lagos, Nigeria"
        self.current_focus = ["Backend Development", "System Design", "DevOps"]
        self.learning = ["Kubernetes", "Microservices", "Cloud Infrastructure"]
        self.interests = ["AI/ML", "Problem Solving", "Open Source"]
    
    def say_hi(self):
        print("Let's build something amazing together!")

What drives me: I believe technology should solve real problems. Every line of code I write is a step toward creating solutions that make a difference.
