👋Hi there! I'm Othniel, and I’ve been diving into AI and Data Science, working on some pretty cool AI/ML projects. My focus is all about building scalable solutions that make a real impact. Lately, I've been particularly interested in Explainable AI, ensuring that the models I create are transparent and understandable. I'm also exploring the power of Knowledge Graphs to enhance data relationships and drive smarter decision-making in AI systems.
