About Me

I help turn complex data into clear insights that support better decisions. I build practical machine learning solutions across finance, e learning, and social impact, taking projects from raw data all the way to real world use. My focus is on creating tools that are reliable, useful, and designed to solve real problems.

I also enjoy writing and mentoring. I share what I learn through open source projects, articles, and community talks, and I like helping others grow and build confidence in what they do. Collaboration and empathy are important to me, and I am always excited to work with people who care about doing great work together.
