"Dear Zacharias, Thank you very much for your time and excellent mentorship. I said to myself I wish I had such mentorship before. Beyond my expections, you offered me more ideas and useful advices, for example the tools such as excel and data visualization ( PowerIB and Tableau) which are dominantly used in industry, and the most important in data analytics that is the business aspect. You pointed out the significance of insights of data analytics for actionable decision making which helped me to focus not only on my technical skills but on customers too. Least but not least, I appreciate for encouraging me to be accountable about journey in data science, the role of team work and self mentorship. Thank you Zaracharias and I wish to speak to you in the future. Regards, Teklehaimanot "
