About
Hello everyone! I'm thrilled to introduce myself as a seasoned Data Science professional with over 10 years of experience in mentoring learners from all walks of life. As a long-time partner with Thinkful, a leading educational company in the US, and a distinguished mentor at the Mentoring Club in Germany, I've had the privilege of guiding numerous technical learners toward success. Currently, I work as a data science consultant at GLG while also taking on new mentorship roles. With my flexible schedule and Central European time zone (GMT+1), I'm eager to connect with like-minded individuals who share my passion for data-driven innovation. My mentoring expertise lies in Data Science and Data Analytics, with a strong foundation in Python programming. Additionally, I've authored two books on Julia, as well as publications on AI-related topics (the latest one being on AI Safety). In my previous mentorship roles, I worked closely with students taking courses in Data Science, Data Analytics, or Python. Our sessions were a mix of technical and creative exercises, where we'd review their projects, assignments, code drills, and presentations. The results speak for themselves – the vast majority of my mentees completed their courses successfully and on time, while some even secured job offers within a month after our mentoring concluded. Most importantly, they've left with more than just technical skills; they've gained valuable insights into the business side of data-driven work and developed creative problem-solving strategies. If you're ready to experience the benefits of mentorship like my past mentees, I'd love to connect! Let's explore how we can work together to take your data science journey to the next level. Cheers!
