About this session
Over the years, I’ve assessed countless candidates on problem-solving, coding, and system design skills, as well as behavioral and communication abilities. This session is designed to simulate a real interview environment, giving you practical, targeted feedback so you can identify strengths, address gaps, and improve your confidence. I typically run these sessions on weekday and can also accommodate some weekend slots upon request.
Your mentor
Hello! I’m an Electrical Engineer with over 10 years of experience in data analytics and AI. I hold both a Master’s and a Ph.D. in Engineering, which have shaped my deep technical foundation.
Currently, I work at Microsoft, specializing in Generative AI, Large Language Models (LLMs), and copilots within the M365 ecosystem, following a tenure at Microsoft Research. My work blends research and engineering, from evaluating AI models to building impactful, real-world solutions, work that has led to multiple patents and publications.
Over the past 6 years, I’ve mentored 300+ students through MentorCruise, Udacity, and Data Science Dojo, helping them go from fundamentals in Data Science and Machine Learning to confidently applying those skills in projects, research, and industry roles. I’ve also consulted for companies like Shell, Fastshop, Symrise, and Petrobras on advanced AI and ML initiatives, giving me a strong perspective on what works in practice.
If you’re looking to strengthen your skills in DS, ML, or Generative AI, whether you’re a student, career-switcher, or working professional, I can help you create a personalized learning plan, master technical concepts, and build portfolio projects that stand out. Let’s connect on LinkedIn or send me a message here so we can start mapping your next step.
Looking forward to chatting!
