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!

We discussed a wide range of topics, including computer vision, quantization, multimodal models, agentic AI, MLOps, and open-source software development. I initially reached out to Sara because I was looking to build a portfolio to help me transition into an AI/ML career and was still brainstorming project ideas. She was quickly able to provide feedback and share resources that helped me refine those ideas into concrete projects I could build. During our calls, I would walk through my projects, and she would share actionable guidance on how to present my work more effectively and what additions could help it stand out. Her feedback went beyond the code itself, including best practices for collaborating on open-source projects. In addition to the excellent technical insight Sara brings, she is very patient and attentive. She consistently helped me calibrate where to focus and how deeply to invest in topics so I could make efficient progress toward my goals. I would strongly recommend Sara to anyone looking for practical technical mentorship and career guidance, especially those building a portfolio for AI/ML roles.”
