I’ve mentored dozens of engineers and led teams through high-stakes work in reliability, scalability, and fault tolerance at companies like Google and Syllable. To me, mentorship is about more than just answering questions; it’s about building confidence, guiding through ambiguity, and sharing hard-earned lessons in a practical, supportive way. I enjoy meeting people where they are, helping them overcome challenges, and supporting their growth in a way that’s tailored to their goals.
