Hi, I’m Georgios.
I’m a Principal Engineer with 13 years of experience building and scaling systems at companies like Meta, Amazon, Google, Microsoft, and Samsung. My work has spanned machine learning, system design, and platform engineering—often leading high-impact teams that delivered production-ready solutions at global scale.
I’ve conducted 400+ interviews across top tech firms and have coached dozens of candidates into senior and principal roles. I focus on system design, ML system design, algorithms and data structures, coding, and behavioral interview prep.
I find energy in helping engineers unlock their next level—whether that’s nailing a staff-level system design interview, tightening behavioral stories to land a dream role, or just debugging a tricky algorithm together.
If you’re looking for a mock interview, career advice, or strategic guidance to move from senior to principal, I’d be excited to help. Let’s work together to sharpen your edge and take the next step with confidence.
