For Codementor mentees: I remember exactly what it feels like to be stuck. You are writing good code, but you aren't sure how to break through to the next level. Whether that is becoming a Senior, Staff, or Principal Engineer, or eventually a VP of Engineering or CTO.
Nobody hands you a manual for that transition.
I started exactly where you are. I went from building React UIs as part of a scrum team to leading large organizations engineering the systems for multi-billion dollar satellite assets.
Today, as the CTO of Symphonee AI, I still code every day. I do this because you can't lead engineers if you don't understand the reality of the work.
I am here to help you see the things you don't know you don't know.
I want to be the mentor I wish I had. Someone to cut through the noise, show you the shortcuts I learned the hard way, and help you get to that next level faster.
Whether you are feeling lost, facing a specific technical challenge, or just ready to move up, let's talk.
