Freelance OpenAI Developer - Kevin Gonzalez
Freelance OpenAI Developer5.0 (2 reviews)

American (native English speaker) born and raised in New York City and now living in the richest country in the world, Luxembourg! I'm a product-centric CTO, engineering leader, and software engineer with 12+ years of experience crafting world-class software. I have strong expertise in React, Node, TypeScript, Python, Go, AI/ML, Azure, and much more. I've scaled organizations responsible for defining, engineering, and operating mission-critical systems optimizing $10B+ space assets while partnering with companies like SpaceX and other space. I have a powerful track record of establishing autonomous product-minded teams, pioneering agentic development workflows, and driving measurable commercial impact. 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.
