Mohammad — “Moh”
Senior full-stack & AI systems engineer · sole mentor at TechTips
One mentor. I run every session personally.
I still build and operate production systems. That's where my mentorship comes from. When we work together, I read your code, sit in your constraints, and remember the context from session one all the way through your roadmap.

“I’ve known Mohammad in a few different roles over the years. He first became my mentor when I was learning frontend development, and now I have the opportunity to work with him as a developer and as my manager. His guidance has been a big part of my growth as a developer. What I really appreciate about Mohammad is that he doesn’t just show you how to do something. He takes the time to explain why something should be done a certain way and encourages you to think through problems yourself. He’s patient, approachable, and always willing to share what he knows, which makes learning from him feel very natural. Today, I’m working alongside him as a developer while also learning backend development and AI engineering with his guidance. Working with him has given me the chance to learn not only from his technical knowledge, but also from the way he approaches problems, makes decisions, and works with a team. I’m really grateful that someone who started as my mentor has become my colleague and manager, and that I still get to learn from him along the way. I’d definitely recommend Mohammad to anyone looking for a knowledgeable developer, a great mentor, and someone who genuinely cares about helping others grow.”

“I’ve been working with Mohammad for over two years. He’s a very skilled web developer and an exceptional teacher. As a full stack developer, Mohammad is able to effectively analyze challenging technical problems and lead his colleagues towards implementing successful solutions. He is a kind and patient teacher with a keen understanding of when and how to push students and colleagues to encourage growth.”
“I have had the pleasure of working with Mohammad on several projects over the past seven years. He is an exceptional full-stack developer with comprehensive expertise in both front-end and back-end technologies. Mohammad has a strong command of modern tools and frameworks, which he applies effectively to deliver organized, scalable, and high-performance applications. In our most recent collaboration, he successfully developed a web application incorporating multiple engineering assessment modules, demonstrating both technical depth and attention to detail. He is consistently approachable, receptive to feedback, and committed to addressing client requirements with patience and the highest standards of quality. If you are considering developing a new application, you will be fortunate to have Mohammad on your team, he is truly outstanding.”
