ABOUT ME
React/TypeScript/Next engineer with 10+ years experience
React/TypeScript/Next engineer with 10+ years experience

I’m a full-stack developer and professional mentor with over 10 years of experience, including extensive work with React, TypeScript, Next.js, databases, and cloud services. I work with small businesses, absolute beginners, experienced developers, and career changers.

I offer tutoring, code review, long-term mentoring, and career coaching. I love helping people discover what they can build and where those skills can take them.

If you’re looking for a job, we can practice coding and system design interviews, strengthen your portfolio, and work on explaining your experience confidently.

I specialize in helping developers build with AI agents, including Claude, ChatGPT, Cursor, and GitHub Copilot. I can help you turn an idea into a clear plan, guide your agents, and improve what they generate. If you’re looking for a vibe coding coach, I can help you build efficiently and enjoy the process.

I really enjoyed my session with David. He was pleasant to work with, gave me some valuable feedback, and left me with a clear direction to head towards and improve.

We discussed a bunch of product ideas I've been accumulating lately; then we figured out which one we'll start on and how. We settled on doing it properly: gather requirements, define the system design, and only then start the actual implementation.

In the first half, we reviewed my homework, whereas in the second half, we focused on discussing my ideas for apps and games. The discussion was prolific, letting me expand my notes so I can analyze them more deeply and figure out which project we'll work on next!

We dug through a lot of my code that I wrote before the session, and David helped me figure out the most cryptic parts. Now the most troublesome portions of my solution are clear to me!

I've learned a ton about routing today, and we even briefly discussed the future steps to make sure the data is centralized between front-end clients

In the first half, we went through the home assignment; in the second half, we did a sort of "whiteboard" activity where I was updating the app in real-time

A round of review with a lot of practice on my end today. I've drilled the state lifting, and I've been taught the main patterns of changing the state. The home assignment is a tough one this time, let's see how I handle it!

We went through my home assignment and that was the biggest portion of today's session. That way, I managed to get a better understanding of the task itself and the nuances of implementation.
