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

I offer tutoring services including, bootcamp support, long-term mentoring, and a complete educational experience. I provide full support to development job-seekers, from mock interviews to career coaching. I can help you fix bugs quickly and fully understand each part of the solution.

I am a fullstack React and TypeScript engineer with over 10 years experience. I have extensive background with tools like NextJS, ExpressJS, PostgreSQL, MongoDB, Google Firebase, and Convex. My specialties are absolute beginners, small businesses, and aspiring engineers.

Everyone that wants to make great software should be able to. I can help you learn to make apps with the features you want and explain exactly how they work. I also started without a formal background in computer science. I know you can cross that gap in an engaging, accessible, and fun way.

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.

We got through comments in my PR, I addressed them, and requested the review. After approval, David taught me how to work with forms in React. The new home assignment included not only a practical part, but also a theoretical one about lifting the state. This way, we'll spend a bit less time during out next session as I'll be slightly prepared. A great approach!

a true dive into TypeScript + React, many things make sense now to me, thanks!

"Excitement" is an incorrect word to describe how overwhelmingly happy I was to finally unravel the advanced concepts of TS. I had an absolute blast of a session, now I'm looking to more discoveries together 🔥

David was really awesome! He allowed me to tell him what I needed each session - whether mock interview, lecture or practice problems. Highly recommend!
