"Wow. This guy is the true definition of a professional developer. His ability to code is obviously elite, but what I really appreciate is that he's super easy to work with. He's been calm and patient while we navigate through changes in our scope of work and some other issues. When you find someone like K who's smart, but also cooperative, you have a great chance at a successful project. ✅ So far, he's been able to work through a set of complex requirements and convert them into scalable, working solutions. He already feels like a member of our team instead of someone we've just hired to perform a task. Thank you so much for your help so far, let's keep going!"

"Konstantin was absolutely amazing. Would definitely hire him again."

"K is a great engineer, very enthusiastic and creative. K is always thinking of new techniques or tools to apply to improve our engineering processes or improve / simplify our product."

"Absolutely incredible full-stack dev. We interviewed what felt like every python/django expert on upwork and Konstantin was very clearly immediately superior. What i especially appreciated about Konstantin was his incredible communication. He was great at managing expectations as well as elevating issues he saw with UX/tech-stack/development. You can tell his experience as a CTO taught him all the non-task related things that are just as important to have finished when you're trying to scale a project and a startup. It's a luxury to have developers that are as self-sufficient and good at self-managing as Konstantin. Highest of recommendations."
