Maxim Zubarev

As a Forward Deployed Engineer at CopilotKit, Maxim was our link between Fortune 500 customers and the product. He worked side by side with their teams and turned what he heard into features that are part of CopilotKit today. Hand him a problem, and the next thing you hear is that it’s fixed, shipped and documented.

His range went well beyond that. He helped build our newer products, bringing AI agents into the apps and tools teams already work in, and he pushed our own team to work AI-natively by building tooling that made everyone faster. Engineers who think this carefully about the customer are rare, and he is one of them.

Maxim is a fantastic engineer. Among his many notable accomplishments, he brought CopilotKit to React Native, built it from zero, and it's now past 350,000 total downloads. A whole new community of mobile developers can now build with CopilotKit because of him. He often did the unglamorous work that makes a product enterprise-ready: self-hosted and cloud-marketplace deployments that just work, and agent conversations that stay fast and reliable even when they get huge. Maxim owns problems end-to-end and ships work that lasts. I'd hire him again in a heartbeat!

Maxim is a rare asset. He was our first front-end developer, and was the lead on all our front-end strategy long after additional developers joined the team. Maxim is not just very technically-deep and super knowledgeable, he is also the rare kind of professional who proactively and continuously identify issues, often before they happen, and tend to them. He is super quick and very strong technically, but always open to assist his colleagues and anyone who needs it. In terms of commitment, like many startups we often needs way extra time investment, and Maxim was always the first to step up, and the one to do the most in both investment and outcome. If you need to build some big and fast - that's the person you need.

Maxims technical decisions enabled us to move rapidly and build our product in the shortest amount of time for multiple platforms. You can feel his attention to detail in code and user experience in the apps he builds, and his desire to improve and integrate with processes and colleagues makes Maxim an invaluable asset to any team.

Max is a world class mobile app developer who exceeds expectations. I would highly recommend Max!

As we approach launch of our mobile app, I couldn't be more grateful to have Maxim leading the charge on complex social / interactive features & always bringing his top-notch React Native skills & dedication to help making this app shine! 🙏

Maxim has been great to work with over the past year. His thoughtful insights and technical contributions have been invaluable to us. Having found him through a programming contest (that he won), we were not surprised, and he exceeded our expectations.

Maxim is supporting me on my React Native journey for several months already. Anytime I need help, he is there for me and responds with a solution. He is highly skilled, so he already knows a lot. And the best part: he actually enjoys helping you!

I've been working with Maxim for a while now, and I can confidently recommend him. He's an exceptional professional. Clear communication and well-organized approach.

He stands out for his remarkable proactivity and self-management skills. Once the goals and rationale behind a feature or task are clear, he consistently delivers exactly as promised.

What I particularly value about Maxim is his ability to anticipate potential issues and proactively contribute to strategic discussions, always considering how technical decisions impact various aspects of our business.

It has truly been a pleasure working with him, and I look forward to our future collaborations.

Maxim delivered the whole package. The new website and marketing automation captured a lead that ended up paying €60,000 for a commercial fencing project. The entire system paid for itself tenfold in the first month.
