Client feedback
Ivan is an extremely talented and experienced coder I’ve had the great fortune to work with. He has helped me extensively with a SaaS product built with the Laravel PHP library, React, MySQL, AWS, and a bit of Node JS. He brings a thoughtful approach to each project and is an excellent communicator who not only works well with peers but can lead teams. If you’re looking for a VERY solid and well rounded engineer, then you’ve found the right guy. I highly recommend Ivan.
Very good work from Ivan who took over the backend of a complex SAAS with many features and brought some much needed professionalism into our processes. I definitely recommend working with him!

About Ivan
Close to the code.
Invested in the product.
I’m an engineer who enjoys understanding the whole system — and staying hands-on with the details.
My work spans long-running SaaS products, new platforms, and License Bridge, a product I conceived and built. I work directly with founders and product owners to turn business requirements into technical decisions and working software.
Alongside implementation, I review code, mentor developers, and help small teams make deliberate choices about what to build next.
