I cannot recommend him enough for your project!Olexander Petrykov πŸ‡±πŸ‡Ί

Sergii was an amazing thought partner to me, in addition to building the alpha of my parenting app in Bubble. I came to him without a design or wireframes and he helped me think through a design system (even though that was not in the original job description) and consistently showed up for me multiple times a week for many months as I pivoted and changed my mind. He was so patient with me. Extremely honest person who does great work. I can't recommend Sergii highly enough!Molly Siems Cavanaugh πŸ‡ΊπŸ‡Έ

Sergii is simply amazing to work with! Am in my third project with Sergii now and all of them has worked very well. Besides being a great No-Code developer Sergii really understands business objectives and can therefore come up with great improvements as well as working with not 100% finalised specs. I can highly recommend working with Sergii.Peter Schierenbeck πŸ‡ΈπŸ‡ͺ

Sergii Shpak - Bubble NoCode Developer

As a seasoned freelance Bubble developer, I have been providing top-notch no-code solutions to clients on Upwork since 2020. My dedication to excellence has allowed me to establish a strong reputation as a reliable and skilled developer on the platform.

I realized that traditional software development can be slow and costly while working on a startup that aimed to create a blockchain solution for the real estate industry in Germany. In search of a more efficient solution, I discovered and started learning about Bubble.io.
