Development Details

Pixel Perfect Accuracy

I make sure your static design files (Figma, AdobeXD, Sketch, etc.) are accurately brought to life using the power of Webflow.

Responsively constructed

User experience is always at the forefront of my work, so you can rest assured that your new website will look great and be easy to use and navigate on any device.

Systematic approach

I build your site with best practices and intuitive class naming, using systematic approach very similar to BEM technology so you can understand, edit, and grow your site with speed.

Custom Code & API Integration

I can integrate most of third-party tools. Very often there is lack of capacity of standart functions of Webflow because of custom tasks from my clients. In such cases I can write additional custom code. I'm quite proficient with HTML/CSS/Javascript/jQuery

I have extremely high standards for the my work using an extensive launch websites I produce and I triple-check all of checklist.

Webflow Interactions

I can add animation effects like link and button hover states and more complicated interactions.

What They Say

"TL:DR - Your search for the best Webflow Developer ends here. Period.

Where do I begin with Stepan? To leave a worthy enough review of this outstanding Webflow developer would probably exceed the 5000 character limit allowed for this review. I’ll begin by saying that I’ve worked with Stepan on numerous projects over a couple of years now, and have logged 200+ hours with him to date. 

As a designer and project manager, the need for a developer who has an eye for detail and pixel perfection is a must for me. Someone with high levels of expertise, and with low levels of pride and ego—a mix that is harder and harder to come by these days. Interviewing potential employees and contractors is always a difficult task. Most will oversell themselves, and almost always underdeliver. Stepans is the rare case—he was the needle in a haystack—an exception to the norm.

Stepan always delivered perfectly rendered assets, with expert-level knowledge and implementation. Whenever I came across what I thought might be a problem or roadblock, he would always say “not a problem”. He was always ready with a solution. In the very rare case, he didn’t have one on hand, he was honest, upfront, and always assured me he would do what it took to get it the way I wanted. He would never give me lines like “that’s too hard”, or “let’s not do it that way”… his responses and suggestions were always to get the job done right and based on the project briefing. With Stepan I always felt like we were on the same team, working toward the same goal. He was always striving to deliver the solution I was envisioning and not the one he might be limited to—limits I was never able to find. His work was always quick and thorough. He delivered work almost always on time and/or before deadlines. In rare cases he needed more time, he was always available to communicate. When presented with updates or changes, there was never hesitation or pushback—simply a ready-to-go attitude.

I consider it a pleasure to have worked with Stepan and truly hope to continue working with him again in the future. If you need someone to build out your project in a timely manner, with expert-level knowledge and pixel-perfect ability, Stepan Kostenko is 100% that someone."

I've worked with Stepan for over 3 years on our Webflow website project, and he's consistently delivered exceptional work. Stepan is reliable, quick to respond, happy to dive into new tasks, and delivers great work on tight timelines. He is an eager learner has also been instrumental in helping us understand how to solve problems, creating learning materials and video walk-throughs, so that we can do so for the future. Stepan has been a wonderful support for our team across a range of different projects over the years, and I would recommend him for support with any of your Webflow-related projects.

Sad that I can’t give 10 stars to Stepan, because he would deserve them. There's really nothing to complain about, the whole cooperation was fantastic, and the final result exceeded my expectations. In the beginning we had few requirements for the website, but as time went by the features that needed to be implemented increased. Especially a lot of custom code had to be programmed. Stepan also had built an API for transitions of data. His skills are incredible, and I have the feeling that he can do everything. He had a solution for every problem. Stefan is also very honest and that is what I appreciated most. I can trust him blindly even though he is sitting several thousand kilometers away from me. I will definitely continue to work with Stepan. Stepan thinks proactively and provided solutions that took my online business to the next level. Thanks for all your hard work Stepan!

Lukas Szwedowicz

Stepan is a real Webflow expert. Not only did he bring our vision to life, but he helped shape the technical approach throughout as we got to grips with the platform. We provided designs in Figma & he created them as a responsive Webflow site with pixel perfect precision. His English is strong & I didn't have any issues with communication. I would highly recommend Stepan & I hope we have the opportunity to work together again on future projects.

Stepan did an excellent job creating our website on webflow. I wanna highlight that he paid attention to details and completed the job not only up to our expectations but also before the given deadline. The communication was smooth. I can definitely recommend Stepan and would hire him again myself in the future.

Thanks again, Stepan.
