UX/UI design for marketplace automation software

Here’s a refined look at my UX/UI work for Deltologic — a software agency specializing in automated tools and integrations for marketplaces like Amazon, eBay, and Allegro

Deltologic wanted a fresh, modern website to support their expansion into the US and EU markets. The focus was on converting visitors into leads, showcasing their expertise through a rich portfolio, and building trust via a blog and visible brand visuals.

To humanize a technically complex service, we integrated real photos from their office and team, plus an original gradient on the sub pages. Not just decorative—these elements support credibility and engagement.

The homepage includes a clear CTA ("Work with us") placed strategically across pages. We built filtered blog categories and portfolio pages to improve SEO and lead generation. Rich data highlights (like benefits and KPIs) are used to reinforce credibility .

Each case study subpage follows a consistent, scroll-friendly layout — starting with project goals and client context, followed by scope of work, selected screens, testimonials, and final outcomes. This structure makes it easy for prospects to assess Deltologic’s capabilities without friction.

We didn’t just “place a button at the bottom.” The “Work with us” section was designed as a true decision point — built to stop the scroll, deliver clarity, and create trust.

Instead of a vague “Submit,” it says “Fill out the contact form” — a small copy change that adds purpose. Right below, a row of recognizable client logos serves as social proof, turning a cold CTA into a warm invitation. And that headline? “Let’s build something amazing” — emotion meets action.

It’s not decoration. It’s persuasion by design.

I was responsible for the full UX and UI design — from information architecture and wireframes to the final design system, all handed off in Webflow-ready Figma files.
