Zlatko is a PRO! Something I was struggling with for months, took him only a few days. I think I it wasn’t for the Christmas holidays, he probably could have completed it with me during our consultation call. He knows how to operate the back end of a website, he understands coding and connection. He is just a life saver and has saved me valuable time. I’ll 100% will be working with him as I continue to build my tech business. I recommend him, but be easy on him…I still need him to be available to help me. You can’t lose when working with Zlatko! He’s excellent!

Working with Zlatko has been nothing but exceptional. From the speed of his work to his deep knowledge of code, the entire process was a pleasure, and I’m very happy with my improved website. Zlatko was responsive, knowledgeable, and willing to go back and forth with me on even the smallest details. He also sent a very detailed video addressing all of my questions and concerns, which I can refer back to for any future updates. I’m very glad I chose Zlatko and would highly recommend him for any Webflow or Framer work.

Zlatko did a very good job making a new website for my clinic. It looks very professional and streamlined, and I am looking forward to optimizing it for SEO performance. There was a little bit of delay due to some unforeseen issues on his end, but he was communicative and let me know what’s going on. I would definitely use him again in the future if needed.

Zlatko did excellent work on my Webflow site. He significantly improved PageSpeed performance, rebuilt a problematic popup natively in Webflow, and refined the mobile experience so the site is now much smoother and easier to navigate. Communication was clear and professional throughout, and he was thoughtful in addressing both technical performance and real user experience. I would happily work with him again and highly recommend his work.

Zlatko is the real deal. Not just some guy who learned Framer. A REAL web developer who builds professional components, structure, and websites. He absolutely knows what he's doing and is the most professional web builder I've worked with on this platform. I will 100% hire him again and again and again. He's my go-to guy now. Absolutely knocked it out of the park on an insane deadline with a heavily animated & polished build. Can't recommend this man enough. Super super good.

Zlatko was incredible to work with, he helped spin up our website in less than two days and responded within minutes to all of my requests. Can't thank him enough will use him again for many other projects moving forward. THANK YOU so much for your help!!! I can’t say enough about Zlatko, my second time working with him in 2 weeks and he’s completely exceeded expectations yet again. I needed tons of formatting help and mobile optimization. Every time I sent a request he responded quickly and the tasks were already done. Thank you so much Zlatko.

General FAQs

What kind of work do you specialize in?

Growth engineering across websites, SEO, analytics, conversion, AI, and automation. Across 120+ projects I have worked with founders, marketing teams, SaaS companies, healthcare and wellness businesses, agencies, and professional service companies.

Are you primarily a designer or a developer?

Neither label fully describes the work. Development is the technical foundation, but projects often include strategy, UX, SEO, analytics, CRO, automation, and growth. I can identify the problem and implement the fix.

What services do you offer?

Four core areas: web growth and digital experience, SEO and organic growth, conversion and analytics, and AI and automation. I also take ongoing fractional Growth Engineering engagements.

Can you lead a project from strategy through launch?

Yes. Discovery, analysis, strategy, design and build, tracking, launch, and optimization. I stay on the problem instead of handing each piece to a different specialist.

How long does a typical project take?

Most focused websites take two to six weeks from kickoff to launch. Smaller landing pages may take one to two weeks. Larger platforms, migrations, or ongoing leadership work run longer because strategy, design, and implementation stay connected.

Do you take website redesign and development projects?

Yes. Website redesign and development sit inside web growth work. The site still needs a commercial job, SEO protection, and a way to measure what happens after launch.

Do you work with internal teams?

Yes. I work with founders, marketers, designers, engineers, agencies, and content teams. Sometimes I lead the work. Sometimes I plug into an existing team.

What makes your background useful in a leadership context?

The useful part is cross-disciplinary execution. I can read the data, decide what to change, and implement it across the website, search, conversion, and automation stack.

Do you take ongoing or fractional engagements?

Yes. Ongoing Growth Engineering for companies that need someone to keep identifying and implementing improvements across the website, SEO, analytics, conversion, and automation.

Are you open to full-time leadership opportunities?

Yes. Alongside selected consulting work, I am open to full-time roles in Growth Engineering, digital growth, marketing engineering, AI implementation, web growth, and digital experience.
