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.

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.

Hi, I'm Zlatko.

I've been building for the web for 7 years. 120+ projects across Fiverr, Upwork, and direct clients. For most of that time I built in Webflow. Then AI changed how fast you can build, so I changed what I build. Right now I'm focused on websites, tools, and the systems that make them worth having after launch.

What I build.

Websites, tools, and the systems that make them work. Grouped by what you actually need, not by which tool I use to build it.

Websites that work after launch

Custom-built Next.js and Framer sites. Fast, owned by you, no platform lock-in. Built so your team can edit and operate them without calling a developer every time something needs to change.

Next.js marketing websites
Framer landing pages and sites
Webflow to Next.js migrations
Headless CMS setup (Sanity, Payload, Storyblok)
Vercel deployment and infrastructure
Visual editing layer for client handoff

Products and tools built around websites

The layer between the website and the business. Dashboards, portals, calculators, lead flows, and custom business logic. The stuff that makes a website useful instead of just visible.

Client dashboards and portals
Lead capture and routing
Quote calculators and interactive tools
Automation workflows (n8n, Make)
CRM integrations
Custom business logic

Content systems and structured data

CMS setup your team can actually use. Blog, resources, case studies, events. Structured so editors can publish without breaking things and content gets found by both search engines and AI tools.

Sanity, Payload, Storyblok, Strapi setup
Content modeling and architecture
Technical SEO implementation
Schema and structured data
AI search visibility (AEO, GEO)
llms.txt setup

Animated code components
Landing page templates
Code overrides
Framer plugins
Free and paid tiers
Custom component development

Performance and technical foundations

Slow sites cost you rankings and conversions. I fix the technical layer: page speed, Core Web Vitals, image optimization, code cleanup. Before/after report included.

Core Web Vitals optimization
Lighthouse score improvement (30 to 90+)
Image compression and lazy loading
Code cleanup and minification
Mobile performance fixes
Before/after performance report

Ongoing work and maintenance

For sites that are live and need someone reliable to keep them fast and improving. Content updates, bug fixes, performance monitoring, and incremental improvements without the overhead of managing a developer.

Content and copy updates
Bug fixes and layout corrections
Performance monitoring
Monthly SEO health checks
Form and integration fixes
Site backups and uptime monitoring

General FAQ's

What kind of clients do you typically work with?

Founders, marketing teams, and agencies who need a site that works after launch, not just one that launches. I work best with people who have a clear problem and are ready to move.

What problems do you help businesses solve?

Most businesses struggle with websites that look outdated, load slowly, or fail to convert visitors into leads. I help solve these problems by designing and building high-performance websites that combine strategic design with clean development. The goal is to create a site that communicates your message clearly, builds credibility with your audience, and supports your marketing and growth goals.

What services do you offer?

I build custom Next.js and Framer websites, set up headless CMS systems (Sanity, Payload, Storyblok), build dashboards and client portals, fix performance issues, implement technical SEO, and publish Framer Marketplace components. If the project sits at the intersection of website and product, that's where I work best.

How does your process usually work?

Most projects follow a structured but flexible process. We begin with a discovery phase where we clarify goals, audience, and website structure. Then I move into design exploration and layout planning before building the site in Webflow or Framer. Throughout the process there are checkpoints for feedback to ensure the final product aligns with your vision and business objectives.

How long does a typical project take?

Project timelines vary depending on scope, but most websites take between two and six weeks from kickoff to launch. Smaller landing pages may take one to two weeks, while larger marketing sites or redesigns can take longer. I prioritize efficient workflows so projects move forward quickly without sacrificing design quality or performance.

Can you improve or rebuild an existing website?

Yes. Many of my projects involve improving or rebuilding existing websites that are slow, difficult to maintain, or no longer represent the brand well. I can redesign the experience, rebuild it in Webflow or Framer for better performance and scalability, and ensure the structure makes ongoing updates easier for your team.

Do you work with agencies or collaborate with teams?

Absolutely. I regularly collaborate with agencies, designers, marketers, and internal teams. In these cases I often focus on development or design implementation while integrating into your existing workflow. Clear communication and structured handoffs make collaboration smooth and efficient, allowing projects to move forward without unnecessary friction.

What makes you different from other web designers or developers?

I've been doing this for 7 years and I've seen what breaks after launch. I focus on building websites teams can actually operate, not just sites that look good on delivery day. Clean structure, real performance, and handoffs that don't require a developer to babysit.

Will I be able to edit the website myself?

That depends on the stack. Framer sites are editable out of the box. For Next.js sites, I set up a headless CMS or a lightweight editing layer so your team can update copy without touching the code. We figure out the right setup during the project.

What happens after the website launches?

I can stay on for ongoing work, or hand off cleanly with documentation. Most clients come back when something needs building or fixing. There's no retainer requirement.
