Websites, funnels, and useful systems
Build the system your website should have been.
I design and build custom websites, landing pages, SEO/AEO surfaces, dashboards, and tools that turn attention into qualified action.
Proof before promise
Proof should move.
Every project starts with the same question: what is broken, what is it costing you, and what should the page or product make easier after launch?

What I build
No generic deliverables.
Each service is framed around the business symptom: missed leads, weak trust, slow pages, scattered operations, or paid traffic that lands flat.
See all servicesDoesn't represent your business? Fixed.
Your site doesn't represent your business. I build from scratch so it finally does.
Visitors leave? I make them stay.
Visitors leave before they buy. I design interfaces that keep them and convert them.
Ads running, no conversions? Fixed.
Ads running, no conversions. I build landing pages that turn clicks into customers.
When buyers ask, be the answer.
Search is changing from keywords to questions. I build pages that are crawlable, answer-ready, and connected to proof.
Data in five tabs? One screen.
Data scattered across five tabs. I build the one screen that shows you everything.
Slow site? I make it fly.
Slow site killing your conversions. I optimize until Lighthouse says 100.
Common problems
Search starts with the symptom.
Some buyers do not search for a deliverable. They search for the thing that feels broken. These pages connect that pain to the right service and proof.
Browse problemsSystem map
Four jobs. One flow.
Not a list of blocks. The page has to pull attention into proof, proof into offer, offer into action.
Demand
Acquire
Landing pages, SEO surfaces, and lead magnets.
Evidence
Prove
Case studies, speed, trust signals, and receipts.
Decision
Convert
Offer flow, checkout, inquiry paths, and follow-up.
Operations
Operate
Dashboards, automations, delivery tools, and cleanup.
How we work
From vague problem to shipped system.
The work moves in one direction: clarify the expensive problem, shape the interface, ship the system, then tune what happens next.
Understand
I dig into your problem, not just your wishlist. What's broken, what's costing you money, what needs to happen first.
Design
Wireframes and prototypes built for your specific problem. You see it before a single line of code is written.
Build
Fast, clean code. You get iterative updates, not a black box. If something's off, we catch it early.
Ship
Tested, optimized, deployed. Your project goes live and starts working for you.
The person behind Volt
One person. Full context.
Discovery, design, code, launch, and the uncomfortable business questions stay in one head from start to finish.
I grew up between music school and computer science. While studying at the Zagreb Academy of Music, I was already building websites, automations, and small tools on the side.
In 2022, I opened M Street Music, a recording studio in Krapina. Running it taught me the business side: leads, broken workflows, slow admin, and tools that waste attention.
Volt comes from that place. I build practical systems because I know what it feels like when a page, process, or product has to start earning its place.
Music school, studio ownership, teaching, software, and client operations all feed the same practical instinct: find what is broken and ship the useful fix.
Ship & Get PaidProof and stack
Proof does not need a grid of badges. It needs signal: what shipped, what improved, and what people say after using it.
Specific beats generic.
“Kristijan is a true professional and expert.”
“If there were infinite stars, every single one would go here.”
“Highly recommended!”
FAQ
Questions are cheaper before build.
The page should answer objections without turning into a support center. These stay fast, plain, and close to the buying moment.
Contact

Send the problem. I will answer with the path, the first version, and what has to be true after launch.
