FAQ
Quick answers before we start.
Can you build both the frontend and integrations?
Yes. I can build the responsive frontend and connect forms, APIs, CRM tools, analytics, CMS workflows, payments or automation layers when the project needs them.
Is this service only for new websites?
No. I can also improve existing websites by rebuilding weak pages, fixing performance issues, restructuring content and adding missing technical SEO foundations.
Do you work with clients outside Ukraine?
Yes. I am based in Vinnytsia, Ukraine and work with clients worldwide through remote discovery, async updates and clear delivery milestones.
