About

We don't make pretty sites — we make things that work.

We start where most agencies stop: with your business model, your audience, and your distribution. Only then do we open a design tool.

Every site we ship is performance-optimized, SEO-ready, and built to last. No throwaway templates, no trendy fluff — just systems that earn their place.

Everything included. Nothing hidden.

Every engagement comes with a complete set of deliverables. We define scope before we start, and we don't charge for scope we promised.

01 Site Structure
+
Sitemap, hierarchy, internal linking — built before design. You see exactly where every page lives and why, before a single pixel is placed.
02 Interface Design
+
All screens in Figma: desktop, tablet, mobile. Component library included. You approve before we build.
03 Mobile Version
+
Separate layout for thumb navigation, not a scaled desktop. Touch targets, swipe patterns, and performance are all considered independently.
04 Integrations
+
CRM, analytics, forms — connected and tested before launch. We verify every data flow with real test submissions, not dummy data.
05 SEO Launch Setup
+
Meta, sitemap, robots.txt, structured data — day one ready. Search Console verified, indexing confirmed, no "we'll do it later" loose ends.
06 Post-Launch Support
+
30 days fixes included. Growth retainer available after. We stay close while things settle, because launches always surface edge cases.

Common questions.

How long does a project take?
+
Landing 1–2 weeks. Multi-page 3–6. International 6–12. Timeline fixed before start.
How do we start?
+
Send a brief. We reply in 24h and send a proposal. No calls required.
Do you write copy?
+
We provide structure. Copywriting available as add-on.
Russian and English?
+
Yes. Proper hreflang and separate SEO per language.
What after launch?
+
30 days support included. Monthly growth retainer after.
Can you redesign our existing site?
+
Yes. We audit first, then propose what to keep, fix or rebuild.
