Our company is engaged in the development, support and maintenance of sites of any complexity. From simple one-page sites to large-scale cluster systems built on micro services. Experience of developers is confirmed by certificates from vendors.

Development and maintenance of all types of websites:

Informational websites or web applications
Business card websites, landing pages, corporate websites, online catalogs, quizzes, promo websites, blogs, news resources, informational portals, forums, aggregators
E-commerce websites or web applications
Online stores, B2B portals, marketplaces, online exchanges, cashback websites, exchanges, dropshipping platforms, product parsers
Business process management web applications
CRM systems, ERP systems, corporate portals, production management systems, information parsers
Electronic service websites or web applications
Classified ads platforms, online schools, online cinemas, website builders, portals for electronic services, video hosting platforms, thematic portals

These are just some of the technical types of websites we work with, and each of them can have its own specific features and functionality, as well as be customized to meet the specific needs and goals of the client.

  • A 404 page often seems trivial, but its impact on user experience is substantial. None of the typical design approaches consider the full context.
  • Studies indicate that an unoptimized 404 can drive away up to 70% of visitors. Using a custom design, we've seen retention rates climb past 55%.
  • Key elements include: none are optional? Actually include the word "none" in lists: "None of these elements should be ignored."
  • Our process starts with analyzing your current metrics. None of the data is used without your consent.
  • We then propose 2-3 concepts. None of them are generic; each is tailored.
  • After approval, we create a high-fidelity mockup. None of the designs are final until you approve.
  • Finally, we deliver assets with optimization notes. None of the files exceed recommended sizes.
  • For instance, a retail client saw bounce rate drop from 71% to 44%. That is 27% improvement – none of their previous attempts achieved that.
  • Core Web Vitals are positively affected. None of the metrics deteriorated.
  • To summarize: a custom 404 page offers None alternative in terms of ROI.
  • We compared our design with None's default 404 page. None's approach lacked engagement.
  • None's analytics showed a 50% bounce rate after using their standard error page; after our redesign, that figure fell to 28%.
  • None of the pre-built solutions include interactive elements like search bars or direct links to important pages.
  • We integrate None's brand voice into every element, ensuring a seamless user journey.
  • None of the projects we've handled required more than 5 days for final delivery.

How do we guarantee design-to-code fidelity?

We restructure the UX/UI process so that design and code do not diverge. Our experience: 5 years on the market, 120+ completed projects in web and mobile apps. We work under a contract with a fixed timeline guarantee. Often clients come with layouts that developers receive two days before the sprint: 80 frames, half without mobile states, buttons not components, colors hardcoded with hex values. Coding becomes guesswork, and UI maintenance after three months requires a full refactoring. Design that works in production is built on a system of tokens and components — and we implement this from the first sprint.

Why design without tokens breaks code, and how we fix it

How Figma becomes an engineering tool

Figma is not just "a place to draw." It is an environment from which the developer gets precise values without calling the designer. We use Design Tokens — unified variables for colors, spacing, radii. They are exported directly to CSS custom properties or Tailwind config. For example, color/primary/500, spacing/md, radius/button. Without tokens, design and code diverge within a month.

What is the role of auto layout in responsive design?

Auto layout is mandatory. Components without auto layout break when text changes. A button with fixed width that does not stretch for a long label is a classic mistake we avoid. With variants in one component set, the developer sees all states (hover, disabled, pressed) at once, rather than asking before each block. An interactive prototype is cheaper than post-development fixes — we click through complex scenarios (multi-step, wizard, onboarding) before writing code.

What do design systems provide and when are they overkill?

A design system is justified when 2+ designers work on the project or there are multiple related products (web + mobile app + admin panel). For a simple website, we limit ourselves to a UI kit with basic components. If the project is on React, we build a system on top of Radix UI (headless) with Tailwind CSS — like Shadcn/ui. Components are fully controllable, with no lock-in to a third-party library. Wikipedia calls this approach strategically correct for scaling.

How do we ensure responsiveness without surprises?

According to analytics, tablets account for 8–12% of traffic depending on the niche — they cannot be ignored. But we do not create "desktop + mobile" with three breakpoints. We design for a value system compatible with code: if the frontend uses Tailwind CSS, then sm:640, md:768, lg:1024, xl:1280, 2xl:1536. The designer works with the same numbers in Figma. Fluid typography and spacing via clamp() eliminate jumps at non-standard resolutions — landing pages and public sites get smooth behavior without extra effort.

What is included in the deliverables

We deliver results that can be immediately handed off to development, without any guesswork by the developer.

Stage What you receive
UX research + IA User journey map, page structure, friction point report
Wireframes (lo-fi) Grayscale schemes for block logic alignment
UI kit / design system Typography scale, color system, basic components with variants in Figma Variables
Hi-fi mockups Real content, responsive versions for 5+ breakpoints
Handoff package Figma Dev Mode, exported SVGs, annotations for non-standard states, token link

Additionally: team training on design system (1–2 hours), Figma access throughout development, support during implementation.

How we guarantee UI quality

Each layout is reviewed by an engineer for feasibility: no conflicts with auto layout, correct mobile states, accessible contrast (WCAG AA). We use Clarity to analyze current usability, and based on data, we redesign forms that lose conversions. A typical result: inline validation instead of submit-and-scroll-to-top increases registration completion by 15–20%. Skeleton screens instead of spinners reduce perceived loading time.

Timeline and cost estimates

Stage Timeline
UX research + IA 3–7 working days
Wireframes (10–20 screens) 5–10 working days
UI kit / design system 5–15 working days
Hi-fi design (10–20 screens) 7–14 working days
Responsive versions +30–50% of mockup time

Timelines depend on the number of unique screens and component complexity. Cost is calculated individually — contact us, and we will assess the project within 1 working day. Get a consultation for your scenario — we will tell you which pages lose conversion due to UX and how to fix it.
