Specialist services

Focused solutions for your product and operational workflows.

Next.js development

We build Next.js websites and applications for businesses that need a clear customer journey, indexable content and a maintainable codebase. We work on new products and existing React applications.

Telegram Mini App development

We build a connected product inside Telegram: Mini App, bot, backend and admin tools. The starting point is the user journey and the team's operations, so entry points, notifications and data work together.

/ questions

What to know before starting

Can you improve the interface without rewriting the product?

Yes. Start with critical workflows and component boundaries, agree compatibility with the current API and migrate screens incrementally. A full replacement needs a reason strong enough to justify the migration cost.

How do you verify interface quality?

We check responsive layouts, keyboard navigation, loading and error states, core user actions and performance on agreed devices. Public pages also receive server-rendered content and SEO checks.

Can you work from an existing design?

Yes. We review principal screens, mobile states, interactions and components before estimating. Missing error, empty and long-content states are agreed with the team.
