Web solutions that move your business forward

Modern business starts online. We build web applications and websites that don't just look great — they generate leads, increase sales and scale with your business. Our approach combines leading-edge technology with a deep understanding of business goals.

What we build

SaaS platforms

Full-featured cloud applications for your business:

  • Multi-tenant architecture: efficiently serving thousands of users with data isolation.
  • Subscriptions and billing: integration with Stripe and payment providers, and automated invoicing.
  • Admin panels: powerful dashboards for managing content, users and analytics.
  • API-first approach: flexible architecture for integrating mobile apps and external services.

E-commerce solutions

Online stores that sell:

  • Product catalogues: a flexible management system with filters, search and categories.
  • Optimised checkout: minimising drop-off at the order stage.
  • Payment integrations: Stripe, PayPal and other providers.
  • Inventory and logistics: stock synchronisation and delivery tracking.

Corporate websites and landing pages

Websites that deliver results:

  • Corporate portals: full-featured brand presence.
  • High-converting landing pages: optimised for advertising campaigns.
  • Media portals and blogs: SEO-optimised content management systems.
  • Customer portals: self-service portals for your users.

Key benefits

Loading speed Our sites load in 1–2 seconds thanks to server-side rendering, image optimisation and CDN. A fast site can convert up to 70% better than slow competitors.

SEO optimisation Technical SEO is built into the architecture from day one: semantic markup, structured data, and Core Web Vitals in the green. Clients report organic traffic growth of 40–120% in the first six months.

Responsive design Every project is optimised for mobile, tablet and desktop. With over 60% of traffic coming from mobile, this is critical for business.

Accessibility (a11y) Compliance with WCAG 2.1 — your product is accessible to all users, widening your audience and reducing legal risk.

Security Protection against the OWASP Top 10, data encryption and regular security audits. Your data and your customers' data are well protected.

Scalability Architecture ready to grow: from hundreds to millions of users without rewriting the codebase.

Technologies we use

  • Frontend frameworks: React, Next.js, Vue.js, Svelte, Astro.
  • Styling and UI: Tailwind CSS, Framer Motion, Radix UI, shadcn/ui.
  • Backend: Node.js, Express, tRPC, Prisma.
  • Databases: PostgreSQL, Redis, MongoDB.
  • Infrastructure: Vercel, AWS, Docker, CI/CD pipelines.
  • Languages: TypeScript (full-stack), Python for integrations.

How we work

  1. Analytics and strategy: research your target audience and competitors, define the technical brief and architecture, set KPIs (conversion, speed, engagement), and build prototypes and a design concept.
  2. Design: UX research and user journeys, interface design in Figma with responsive layouts, a design system and UI kit, and iteration with your team.
  3. Development and testing: agile development in two-week sprints, code review and automated testing, performance optimisation at every stage, and a progress demo after each sprint.
  4. Launch and scaling: smooth deployment with metric monitoring, A/B testing of key elements, analytics and conversion optimisation, and ongoing technical support and development.

Use cases

  • SaaS and startups: an MVP to attract investment in 8–12 weeks, platform scaling as the user base grows, and integration with analytics and marketing tools.
  • E-commerce and retail: online stores converting 30–50% above industry standards, multi-vendor marketplaces and aggregators, and omnichannel solutions synchronising online and offline.
  • Corporate: portals for companies with 1,000+ employees, customer portals and partner programmes, and internal tools and leadership dashboards.
  • Media and content: high-traffic content platforms, educational portals with course systems, and media sites with optimised content delivery.
