// COMPLEX_WEB_DEVELOPMENT
WEB APPLICATIONS THAT GO BEYOND A PAGE
We do not build corporate websites. We build complex web applications with scalable architectures, optimised performance and clean code. React, Next.js, robust APIs and cloud-native infrastructure. No WordPress. No Shopify. Just real code.
// DETAILED_DESCRIPTION
When we talk about complex web development, we mean applications that go far beyond a presentation page. Multi-tenant SaaS platforms, e-commerce with advanced business logic, B2B portals with roles and permissions, real-time data dashboards and management systems accessible from the browser.
Our technology stack centres on the modern JavaScript/TypeScript ecosystem: React and Next.js on the frontend, Node.js and Python on the backend, PostgreSQL as the primary database and Docker for reproducible deployments. Every project is built with CI/CD from day one, automated testing and production monitoring.
We do not use site builders, premium themes or third-party plugins. Every component is designed, coded and tested from scratch. The result is a fast, secure, maintainable application that is entirely yours — no vendor dependencies, no recurring licence costs.
// CAPABILITIES
SPA & SSR Applications with React
Single Page Applications with React for maximum interactivity, or Server-Side Rendering with Next.js for SEO and performance. We choose the right architecture for each use case.
RESTful & GraphQL APIs
Robust backends with Node.js, Express, Fastify or Python FastAPI. APIs documented with OpenAPI/Swagger, versioned and secured with JWT/OAuth2 authentication.
Multi-tenant Platforms
SaaS architectures where multiple clients share infrastructure with fully isolated data. Row Level Security, custom subdomains and billing plans.
Advanced E-commerce
Online stores with complex business logic: dynamic pricing, product configurators, subscriptions, marketplaces and multi-step Stripe checkouts.
Cloud-Native Infrastructure
Deployments on AWS, GCP or your own servers with Docker, Kubernetes, CDN and auto-scaling. CI/CD with GitHub Actions, monitoring with Grafana and centralised logging.
Performance & Accessibility
Optimised Core Web Vitals, lazy loading, code splitting and aggressive caching. WCAG 2.1 AA accessibility across all interfaces. Lighthouse 90+ guaranteed.

// FAQ
Why don't you use WordPress or Shopify for web development? +
WordPress and Shopify are excellent tools for blogs and simple shops, but they have serious limitations for complex applications: performance, security, scalability and flexibility. When you need custom business logic, deep integrations or multi-tenant architectures, bespoke code is the only serious option.
How much does it cost to develop a complex web application? +
A web application with authentication, admin panel and basic functionality starts from 15,000-25,000 EUR. Complete SaaS platforms, advanced e-commerce or portals with multiple roles typically range from 40,000-120,000 EUR. We always provide a fixed quote after the initial analysis.
What about maintenance after launch? +
We offer monthly maintenance plans that include security updates, bug fixes, performance optimisation and minor feature enhancements. The code is 100% yours — if you prefer to maintain it internally, we deliver complete documentation and training.
Can I see progress during development or do I have to wait until the end? +
We work in 2-week sprints with demos at the end of each one. From the first week, you have access to a staging environment where you can see progress in real time. We use GitHub for code and Notion/Linear for project management, all with full access for you.
