Web App Development

We build full-stack web applications from the ground up — frontend and backend chosen for the project requirements. Performance-first architecture means your app is fast, scalable, and ready to integrate with any third-party service.

Requirements First, Stack Second

We start with your requirements: what the app needs to do, who uses it, and how it needs to scale. The technology follows from that. Frontend and backend choices are made during scoping, with trade-offs explained and rationale documented.

Performance is non-negotiable. We instrument every application from day one: Core Web Vitals, Time to First Byte, and API response times are tracked in production throughout the life of the project. You get a web application that stays fast as it grows.

End-to-End Web Application Delivery

Full-Stack Architecture

Database schema, API design, server-side logic, and frontend component architecture planned together from the start. The frontend and backend are designed as one coherent system from the first planning session.

Frontend Architecture

Component-based UI built for maintainability and performance. Server-side rendering where SEO or load time demands it; single-page architecture where interactivity takes priority. Typed for team-scale codebases where the overhead is earned.

API & Integration Layer

REST and GraphQL APIs designed with versioning, authentication, and rate limiting from day one. Third-party integrations — payment gateways, CRMs, ERPs, webhooks — built with fault tolerance and graceful degradation so the app stays available.

Performance Engineering

Query optimization, caching layers (CDN, HTTP caching, in-process), lazy loading, and bundle analysis baked into the build process. Web Vitals targets are engineering requirements, measured in production.

Frequently Asked Questions

How much does web app development cost?

A focused web application typically starts at €8,000–€15,000 for a well-scoped MVP. Complex applications with custom backends, integrations, and multi-role user systems typically run €20,000–€60,000+. We scope every project in writing before a line of code is written — fixed-price scope agreed before work begins. The scope document becomes the contract.

What is the difference between a web app and a website?

A website is primarily informational — it presents content to visitors. A web application is interactive: users log in, manipulate data, trigger workflows, and see results that are specific to them. Examples include dashboards, booking systems, SaaS platforms, portals, and internal tools. The development complexity, architecture, and cost differ significantly.

How long does it take to build a web app?

A focused MVP typically takes 8–12 weeks from signed scope to production deployment. More complex applications with extensive integrations or multi-tenant architecture typically run 16–24 weeks. We provide a milestone plan at project start so progress is visible and delays are caught early.

What tech stack do you use for web app development?

The stack is chosen during scoping, based on the application’s performance requirements, data model, integration points, and your team’s existing tooling. We present the options with trade-offs before any code is written. Every recommendation comes with a rationale.
