Web applications that grow with your business.
For teams that have outgrown off-the-shelf tools and spreadsheets. Custom applications, dashboards, customer portals and APIs on React, Go and PostgreSQL — the very stack this platform runs on, proven under load. Typical projects from 15.000 €.
A proven stack, not a technology lottery.
We don't chase the next hype framework — we use a stack we run ourselves every day. This platform is built with it. That means predictable performance, clean typing from the frontend down to the database, and code that's still maintainable in two years.
- Frontend: React, Next.js 15, TypeScript
- Backend: Go (Gin), cleanly separated service layers
- Data: PostgreSQL, Redis for cache & realtime
- Realtime: WebSockets, pub/sub
- DevOps: Docker, CI/CD, zero-downtime deploys

A custom web app vs. patchwork of tools.
Patchwork feels cheap — until the manual work and the licences add up.
Typical web apps.
What our stack looks like.
From concept to production.
Discovery & audit
We clarify the goal, users and data model, check feasibility and estimate scope honestly.
MVP sprint
The shortest path to a usable version. On staging, with progress visible daily.
Build-out
Feature by feature in clearly scoped sprints — with tests and code reviews.
Operations
Deploy with health checks and monitoring. We can take on ongoing maintenance if you want.
Common questions about web applications.
01What does it cost to have a web application developed?
The price depends on feature scope, integrations and user numbers — flat hourly rates say little. We work audit-first: in an audit sprint we estimate the effort honestly and you get a fixed-price offer with a clear deliverable, instead of an open-ended hourly account.
02How long does it take to build a web app or customer portal?
We start with an MVP sprint — the shortest path to a usable version — and build on it feature by feature in clearly scoped sprints. We fix the first delivery date in the offer.
03What's the difference between off-the-shelf and custom software?
Off-the-shelf software covers general needs but forces you into its processes. Custom web applications map your exact workflow, extend freely and are entirely yours — worth it as soon as standard tools hit their limits.
04Fixed price or time & material — which model fits my project?
We combine both: a fixed-price audit for a calculable start, then delivery in fixed-price sprints with a defined deliverable. Your budget stays predictable without carrying an open-ended hourly account.
05Which technologies do you use — React, Next.js, Go — and why?
Frontend with React, Next.js 15 and TypeScript; backend in Go with PostgreSQL and Redis. It's the same stack this platform runs on in production: predictable performance, clean typing and long-term maintainability over a hype framework.
06Can you take over and extend an existing project or legacy system?
Yes. We run a technical audit, read into the code, document the state and develop further — even with thin documentation or an outdated stack.
07How is my web application maintained and operated?
On request we handle hosting support, deploys with health checks, monitoring and ongoing updates. Alternatively we hand the repository and access over cleanly to your team — no lock-in.
08What's the difference between a web application, a website and a native app?
A website informs, a web application lets users work in the browser (login, data, workflows) and a native app is installed per platform. Web applications run anywhere without installation — ideal for portals, dashboards and internal tools.
09Is the web application GDPR-compliant?
Data protection is part of the architecture from the start: data minimisation, deletion and export functions, secure sessions and audit logs. We host in the EU on request. We agree the concrete scope per project.
What might still hold you back.
01You're a single founder — what if you're unavailable?
That's exactly why every project is built to be handed over: a standard stack instead of exotic tools, clean and tested code, documented architecture and deployment — and the repository is yours. Any competent developer can carry on without me. You're never chained to one person.
02Will the budget run away from me?
No. The project is cut into milestones with a fixed scope and a fixed price. You pay per milestone, get a working result after each one, and decide whether to continue. No open-ended hourly tab, no surprise on the invoice.
03Can one person deliver as fast as an agency?
Often faster. No coordination overhead, no ticket ping-pong, no friction between junior and senior — you talk directly to the person who builds. If scope grows, I bring in vetted partners selectively, always transparently agreed.
04What if I later want to continue in-house or with another provider?
Then you take the code, the docs and all access with you — it's yours anyway. I deliberately build in no dependency that locks you to me. Good work doesn't need a lock-in clause.
05What if our requirements change during development?
That's built in. Because we work in milestones, new insight flows in after each step — you see a working system early, not only at the end. Scope changes are discussed openly before they go into the next milestone.
