How long does a typical web app project take?

It depends on the scope. Scope, price and schedule are fixed in writing before anything is built; the project configurator gives you a ballpark figure in advance. During development you regularly get interim versions you can try yourself.

What happens when traffic grows?

A bigger server is usually enough at first. As load keeps growing, a cache (Redis), a read replica of the database and several app instances behind a load balancer are added. The architecture is prepared for this from the start without raising the initial effort.

How are database changes rolled out?

Every schema change is a versioned Alembic migration. It is applied in the test environment and rolled back there once before it goes to production. That way the way back has been rehearsed before it is needed.

Web App Development

We build web applications that keep running not just in the demo but after years in production: typed code, automated tests, monitoring and backups whose restore has been rehearsed. From the first prototype to a platform with customer accounts and billing.

The Techlogia Lab learning platform in the browser: check result with explanation next to the live terminal of a real Linux VM

Where you can check it

See it in the Techlogia Lab

A learning platform where every lesson starts a real Linux VM in the browser. A checker reads the state of the machine and tells you within seconds what is still missing.

Behind the Lab are the same building blocks we use for clients: an admin area where almost all content is maintained without a developer, roles and permissions, payments via Stripe and a one-click data export under Art. 15 GDPR. techlogia.de itself runs on this architecture too.

What clients bring us in for

Customer portal with accounts and billing

Login, roles, separate data per customer, recurring payments via Stripe and an admin area for your team. GDPR data export and deletion are built in, not bolted on.

Internal tools and reporting

Data from several sources in one place, with filters, export and role-based permissions – often replacing a spreadsheet that grew out of control. Runs on your server, with no per-user fee.

Content your team edits without a developer

Website, blog or catalog with its own admin area where your team changes texts, images and pages. techlogia.de is maintained exactly this way.

Tech: Next.js 15, React, TypeScript, Tailwind CSS, Python, FastAPI, MariaDB, PostgreSQL, Redis, Docker, Nginx

How we work on it

Fixed interfaces instead of surprises

Pydantic schemas in the backend, TypeScript in the frontend and tests that pin down the interface. If it drifts, that shows up before release, not with your customers.

Releases through a quality gate

A new version only goes live once the automated tests against a real database pass – first in the test environment, then in production. Our own platform is released the same way.

Hosted where you want

Hetzner servers in Germany, your own infrastructure or another provider: the application runs in Docker containers and can be moved. No tie to our servers.
