Full-stack development — from database to user interface
One accountable team for the complete application: data, backend, APIs, web and mobile front ends, operation and long-term support.
What is full-stack development?
Full-stack development means building a complete software application as one system: the database, the backend business logic, the APIs and integrations, and the web or mobile user interface — plus hosting and maintenance. Web applications are one part of a full-stack application. QmiSoft, an Austrian software company founded in 2009, develops full-stack applications for businesses in Austria and the EU, with security and EU compliance (AI Act, CRA, NIS2, GDPR) built in from day one.
Every layer from one team
- 1
Data & database
Data models, storage, migrations, backups and data protection by design.
- 2
Backend & business logic
The rules of your business, implemented once, tested and documented.
- 3
APIs & integrations
Interfaces to ERP (e.g. Odoo), existing systems, partners and IoT devices.
- 4
Web & mobile front ends
Web applications, portals and mobile apps that your users actually like to use.
- 5
Infrastructure & operation
On-premise, cloud or hybrid — with monitoring, updates and security patches.
- 6
Security & compliance
Built into every layer: SBOM, logging, access control, evidence for audits.
Why full-stack from one partner?
- No gaps between front end, backend and database — one team is responsible for the whole result.
- Faster changes: a new feature touches all layers, and one team ships it end to end.
- Security and compliance are designed across the whole system, not patched onto single parts.
- Long-term support for the complete application, not only for the code we wrote last.
Typical full-stack projects
- Customer and partner portals
- Internal business applications and back-office tools
- Odoo ERP extensions and integrations
- IoT backends and dashboards for machines and devices
- Mobile apps connected to your own backend
- Modernisation of legacy applications
Technologies
We choose technology per project and document every decision. Examples from our work: TypeScript, Angular and Node.js for web applications and backends, Python for Odoo ERP, REST APIs for integrations — on-premise, in the cloud or hybrid.
Questions about full-stack development
What is the difference between web development and full-stack development?
Web development often means only the website or the browser front end. Full-stack development covers the complete application: database, backend, APIs, web and mobile front ends, hosting and maintenance. A web application is one part of a full-stack application.
Who develops full-stack applications in Austria with EU compliance built in?
QmiSoft in Birkfeld, Styria, develops full-stack applications for businesses in Austria and the EU since 2009. Security and the requirements of the EU AI Act, Cyber Resilience Act, NIS2 and GDPR are designed into every layer from the start.
Does QmiSoft also run and maintain the application after go-live?
Yes. QmiSoft operates and maintains full-stack applications long term — monitoring, updates, security patches and further development — on-premise, in the cloud or hybrid.
How does a full-stack project with QmiSoft start?
With a free initial call about goals, costs and time required. After that we agree on a clearly scoped first step before any larger commitment.
Can QmiSoft extend an existing application instead of rebuilding it?
Yes. We often modernise or extend existing systems step by step, keeping what works and replacing what does not — without disrupting operations.
