Pascal Krason · Freelancer for application development & systems integration
Build the software. Run the infrastructure. One point of contact.
I build web applications with Laravel, React and Go and run the infrastructure they live on – Hetzner Cloud, Docker, deployment pipelines. For agencies that need capacity, startups building a product, and companies with real technical needs.

Services: Development and operations from one source.
I build the application and make sure it runs – no handover between development and operations.
Application development
Web applications, admin panels and APIs that model business rules correctly – even after the next legal change or firmware release.
- Web applications and admin interfaces with Laravel and React/Inertia (TypeScript)
- REST APIs with OpenAPI specs and token scopes for partner systems and devices
- Business logic with the rulebook as a test suite: statute (VBVG), hardware protocol (ESP32 vending machines), service regulation (BayFwDV)
- Multi-tenant SaaS platforms and integrations (Amazon, DHL, Excel import, ESP32 devices)
- Desktop and hardware tools in Go (NFC/RFID, macOS, Windows, Linux)
Typical: PHP 8 · Laravel · React · Inertia · TypeScript · Go · MariaDB/MySQL · Redis
Request an application projectSystems integration & operations
I build the infrastructure, put the application into production and look after it – one contact instead of a handover to “the hosting company”.
- Cloud infrastructure and operations: Hetzner Cloud, Linux, Docker, Nginx, Kubernetes
- Deployment pipelines with GitHub Actions, provisioning with in-house tooling
- Databases, queues and workers in production: MariaDB/MySQL, Redis, Laravel Horizon
- Monitoring, backups, updates and security patches – on request with on-call outside office hours
- Taking over and stabilising existing systems, migrating between hosting providers
Typical: Hetzner · Linux · Docker · Nginx · Kubernetes · GitHub Actions

Typical situations: For agencies, startups and companies.
Three situations that end up in my inbox.
Agencies (white-label too)
- A Laravel or React project is sold, your backend team is at capacity.
- A client project needs infrastructure, deployment and someone who is reachable.
- On request as a subcontractor in the background: your client only sees you.
Startups
- From prototype to product: backend, API and infrastructure from one source while the team works on the product.
- Add tenants, roles and an audit trail before the first enterprise customer asks.
- Devices in the field that need to talk to a backend.
Companies
- A process with a fixed rulebook should become software: billing, shift planning, device fleet.
- Internal tools and admin panels that replace Excel and paper.
- An existing application runs, but nobody looks after the infrastructure.
References: Three Laravel projects, three rulebooks.
Cashless vending, billing by statute, shift planning by regulation. Each reference covers the project, its features and the challenges.
Who is behind it: A developer who also knows the infrastructure.
I am Pascal Krason, an independent backend engineer and systems architect with more than ten years of experience. I build applications whose rules cannot be broken – billing by statute, devices in the field, shift plans by regulation – and run the infrastructure they live on. Alongside client work I develop my own products such as Konteo.
Request a project: Tell me briefly about your project.
I reply within 24 h (business days), followed by a short call of about 30 minutes. No obligation.
