Pascal Krason · Application development & systems integration

Build the software. Run the infrastructure. One point of contact.

Laravel, React and Go for the application. Hetzner, Docker and deployment pipelines for operations. For agencies that need capacity, startups building a product, and companies with real technical needs.

Pascal Krason

10+ years of backend engineering and systems architecture

Services

Two areas, one point of contact.

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, hardware protocol, service regulation
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 a project

Systems integration & operations

The application runs on infrastructure I build, deploy to and look after – 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

Who I work with.

Three situations that end up in my inbox.

Agencies

A Laravel or React project is sold, your backend team is at capacity.
A client project needs infrastructure, deployment and someone who is reachable.
White-label on request: 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 projects, three rulebooks.

Cashless vending, billing by statute, shift planning by regulation. What I built and what came out of it.

Konteo Management Panel

Coin mechanisms and prepaid cards per machine do not scale across beverage fleets: cash has to be collected and balances reconciled machine by machine.

CuraBill

VBVG 2026: 16 remuneration combinations, deadlines under the BGB, a 15-month filing limit. For professional guardians, hardly possible to bill by hand without errors.

Duty rosters on paper, swaps by word of mouth, operational readiness checked by hand. Roles and duties are set by the BayFwDV.

Who is behind it

A developer who also knows the infrastructure.

I am Pascal Krason, backend engineer and systems architect for more than ten years. 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.

Tell me briefly about your project.

Three required fields, two minutes. I reply within 24 h (business days), followed by a short call of about 30 minutes. No pitch deck, no obligation.
