Christian Hutzinger
Last position:
Senior Full Stack Developer at Adria Magazin GmbH
Jesolo Tickets – Booking platform for tickets
Concept and implementation of a multi-tenant booking platform for the online sale of bus and ferry tickets in the Jesolo region (Northern Italy). Travel agencies and event organizers embed a customizable booking widget on their own websites; travelers check live availability, book multiple passengers, and pay online in just a few clicks.
- Real-time booking: Schedules and prices come live via the transport providers' API; after payment, the tickets are automatically delivered as QR-coded PDFs – with no manual issuance.
- Provider architecture: New providers can be onboarded without code changes; an origin-based multi-tenant model with its own domain and payment configuration for each partner site makes the platform grow with every customer.
- Clean architecture: 3-tier structure (handlers → services → data store) with caching – availability checks stay fast and maintainable even with many parallel requests.
Tech stack: Go, Echo, PostgreSQL (pgx), Stripe, Web Components, Tailwind CSS, esbuild, Docker, GitLab CI, Hetzner VPS

About the technology
API design
Swagger is widely used to describe and document REST APIs in a way that teams can read, test, and share. Strong specialists turn rough endpoint ideas into clear OpenAPI specs, then keep those specs aligned with the real service behavior.
Core tools
- Swagger UI for interactive API exploration
- Swagger Editor for writing and reviewing specs
- OpenAPI files for contracts and documentation
- Code generation for client and server stubs
- Validation checks for request and response shapes
Where it helps
Companies bring in Swagger specialists when API documentation has drifted, partner integrations are slowing down, or a new platform needs a clean contract from day one. It is also common in Austria-based product teams that work with distributed partners and need clear English documentation for internal and external use.
What strong specialists do
Good professionals do more than write a YAML file. They think about versioning, naming, error models, authentication flows, examples, and how the documentation will be used by other specialists. They also spot gaps between the contract and the implementation before they become support work.
Common project work
- Create or clean up OpenAPI specifications
- Set up Swagger UI for internal or public APIs
- Review existing docs against live endpoints
- Support API-first development workflows
- Improve handover for partner and client integrations
Skills around Swagger
Swagger work often sits next to REST, JSON, HTTP, authentication, and CI checks. Many projects also touch adjacent tools such as OpenAPI Generator, Postman, and testing frameworks that verify the contract. The best specialists keep documentation practical, consistent, and easy to maintain over time.
Frequently asked questions
Quick answers to the questions that come up most around Swagger.
Swagger is used to design, document, and test REST APIs through a clear contract. Teams use it to make endpoints easier to understand, validate, and hand over to other specialists.
Swagger is the name many people still use for the OpenAPI ecosystem. The format most teams work with today is OpenAPI, while Swagger UI and Swagger Editor remain common tools for viewing and editing the spec.
A strong Swagger specialist helps when API docs are missing, outdated, or hard to use. Companies also bring one in during API-first projects, partner integrations, or when multiple teams need one source of truth.
A good Swagger expert usually understands REST design, JSON, HTTP methods, status codes, and authentication. Practical experience with versioning, validation, and contract-driven workflows matters just as much as writing the spec itself.
Swagger focuses on the API contract and the generated documentation around it. Postman is often used more for testing and collection sharing, while RAML is another API description format that some teams prefer for specific workflows.
A Swagger project can be simple if it only needs a few endpoints documented, but larger systems need a specialist who can manage many resources, examples, and edge cases. The more integrations and teams involved, the more important structured API design becomes.
Yes, Swagger is well suited to remote work because the spec itself becomes the shared reference. In Austria, that is especially useful when product, backend, and partner teams work across locations and need clear documentation in English.
Look for clear OpenAPI files, realistic examples, consistent naming, and documentation that matches the live API. A good Swagger freelancer also asks about error handling, auth flows, versioning, and how the docs will be maintained after delivery.
