Fred Hauschel
Last position:
Software Architect and Developer at Personal project
A recurring problem in my own AI-supported projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but they remain hard to trace and scattered across Markdown files – knowledge is lost as soon as it is no longer in the context window. arknet turns requirements engineering and architecture knowledge into structured, verifiable data instead of plain text: requirements, use cases, and architecture decisions as a continuously linked knowledge graph, traceable from the requirement to the architecture decision – queryable for both people and AI agents alike. Technically based on RDF/OWL and its own MCP server.
Result: MCP daemon running, Docker image automatically published on GHCR, nine hexagonal modules, eleven ADRs (including an open-core licensing model). Requirements engineering and ubiquitous language hexagon active. Publicly available since 07/2026 as a Community Edition under Apache-2.0 (github.com/kogn-io/arknet), together with the Claude Code plugin and the GHCR image; open-core model.

Full Stack Lead Developer, Backend Architect at Telefonica (O2)
The software supports the complete planning and approval of antennas for mobile telephony.
The system was implemented using an event-driven microservice architecture for cloud-native deployment with Quarkus on the backend, Kafka for communication, and Angular for the frontend. Services run on Kubernetes in Google Cloud. A special challenge was synchronizing with the legacy system still used by some users.

About the technology
Database migrations
Flyway is used to version and apply database changes in a controlled way. It helps teams keep schema updates repeatable, traceable, and aligned with application releases. That matters when many experts touch the same database over time.
Common tasks
- Write versioned SQL migration scripts
- Set up baseline and repair workflows
- Review migration ordering and naming
- Handle rollback-safe change plans
- Connect database changes to CI/CD
Ecosystem fit
Flyway works with Java stacks, Spring Boot, build tools, and release pipelines. It also fits teams that use PostgreSQL, MySQL, SQL Server, Oracle, or cloud databases. Strong specialists know how Flyway fits into the wider delivery process, not just the script folder.
When to bring in help
Companies usually bring in freelance expertise when database changes are slowing releases, migration history is messy, or multiple environments no longer match. In Munich, this often comes up in product teams, enterprise software groups, and companies modernizing legacy systems. A specialist can stabilize the process without rewriting the whole stack.
What strong experts do
Strong Flyway professionals keep migrations small, predictable, and safe to rerun. They understand script versioning, checksum issues, environment parity, and how to test database changes before release. They also document decisions so other experts can maintain the setup later.
Delivery focus
The best engagements end with clean migration files, a clear release flow, and fewer surprises in production. Depending on the setup, that can include fixing broken histories, introducing team conventions, or preparing a database change process for a new service. Flyway is often the difference between ad hoc SQL and a release process the whole team can trust.
Frequently asked questions
Questions about Flyway? Start with the answers below.
Flyway is used to manage database migrations in a controlled, repeatable way. Teams use it to apply schema changes, keep environments aligned, and track which updates have already run. It is common in application delivery where database changes must move with code.
Flyway is usually chosen when teams want a simpler, script-first migration flow. Liquibase is more flexible in how changes are described, but it can feel heavier for teams that prefer plain SQL. The right choice depends on how much structure the team wants around database change management.
A strong Flyway specialist should be comfortable with SQL, schema design, and the database engine used in the project. Knowledge of CI/CD, testing, Java or Spring Boot, and release workflows is also valuable. The best experts think about deployment risk, not only script syntax.
A project usually needs Flyway help when migrations are failing, environments have drifted apart, or releases depend on manual database work. It is also useful when a team is introducing database versioning for the first time. External experts can set up the process quickly and leave the team with clear conventions.
Yes, Flyway is commonly used with Spring Boot and other Java-based systems. It fits well into build and release pipelines where migrations should run alongside application changes. Many teams also use it in microservices and larger enterprise applications.
For a small setup, a Flyway freelancer with solid practical experience can be enough. For a complex landscape with many databases, strict release windows, or legacy data rules, you want someone who has handled production migrations before. The key is real delivery experience, not just tool familiarity.
Yes, Flyway work is often done remotely because most tasks are script review, pipeline setup, and coordination with the team. On-site time can still help when access, governance, or legacy database knowledge is concentrated in Munich. Many projects work best with a mix of remote delivery and a few focused workshops.
Look for clear migration naming, safe change design, and good handling of rollbacks, baselines, and repairs. A strong Flyway expert can explain why a migration is ordered a certain way and how it will behave in staging and production. Good communication matters as much as tool knowledge, because database changes affect the whole release flow.
