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.

About the technology
Enterprise Java Development with Spring Boot
This framework simplifies the creation of production-ready Java applications. By providing default configurations and embedded servers, it eliminates boilerplate setup, allowing businesses to launch robust web services quickly. It serves as the backbone for modern enterprise backends, handling high-volume transactions and complex business logic with ease.
Core Ecosystem and Technical Capabilities
Modern enterprise projects require mastery of a broad suite of tools integrated within the Java platform. Specialists utilize these modules to build scalable architecture.
- Spring Data JPA for seamless database integration and management
- Spring Security for robust authentication and OAuth2 authorization
- Spring Cloud for configuring resilient microservices and service discovery
- Integration with containerization tools like Docker and Kubernetes
- Connection to message brokers such as Apache Kafka and RabbitMQ
Local Munich Industry Applications
The Munich business landscape demands highly secure and scalable software solutions. Local automotive leaders, financial institutions, and fast-growing B2B software companies rely heavily on this ecosystem to power their digital platforms. Specialists operating in this region understand the high standards of security and performance required by these established German industries.
When to Onboard External Specialists
In-house teams often face capacity bottlenecks or lack the specific knowledge needed for complex transitions. Bringing in external expertise helps accelerate timelines and ensures architectural best practices.
- Migration of legacy Spring Framework monoliths to cloud-native microservices
- Performance tuning of slow database queries and memory leak resolution
- Setting up secure API gateways for external partner integrations
- Implementing modern reactive programming models with Spring WebFlux
Remote and On-Site Collaboration in Bavaria
Many companies in Munich prefer a hybrid working model, combining productive remote sprints with regular on-site alignment meetings. Having specialists nearby simplifies face-to-face workshops for system architecture planning or security audits. Effective communication in both English and German ensures seamless integration into local corporate structures and development teams.
Key Qualifications of Elite Professionals
Outstanding specialists possess a deep understanding of Java internals and JVM tuning. They do not just write functional code; they design clean, maintainable systems that adhere to solid design principles. They are comfortable navigating CI/CD pipelines, automated testing strategies, and cloud infrastructure, ensuring that the software runs reliably in production environments.
Frequently asked questions
Quick answers to the questions that come up most around Spring Boot.
The core benefit of Spring Boot is its ability to accelerate the development of production-ready Java applications through auto-configuration and starter dependencies. It reduces boilerplate code significantly, allowing teams to focus on business logic. This makes it the preferred choice for enterprise systems that require high reliability and scalability.
A highly qualified Spring Boot specialist demonstrates deep knowledge of the core Spring Framework, transaction management, and dependency injection. Look for professionals who are proficient in writing unit and integration tests using JUnit and Mockito. Their ability to optimize database queries and configure database connection pools is also a strong indicator of technical maturity.
Beside core Spring Boot expertise, specialists should be familiar with container technologies like Docker and orchestration platforms like Kubernetes. In the Munich market, experience with cloud platforms such as AWS or Microsoft Azure is highly sought after. Knowledge of modern continuous integration and deployment pipelines is also essential for seamless delivery.
While many Spring Boot projects can be executed entirely remotely, many Munich-based companies prefer a hybrid model. Local professionals can easily join critical on-site workshops, architecture planning sessions, or sprint planning meetings in the city. This hybrid approach often builds stronger trust and ensures smoother alignment with internal stakeholders.
While the Spring Framework provides comprehensive infrastructure support for Java applications, configuring it manually requires extensive XML or Java setup. The newer framework pre-configures these settings out of the box, allowing rapid setup. Essentially, it wraps the original ecosystem to make application startup much faster and simpler.
Compared to newer microservice frameworks, Spring Boot benefits from a massive ecosystem, extensive documentation, and a huge pool of available talent. While frameworks like Quarkus or Micronaut offer faster startup times and lower memory footprints, this technology remains the industry standard for enterprise applications due to its unparalleled stability and rich feature set.
For most Spring Boot projects in Munich, English is the primary language used in development teams and codebase documentation. However, fluent German is often highly advantageous, especially in traditional industries like banking, insurance, and automotive. Having bilingual professionals helps bridge communication gaps between business departments and technical teams.
The timeline depends heavily on the project scope, but typical enterprise contracts for Spring Boot integration or migration run from three to nine months. Mid-sized projects, such as building a single microservice, can often be completed in a few weeks. A professional specialist can quickly assess the requirements and provide a realistic estimate for the delivery milestones.
The average hourly rate of freelancers in Munich, Germany who have used Spring Boot in their recent projects is 92 €, which corresponds to a daily rate of about 738 € based on an 8-hour working day.
