Fred H.
Last position:
Software Architect and Developer at Personal project
Recurring problem in my own AI-assisted projects: requirements analysis, use cases, and architecture decisions can be created quickly with AI support, but remain difficult to follow 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 form a consistently linked knowledge graph, traceable from requirement to architecture decision – queryable by both people and AI agents. Technically based on RDF/OWL and a custom MCP server.
Result: Working MCP daemon, Docker image published automatically to GHCR, nine hexagonal modules, eleven ADRs (including an Open-Core licensing model). Requirements engineering and Ubiquitous Language hexagons are active. Public as a Community Edition under Apache-2.0 since 07/2026 (github.com/kogn-io/arknet), together with the Claude Code plugin and GHCR image; Open-Core model.

Bela B.
Last position:
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
Security for Spring applications
Spring Security is the security framework for Spring-based applications. It protects web applications, REST APIs and service-to-service communication through authentication, authorization, session controls and security filters. Specialists configure it to fit the application's identity model instead of adding isolated checks throughout the codebase.
Authentication and access
Professionals use Spring Security to connect applications with enterprise identity systems and external identity providers. Typical work includes:
- Configuring form login, HTTP Basic and stateless token authentication
- Integrating OAuth2 and OpenID Connect providers
- Defining roles, scopes and method-level authorization
- Protecting REST endpoints and browser sessions
Ecosystem and tooling
The framework works closely with Spring Boot, Spring MVC, Spring WebFlux and Spring Authorization Server. Strong specialists understand JWT validation, opaque tokens, LDAP, SAML, CSRF protection, CORS and password encoding. They also use automated tests to verify access rules across controllers, services and reactive pipelines.
When companies need support
Freelance expertise is useful when a team is replacing custom login code, introducing single sign-on or exposing existing services through APIs. It also helps during migrations from older WebSecurityConfigurerAdapter patterns to the current bean-based configuration model. In Munich, this work often connects with enterprise Java systems and regulated business applications, where access decisions must be clear and auditable.
Delivery and collaboration
A capable professional begins by mapping users, applications, data and trust boundaries. They document authorization rules, define failure handling and test both permitted and rejected requests. Remote collaboration works well when repositories, identity-provider environments and acceptance criteria are available; on-site sessions can help when security policies involve several local teams.
What strong specialists bring
Look for hands-on experience with the exact Spring Security generation used in the project, not just general Spring knowledge. A strong specialist can explain filter-chain order, distinguish authentication from authorization and review token claims critically. They leave maintainable configuration, security tests and operational guidance rather than a collection of opaque rules.
Frequently asked questions
Need clarity? These are the questions we hear most often about Spring Security.
Spring Security protects Spring applications and APIs from unauthorized access. It handles authentication, authorization, session security, password protection, OAuth2 and OpenID Connect integration, as well as common web security controls.
Spring Security provides established filters, extension points and integrations instead of requiring a team to maintain security logic from scratch. Custom code may still be needed for unusual policies, but the framework reduces duplicated controls and makes security behavior easier to test and review.
A strong Spring Security specialist should also understand Spring Boot, Spring MVC or WebFlux, OAuth2, OpenID Connect, JWT validation and REST API design. Experience with LDAP, SAML, cloud identity providers, databases and automated security testing is valuable when the application has enterprise access requirements.
The required level depends on the risk and integration scope. A straightforward policy change may suit a professional familiar with Spring Boot, while identity-provider migration, authorization redesign or reactive security calls for a specialist who has delivered comparable systems and can explain the security model clearly.
Yes. Spring Security supports OAuth2 client and resource-server patterns and can validate tokens issued through OpenID Connect providers. A specialist should confirm issuer configuration, scopes, claims, token expiry, logout behavior and the separation between user authentication and API authorization.
Yes, much of Spring Security configuration and testing can be completed remotely with secure access to code, test identity providers and deployment environments. On-site workshops may help when Munich-based teams must align on internal policies, access ownership or integrations that cannot be exposed outside the company network.
Ask the specialist to explain the filter chain, authorization boundaries and the handling of failed authentication without relying on vague assurances. Good Spring Security work includes focused tests for allowed and denied requests, documented token and role assumptions, safe defaults and configuration that another professional can maintain.
Bring in a Spring Security freelancer when a team is replacing custom login logic, adding single sign-on, securing APIs or upgrading older configuration patterns. External expertise is especially useful when access rules span several services or when a release depends on an identity-provider integration that the existing team has not handled before.
