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.

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
What Spring Security does
Spring Security is the security framework for applications built in the Spring ecosystem. It handles authentication, authorization, session protection, password storage and defenses against common web attacks. Companies use it to control access across browser applications, REST APIs, microservices and internal business systems.
Core security patterns
Strong implementations begin with a clear identity and access model. Experts configure filter chains, security contexts, password encoders, CSRF protection, CORS rules and method-level access controls. They also separate authentication from business permissions so security rules remain understandable as the application grows.
Identity and APIs
Spring Security connects Spring applications with external identity services and enterprise directories. Common work includes OAuth 2.0 resource servers, OpenID Connect login, JWT validation and session-based authentication. Professionals also secure service-to-service calls, API gateways and token flows without placing sensitive credentials in application code.
Ecosystem and tooling
Spring Security is closely linked to Spring Boot, Spring MVC, Spring WebFlux and Spring Authorization Server. Effective specialists understand the surrounding Java ecosystem, HTTP, TLS, cookies, tokens and identity provider configuration. They use integration tests, security test utilities, dependency checks and logs to verify both permitted and rejected requests.
- Configure authentication and authorization flows
- Protect REST and reactive APIs
- Integrate OAuth 2.0 and OpenID Connect providers
- Review permissions, sessions and token handling
When companies need specialists
Freelance expertise is valuable during a migration from custom authentication, a move to centralized identity or a redesign of microservice access. It also helps when audit findings reveal weak authorization, inconsistent endpoint rules or unsafe token handling. In Munich, specialists may collaborate on-site with product and security teams or work remotely with clear documentation and secure access.
What quality looks like
A capable professional can explain every trust boundary, authentication decision and authorization rule in plain language. They test failure paths, expiry, revoked credentials, insufficient permissions and cross-origin behavior rather than checking only successful logins. The best work leaves maintainable configuration, focused tests and guidance for the team that will operate the system after delivery.
Frequently asked questions
Need clarity? These are the questions we hear most often about Spring Security.
Spring Security protects Spring applications by managing authentication, authorization and security-related request handling. It supports browser sessions, REST APIs, OAuth 2.0, OpenID Connect, JWT-based access and method-level permissions.
Spring Security offers deep integration with Spring Boot, Spring MVC and Spring WebFlux, plus broad support for modern identity standards. Apache Shiro can be simpler in some standalone applications, while custom security code usually creates more maintenance and testing risk.
Spring Security work benefits from knowledge of Spring Boot, Java, HTTP, TLS, cookies, JWT, OAuth 2.0 and OpenID Connect. Experience with identity providers, API gateways, databases, Docker and automated security testing is also useful.
The right level depends on the risk and scope of the system. Spring Security work for a public API, federated identity setup or complex permission model calls for a professional who can design trust boundaries, test failure paths and review the full authentication flow.
Spring Security projects are often suitable for remote collaboration because configuration, tests and security reviews can be shared through controlled repositories and documentation. On-site sessions in Munich can still help when teams must align on identity ownership, threat models or operational procedures.
Ask the professional to explain the authentication flow, authorization rules and handling of expired or revoked credentials. With Spring Security, quality also means tested denial paths, safe secret management, clear configuration and protections that remain consistent across every endpoint.
Spring Security supports reactive applications built with Spring WebFlux as well as traditional servlet-based applications. A suitable specialist should understand reactive security contexts, non-blocking request handling and the differences between reactive and servlet filter chains.
A strong Spring Security professional should be able to document security decisions clearly and discuss risks with both technical and business stakeholders. English is common in international teams in Munich, while German may be useful for internal policies, workshops or regulated environments.
