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.

Marc S.
Last position:
Fullstack Developer at PLANT-MY-TREE
PLANT-MY-TREE®-per-order
The application enables Shopify merchants to automatically place tree-planting orders for every incoming order. By integrating ecological contributions directly into the purchase process, the manual effort for tracking and billing reforestation initiatives is eliminated. The system increases transparency for end customers through real-time visualizations of the ecological impact directly in the storefront. The architecture is based on a modular monolith with Spring Boot in the backend and an integrated React app inside the Shopify admin area. The solution uses webhooks to capture order data in an event-driven way and integrates the weclapp ERP system for automated monthly invoicing. An app proxy mechanism provides dynamic statistics such as CO2 compensation and planted trees without any performance loss for the merchant shop.
Tasks:
- Design of the modular software architecture based on Spring Modulith to ensure high maintainability
- Development of the event-driven business logic for evaluating Shopify orders via webhooks
- Implementation of automated invoicing by connecting the weclapp REST API
- Building the frontend using React Router and Shopify App Bridge for native integration
- Design of the database model and implementation of the persistence layer with JPA/Hibernate and Prisma
- Integration of internationalization processes for global use in the frontend and email communication
- Automation of deployment processes using Docker and GitLab CI/CD

About the technology
What Lombok does
Project Lombok is a Java library that generates repetitive code during compilation through annotations. It can provide getters, setters, constructors, builders, logging fields and value-based methods without requiring teams to maintain each method manually. The result is shorter source code, but the generated behavior still needs careful review.
Java ecosystem
Lombok works inside common Java build and development workflows. Strong specialists understand annotation processing, Maven and Gradle configuration, Java language features, Spring and Spring Boot conventions, JPA entities, serialization and testing. They also know how IDE plugins and compiler settings affect the experience of each team member.
Typical deliverables
Companies use Project Lombok in services, APIs and business applications where Java models contain substantial repetitive structure. Typical work includes:
- Introducing annotations into an existing Java codebase without changing public behavior
- Configuring Lombok for Maven, Gradle, CI pipelines and supported IDEs
- Replacing hand-written accessors, constructors and builders safely
- Reviewing generated methods in records, DTOs, entities and immutable value objects
When specialists help
Freelance expertise is useful during Java modernization, codebase cleanup, team onboarding or a migration from manually maintained boilerplate. Companies may also need an independent review when Lombok annotations have spread inconsistently, build failures appear in CI, or generated methods create surprises in persistence, serialization or inheritance. In Germany, remote collaboration is common, while some teams prefer on-site workshops and German-language communication.
Quality signals
A strong professional treats Lombok as a design choice rather than a shortcut applied everywhere. They explain what the compiler generates, check annotation combinations, protect API and data-model contracts, and document project conventions. They also assess whether plain Java, records or a smaller annotation set would make a class easier to understand.
Maintainable adoption
Good implementation balances concise code with discoverability for people who are new to the repository. Specialists establish rules for annotations such as @Data, @Value, @Builder, @Getter and @Slf4j, then validate the result with tests and static analysis. They watch for issues involving mutable entities, equals and hashCode, constructor visibility, inheritance and IDE or compiler differences. Clear standards make Lombok an aid to maintenance instead of hidden complexity.
Frequently asked questions
Curious about Project Lombok? Here are the answers that come up again and again.
Project Lombok is used to reduce repetitive Java code by generating members such as accessors, constructors, builders and logging fields from annotations. Teams often apply it to DTOs, value objects, service classes and other models, while reviewing generated behavior as part of code quality checks.
Lombok offers a broad set of annotations and can support existing mutable classes, builders and framework-specific patterns. Java records provide a language-level option for compact data carriers, so a specialist should compare mutability, inheritance, serialization and framework requirements before choosing between them.
A Project Lombok specialist should also understand core Java, annotation processing, Maven or Gradle, IDE configuration and automated testing. Experience with Spring Boot, JPA, serialization and CI pipelines is valuable because Lombok-generated members often affect those parts of an application.
The right level depends on the scope. Lombok cleanup in a small service may need focused Java expertise, while a large migration calls for someone who can inspect inheritance, persistence mappings, generated methods, build tooling and team conventions across the whole codebase.
Yes, Project Lombok work is well suited to remote collaboration because configuration, code review and testing can be handled in shared repositories and build pipelines. For teams in Germany, agree early on working language, review practices, overlap hours and whether architecture workshops require on-site attendance.
Ask a Lombok freelancer to explain what selected annotations generate and where they would avoid using them. Review examples involving entities, builders, inheritance and equality, and look for evidence of disciplined testing, documentation and compatibility checks across local and CI builds.
Project Lombok does not add a runtime service, but its generated code can affect behavior when annotations are chosen carelessly. Common concerns include equality on entities, unwanted setters, constructor visibility, serialization, builder defaults and differences between IDE support and compiler configuration.
Lombok is not automatically the best choice for every team. It can improve readability in repetitive classes, but teams may prefer explicit Java or records when generated members would be difficult to discover, when tooling support is restricted, or when long-term maintainability favors visible code.
The average hourly rate of freelancers in Germany who have used Project Lombok in their recent projects is 91 €, which corresponds to a daily rate of about 727 € based on an 8-hour working day.
