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:
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

About the technology
What Project Lombok does
Project Lombok is a Java library that uses annotations to generate repetitive source code during compilation. It can create getters, setters, constructors, builders, logging fields and value-based methods, keeping domain models and data-transfer classes more concise. The generated behavior remains part of the compiled application rather than a runtime dependency.
Java ecosystem fit
Lombok works across common Java build and application stacks. Strong specialists understand its annotation processor, IDE support, Maven and Gradle configuration, and how it interacts with Spring Boot, JPA, Jackson, testing libraries and Java records. They also know where explicit code is safer than generated code.
- Configure annotation processing in local and continuous builds
- Apply @Value, @Builder, @Data and constructor annotations appropriately
- Review generated methods in persistence and serialization models
- Align Lombok usage with Java language features and team standards
Where companies use it
Companies use Lombok in backend services, REST APIs, event-driven systems and internal Java applications. It is common in models that contain repetitive accessors or constructors, especially across Spring-based services. In Germany, specialists may support teams in finance, manufacturing, logistics and software products, remotely or alongside an on-site group.
When freelance expertise helps
External expertise is useful when a Java codebase is adopting Lombok, upgrading its Java or Spring stack, or suffering from unclear generated behavior. A specialist can establish annotation conventions, configure IDE and build pipelines, migrate repetitive classes and review pull requests. This is also valuable when a team must balance reduced boilerplate with explicit, easily debugged code.
- Introduce Lombok without breaking compilation or IDE workflows
- Refactor verbose Java models with a controlled annotation strategy
- Investigate annotation-processing and generated-code issues
- Document conventions for new services and shared libraries
Quality signals
Strong professionals explain what each annotation generates and how that affects equality, mutability, constructors, serialization and persistence. They test compiled behavior instead of relying only on IDE hints, and they recognize risks around @Data, @EqualsAndHashCode and builder defaults. Good work leaves a consistent codebase that remains understandable to people who do not use Lombok every day.
Alternatives and delivery
Lombok is not a replacement for Java language design. Records, IDE generation, handwritten methods and libraries such as AutoValue may be better for particular models or stricter build environments. The right choice depends on API stability, framework behavior, team preferences and debugging needs. Remote collaboration works well when repositories, build logs, coding standards and review practices are shared clearly; German or English communication can be agreed with the specialist.
Frequently asked questions
Curious about Project Lombok? Here are the answers that come up again and again.
Project Lombok reduces repetitive Java code by generating methods such as accessors, constructors, builders and logging fields from annotations. Companies commonly use it in domain models, DTOs, Spring Boot services and other backend components.
Project Lombok offers broader control over mutable classes, constructors, builders and individual generated methods. Java records provide a built-in, compact model for immutable data carriers, so the better choice depends on framework compatibility, mutability and the intended API.
A strong Project Lombok specialist should understand core Java, annotation processing, Maven or Gradle, IDE configuration and automated testing. Experience with Spring Boot, JPA, Jackson, REST services and code review is also useful because Lombok interacts with these tools and frameworks.
The required depth depends on the task. A focused refactoring may need solid Java and build knowledge, while a large migration also calls for experience with persistence models, serialization, CI pipelines and team-wide coding conventions. Ask for examples of how the specialist handled generated-code risks.
Yes. Project Lombok work is well suited to remote collaboration through source control, pull requests, build logs and shared coding standards. For teams in Germany, agree early on whether communication and documentation will be in German, English or both.
Project Lombok can hide important behavior from readers and create surprises around equality, mutable fields, constructors, builder defaults or framework access. Inconsistent IDE or annotation-processor setup can also produce misleading errors. A careful review policy and explicit annotations for sensitive classes reduce these risks.
Review whether the specialist can explain the generated methods, show the compiled behavior and justify every annotation. High-quality work includes consistent conventions, passing tests, reliable command-line builds and documentation for cases where handwritten Java is preferable.
Project Lombok remains useful when teams want concise classes without adopting records for every model. Its value is strongest in codebases with repetitive constructors, accessors or builders, but professionals should compare each use with records, IDE generation or explicit source code.
The average hourly rate of freelancers in Germany who have used Project Lombok in their recent projects is 92 €, which corresponds to a daily rate of about 736 € based on an 8-hour working day.
