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
WildFly at a glance
WildFly is a Jakarta EE application server used to run Java business systems, web applications, and service layers. It is known for solid runtime management, fast startup, and flexible deployment models. Many teams still search for it as JBoss, JBoss AS, or JBoss EAP.
Typical work
- Deploy and update enterprise Java applications
- Configure data sources, messaging, and security realms
- Set up standalone or domain mode
- Triage startup errors, classpath issues, and server logs
It fits back-end systems that need clear administration and a stable server runtime.
Ecosystem and tooling
Strong WildFly specialists work with Jakarta EE, JTA, JMS, CDI, and JAX-RS. They also know the tools around the server, such as Maven, Gradle, Docker, and automation scripts for repeatable releases. In Germany, this often matters for internal business systems where Java teams and infrastructure teams work together.
When companies bring help
Teams usually bring in freelance expertise when a server needs migration, performance tuning, or a clean setup for a new release. The same is true when old JBoss-based services must move to modern WildFly versions without breaking application behavior. Remote collaboration works well for most tasks, while on-site support helps during rollout windows or sensitive cutovers.
What strong professionals do
Good WildFly professionals read logs quickly, understand deployment descriptors, and know where configuration belongs. They can explain clustering, transactions, security, and connection pooling in plain terms. They also keep changes small and documented so operations teams can support the system later.
Signs you need a specialist
- Deployments fail after a platform upgrade
- Applications are slow under load
- Security, LDAP, or TLS setup is unclear
- The team inherits an older JBoss environment
If you see these signs, a WildFly specialist can stabilize the server and reduce risk during change.
Frequently asked questions
The facts hiring teams ask for most often when it comes to WildFly.
WildFly is used to run enterprise Java applications that need a managed server, not just a simple servlet container. Companies use it for internal business apps, service APIs, batch integration points, and systems that depend on Jakarta EE features like transactions, security, and messaging.
WildFly is the current community application server from the JBoss line, and many people still call it JBoss or JBoss AS out of habit. In practice, that often means the same family of server skills, especially around deployment, configuration, and Java EE or Jakarta EE runtime management.
WildFly is broader than Tomcat because it includes a full Jakarta EE application server stack. Tomcat is lighter and fits simpler web apps, while WildFly is better when you need built-in support for transactions, messaging, security realms, clustering, and managed enterprise deployment.
A strong WildFly specialist usually knows Jakarta EE, Maven, SQL, Linux, and Docker. For many projects, they also need working knowledge of ActiveMQ or Artemis, TLS, LDAP, reverse proxies, and logging tools so they can solve problems across the whole runtime path.
A small deployment or configuration task may need only a focused specialist, but upgrades, clustering, or migrations from older JBoss setups need deeper server experience. WildFly work becomes harder when custom modules, old application descriptors, or legacy security settings are involved.
Most WildFly tasks can be done remotely because the work centers on configuration, deployment, and log analysis. On-site support in Germany is useful when a release is sensitive, the environment is tightly controlled, or the team wants direct coordination during a production change.
Look for clear examples of server setup, upgrade work, and problem solving under real constraints. A good WildFly specialist can explain domain mode, data sources, clustering, and security without hand-waving, and they leave the environment in a state your team can maintain.
The most common issues are version mismatches, broken deployment descriptors, memory pressure, and unclear separation between application code and server configuration. WildFly projects also fail when teams treat the runtime like a black box, so a good specialist documents what was changed and why.
The average hourly rate of freelancers in Germany who have used WildFly in their recent projects is 96 €, which corresponds to a daily rate of about 767 € based on an 8-hour working day.
Of the freelancers in Germany who have used WildFly in their recent projects, 89% hold at least a Bachelor's degree, 50% hold at least a Master's degree, and 6% hold a doctorate.
On average, freelancers in Germany who have used WildFly in their recent projects have 24 years of professional experience, with a single engagement typically lasting around 2 years.
The most common languages among freelancers in Germany who have used WildFly in their recent projects are German (100%), English (94%), and French (19%).
The most common industries among freelancers in Germany who have used WildFly in their recent projects are Information Technology (98%), Banking and Finance (65%), and Government and Administration (54%).
