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

About the technology
PDF in practice
PDF, short for Portable Document Format, is used to create files that keep layout, fonts, and images intact across systems. Companies use it for contracts, invoices, reports, manuals, and forms that must look the same everywhere.
Common work
- Generate PDFs from web apps, office tools, or backend systems
- Build fillable forms and approval documents
- Merge, split, compress, and sign files
- Extract text and data for search or downstream systems
Tools and formats
Strong specialists work with Adobe Acrobat, PDF libraries, and document services that handle rendering, annotation, and conversion. They know when to use PDF/A for archiving, how to preserve accessibility tags, and how to avoid broken fonts or layout shifts.
When specialists help
Companies bring in freelance PDF experts when document output is unreliable, forms fail in production, or a workflow depends on precise file handling. In Dusseldorf, this often matters for teams that serve finance, logistics, legal, and industrial clients with strict document requirements.
What good experts do
Good professionals think beyond export buttons. They check pagination, metadata, security settings, font embedding, digital signatures, and image quality so the file works for real users, printers, and automated systems.
Collaboration and delivery
PDF work can be handled remotely for most tasks, but on-site support can help when print checks, document templates, or internal approval flows need close review. Clear source files, sample outputs, and target devices make collaboration faster and cleaner.
Frequently asked questions
Need clarity? These are the questions we hear most often about PDF.
A strong PDF specialist helps create, edit, convert, and automate documents that must keep their layout intact. That often includes forms, signatures, invoices, manuals, and archived files. The work also covers repair tasks when fonts, images, or page breaks do not behave as expected.
PDF is the right choice when the document must look the same on every device and be ready for sharing, printing, or signing. If the content needs heavy editing or structured data exchange, an editable source file or XML-based format may fit better. Many teams keep both: a working format and a final PDF.
PDF is stronger than Word when you need fixed layout and better control over final output. Compared with HTML, it is better for print-ready documents and offline sharing, while HTML is easier for live content. Image files are simple, but they are poor choices when text search, accessibility, or file size matter.
PDF work often goes with JavaScript, Python, Java, C#, or PHP for document generation and automation. Useful related skills include OCR, digital signatures, accessibility, print preparation, and data extraction. For enterprise work, knowledge of Adobe Acrobat, PDF/A, and document management systems is valuable.
A simple PDF task may only need someone who can clean up templates, fix exports, or wire up a basic library. More complex work needs a specialist who understands rendering engines, font embedding, signatures, and compliance-sensitive output. If the documents are business-critical, it is worth choosing someone who has handled similar file flows before.
Yes, most PDF work can be done remotely because the output is digital and easy to review. On-site collaboration in Dusseldorf is useful when teams need to check print proofs, approval steps, or internal document standards. German language skills can help when the files or stakeholders are local.
Review sample files, ask how they handle fonts, images, accessibility, and signatures, and check whether they can explain why a file fails in production. A reliable PDF professional can describe the tools used, the edge cases tested, and the exact delivery workflow. Good answers are concrete and focused on output quality.
Ask which source files are available, where the PDF will be used, and whether it must support forms, signatures, archiving, or print. For PDF projects, scope is clearer when you define layout rules, security needs, and the target system upfront. That avoids rework and keeps the document workflow stable.
