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

About the technology
Prompt basics
Prompt engineering is the craft of asking large language models for the right output, in the right format, with the right constraints. It covers prompt design, prompt writing, and the practical testing needed to make results stable and useful.
What experts deliver
- Chat prompts for support, sales, and research workflows
- System prompts and instruction sets for assistants
- Few-shot examples, templates, and reusable prompt libraries
- Output formats for JSON, summaries, classifications, and actions
- Guardrails for tone, scope, and response quality
When teams bring help in
Companies bring in specialists when a model sounds useful but still gives vague, inconsistent, or unsafe output. They are useful for first builds, prompt cleanup, regression testing, and turning one-off prompt ideas into a repeatable process.
Ecosystem and tools
Strong professionals work across ChatGPT, Claude, Gemini, Microsoft Copilot, and API-based stacks built on OpenAI or Anthropic models. They often pair prompts with retrieval, evaluation sets, playground testing, and lightweight automation so the output fits the product and the team.
What strong specialists do
Strong prompt engineering specialists do more than write clever text. They define the task, test edge cases, compare model behavior, and refine prompts until the output is predictable enough for real work.
Dusseldorf collaboration
In Dusseldorf, prompt work often supports industrial, retail, media, and B2B teams that need English and German output to feel natural. Many projects fit remote work well, but local workshops can help when stakeholders need fast alignment on tone, policy, or workflow design.
Frequently asked questions
Before you brief your next project: the most common questions about Prompt Engineering.
A strong prompt engineering specialist designs instructions that make a language model return the right answer, in the right style, with the right structure. That includes prompt drafting, testing variations, and tightening edge cases when output drifts. The best specialists also think about the surrounding workflow, not just the wording.
They are closely related, but prompt engineering is the broader discipline. Prompt design and prompt writing usually describe the practical act of crafting prompts, while prompt engineering also includes testing, iteration, and quality control. In many teams, the terms are used interchangeably.
Prompt engineering is most useful for chatbots, assistants, content workflows, search over internal knowledge, classification tasks, and structured output generation. It also matters when a team wants the same model to behave consistently across different users or languages. If the output must be reliable, the prompt needs a specialist touch.
A good prompt engineering freelancer usually understands product thinking, evaluation methods, basic data handling, and how APIs connect to the model. Experience with retrieval-augmented generation, guardrails, and prompt testing tools is often valuable too. For Dusseldorf teams, clear German and English writing can be a real advantage.
Prompt engineering changes the instructions; fine-tuning changes the model with training data. Most teams start with prompts because they are faster to test and easier to change. Fine-tuning becomes relevant when prompts alone cannot deliver enough consistency, style control, or domain fit.
For a simple prototype, a specialist who knows prompt engineering and model behavior may be enough. For customer-facing assistants or internal tools with strict output rules, you want someone who has already shipped and tested similar work. The more important the workflow, the more you should value evidence of real iteration.
Yes, prompt engineering is often a strong fit for remote work because most of the task happens in text, test cases, and shared examples. That said, local sessions in Dusseldorf can help when teams need to align on brand voice, compliance, or stakeholder expectations. Many projects use a mix of both.
Look for clear examples of how prompt engineering decisions were tested and improved over time. Good specialists can explain why a prompt works, show how they handle bad outputs, and describe what they changed when the model failed. If they only share clever wording without evidence, that is a warning sign.
