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

About the technology
What Prompt Engineering does
Prompt Engineering is the structured design, testing and maintenance of instructions for generative AI models. It helps teams turn broad business goals into dependable outputs for text, code, research, classification and automation. Strong prompts define context, constraints, examples and the expected response format.
Practical applications
- Create customer-support assistants that follow tone and escalation rules
- Extract structured data from contracts, emails and reports
- Generate, summarize and classify content across business processes
- Guide coding, research and internal knowledge workflows
Prompt Engineering supports prototypes as well as production systems. It is often paired with retrieval-augmented generation, tool calling and human review.
Models and tooling
Specialists work with models and APIs from OpenAI, Anthropic, Google and open-source ecosystems. They may use ChatGPT, Claude, Gemini, model gateways, vector databases and evaluation frameworks. Useful skills include JSON schemas, function calling, embeddings, Python, API integration and prompt versioning.
When companies need help
Companies usually bring in freelance expertise when experiments produce inconsistent answers, internal teams lack evaluation methods or a model must fit a sensitive workflow. Cologne businesses can work with local specialists on site or combine remote delivery with focused workshops. Clear English and German communication can matter when prompts serve both local and international users.
Quality signals
A strong professional treats prompts as tested system components, not isolated text snippets. They define success criteria, create representative test cases and compare outputs across models and edge cases. They also document assumptions, protect confidential data and design fallback paths for uncertain responses.
Deliverables and collaboration
Typical deliverables include prompt libraries, reusable templates, evaluation datasets, model comparisons, structured output definitions and integration guidance. Specialists should explain trade-offs between accuracy, latency, cost and maintainability without hiding uncertainty. For ongoing work, they establish review processes so prompts remain useful as models, policies and business requirements change.
Frequently asked questions
Before you brief your next project: the most common questions about Prompt Engineering.
Prompt Engineering is used to guide generative AI models toward useful, consistent and appropriately formatted results. Companies apply it to content generation, document analysis, support assistants, software workflows, research and data extraction.
Prompt Engineering changes the instructions, context and examples given to a model without changing its trained parameters. Fine-tuning adapts a model with additional training data, while retrieval-augmented generation supplies relevant external information at request time.
A capable Prompt Engineering specialist often combines model APIs with Python, structured data formats, evaluation methods and workflow automation. Experience with retrieval-augmented generation, embeddings, vector databases, tool calling and data protection is also valuable.
The right level depends on the use case, model choice and risk of incorrect output. A focused prototype may need a specialist to design prompts and tests, while a production workflow benefits from deeper experience in evaluation, integration, monitoring and failure handling.
Most Prompt Engineering tasks can be delivered remotely because prompt files, test cases and model outputs are easy to review collaboratively. On-site workshops in Cologne can still help when teams need to align on use cases, internal knowledge, language and approval processes.
Good Prompt Engineering is measured with representative test cases rather than a few impressive examples. Ask for clear success criteria, documented edge cases, repeatable evaluations, structured outputs and an explanation of how the specialist handles hallucinations and sensitive information.
Prompt Engineering includes instruction design, but reliable results also depend on context selection, model parameters, output validation and workflow design. Strong specialists connect prompts with retrieval, tools, human review and monitoring where the process requires them.
Before starting Prompt Engineering, clarify the target users, model access, business rules, data boundaries and definition of success. Freelancers should also confirm who reviews outputs, how changes are tested and whether the work includes integration or only prompt design.
