Jens R.
Last position:
Platform Architect & Senior Developer at Direct client, industrial measurement technology, medium-sized company
- Technical leadership across hardware, firmware, and software teams; scope: hardware/firmware team (4 people) and leadership group (5 people)
- Consolidated and documented a product family that had grown over more than 15 years and aligned it with CRA compliance — from the bare-metal I/O module to the cloud interface.
- Provided the most important customer product with the essential requirements and architecture documentation within two months — for a firmware landscape that had grown over more than 15 years. It now supports the customer’s modernization strategy.
- Established a monthly reporting line to the supervisory board and executive board within three months: nine meetings since 12/2025. The report itself is versioned and built from the CI pipeline; it is based on automatically collected activity and release data instead of assessments.
- Built a container-based CI/CD infrastructure from scratch: cross-compilation, host tests, and documentation builds in one continuous pipeline.
- Introduced declarative QA gates for DevOps and development artifacts — from the start using lefthook instead of pre-commit, executed in a dedicated container image.

About the technology
What Gemini covers
Google Gemini is Google’s model family for text, image, and more. Companies use it for assistants, content workflows, search support, classification, and data extraction. It also appears in projects that need fast prototyping around Google Workspace or cloud services.
Common work
- Prompt design for product and internal assistants
- API integration with Gemini and related Google tooling
- Multimodal use cases with text, images, and documents
- Content generation, summarization, and enrichment flows
- Evaluation and prompt tuning for reliability
Ecosystem fit
Strong professionals know the Gemini API, Google AI Studio, and how it connects with Vertex AI. They understand model selection, safety settings, structured output, and retrieval setups. Good work also includes logging, testing, and careful handoff into existing systems.
When companies bring help
Teams usually look for outside expertise when a pilot needs to become production-ready or when internal staff lacks model experience. That is common in Cologne as well, especially for companies working across marketing, customer support, analytics, or software delivery. Remote collaboration works well when goals and input data are clear.
What strong specialists do
They do more than write prompts. They shape input and output formats, handle edge cases, and keep the setup usable for real teams. They also compare Gemini with other LLM options when cost, latency, safety, or Google integration matter.
Quality signals
A good specialist can explain trade-offs in plain language and show how the system behaves on real examples. Look for clean prompts, repeatable tests, clear documentation, and practical knowledge of Bard-to-Gemini migration questions. They should help you ship something stable, not just impressive in a demo.
Frequently asked questions
Need clarity? These are the questions we hear most often about Google Gemini.
Google Gemini is used for assistants, document analysis, content support, and workflow automation. Companies also use it for multimodal tasks such as reading images, summarizing files, and extracting structured information from unstructured input.
Google Gemini is the current name for Google’s consumer and model family branding, while Bard was the older public name many people still search for. In hiring terms, that usually means the same skill area: prompts, API use, and product integration around Google’s model stack.
Google Gemini is often chosen when Google ecosystem integration matters, especially with Vertex AI or Workspace-related workflows. ChatGPT and Claude are common alternatives, so a good specialist should explain where Gemini is the better fit and where another model may be stronger.
A strong Google Gemini specialist usually knows prompt design, API integration, evaluation, and basic data handling. For production work, skills in Python, JavaScript, cloud services, and retrieval-based setups are often important too.
You do not need a finished project to bring in Google Gemini expertise. Many companies hire early for use-case scoping, proof of concept work, or to avoid building a brittle prompt flow that needs rework later.
Google Gemini work is often remote-friendly because most tasks happen in prompts, APIs, and testing environments. On-site sessions in Cologne can still help when teams need fast alignment on data access, compliance concerns, or workshop-style discovery.
A good Google Gemini freelancer shows clear test cases, explains limitations, and can compare outputs across different inputs. Look for practical thinking about safety, structured responses, and how the setup will be maintained after launch.
A Google Gemini project often ends with prompt templates, API-connected workflows, evaluation notes, and documentation for the team. Depending on the scope, you may also get a prototype assistant, content pipeline, or retrieval setup ready for handoff.
