Last position:

Senior Software Engineer — AI Evaluation & Benchmarks at Diversido

  • Provided technical leadership for a 4-engineer team delivering 3 major client platforms in 12 months with microservices architecture and scalability solutions — 100% of scoped majors shipped ahead of schedule vs. planned milestones (baseline: prior releases often slipped 1–2 sprints).
  • Ran AI model evaluation and model outputs evaluation on LLM/AI vendor APIs: safety, completeness, instruction adherence, and groundedness review before go-live; cut escaped bad outputs in AI-integrated release checklists from recurring UAT findings to near-zero on final promote.
  • Drove API development and performance optimization for payment, exchange, and AI services; fail-closed error handling and payload validation reduced integration rework cycles by ~35% vs. the first AI integration pass.
  • Applied software testing, testing frameworks, code quality assurance, and code refactoring with continuous integration gates; first-pass PR acceptance improved across the team and production hotfixes on AI adapters dropped noticeably after review standards landed.
  • Owned DevOps practices: Docker, GitHub Actions, Jenkins-compatible pipelines, and version control workflows — cut deployment time ~50% vs. pre-automation baseline and stabilized releases across 3 client environments.
  • Implemented verifier/oracle-style pass-fail checks in container sandboxes (Harbor/Terminal-Bench aligned); wrote technical documentation so failures cleared in one review cycle.
  • Led cross-functional collaboration with product and client stakeholders; translated AI evaluation scores and risk findings into plain-language briefs for non-technical partners, unblocking go/no-go decisions without extra engineering meetings.
  • Used agile methodologies for sprint planning and backlog ownership; mentored engineers so mid-level contributors owned AI adapter modules independently by mid-engagement.

About the technology

Vector search foundation

Weaviate is an open-source vector database for storing objects alongside vector embeddings and querying them by meaning. It supports semantic search, similarity matching and retrieval workflows that go beyond exact keywords. Teams use it to give applications context-aware access to documents, products, media and structured data.

AI application building blocks

Weaviate commonly sits behind question-answering tools, recommendation features and content discovery interfaces. Its modules and integrations connect data to embedding models, rerankers and large language models, making it suitable for retrieval-augmented generation and other AI application patterns. Specialists also shape schemas, collections and metadata filters around the product requirements.

Ecosystem and operations

A strong implementation may involve Weaviate Cloud or self-hosted Weaviate, Python or TypeScript clients, REST and GraphQL APIs, Docker, Kubernetes and cloud storage. Experts handle imports, batch processing, indexing, authentication, backups and observability. They also connect model providers and data pipelines without losing control of access or provenance.

Where companies use it

  • Search internal knowledge bases by intent rather than wording
  • Retrieve grounded context for conversational AI and RAG applications
  • Recommend products, articles, jobs or media from user and item meaning
  • Match support cases, documents or profiles with related records
  • Combine semantic retrieval with keyword filters and business rules

When freelance expertise helps

Companies bring in freelance Weaviate specialists when a prototype must become a reliable service, an existing search stack needs a semantic layer, or model and data choices are still unsettled. They can assess whether vector search fits the use case, design a migration path and establish evaluation methods. In Germany, remote delivery is common, while on-site workshops can help align product, data and infrastructure teams.

What good specialists deliver

The best professionals connect retrieval quality with practical system constraints. They define useful metadata, select and test embedding models, tune hybrid queries and measure results with representative queries. They explain trade-offs clearly, protect sensitive data and document deployment, monitoring and handover so the system remains maintainable after the engagement.

Frequently asked questions

Everything clients usually want to know about Weaviate, in one place.

Weaviate is used to store and search data through vector embeddings, so applications can find content by meaning. Companies use it for semantic search, recommendations, document retrieval, image or media discovery and retrieval-augmented generation.

Weaviate is designed around vector and semantic retrieval, while Elasticsearch is often chosen for mature keyword search, analytics and broad text-search features. A relational database remains the source of truth for many transactional workloads. The right choice depends on query needs, data shape, operational constraints and whether hybrid search is required.

A capable Weaviate freelancer usually understands embeddings, vector search, metadata filtering and retrieval evaluation. Useful adjacent skills include Python or TypeScript, REST or GraphQL APIs, data pipelines, cloud infrastructure and large language model integration. Experience with Docker or Kubernetes helps when the service is self-hosted.

The required depth depends on the risk and scope of the work. A proof of concept may need someone who can model data, create embeddings and validate retrieval quality, while production work calls for experience with ingestion, security, scaling, monitoring and failure recovery. Ask for examples involving data and query patterns similar to yours.

Yes. Weaviate work is often delivered remotely through repository access, technical documentation and scheduled workshops. On-site collaboration in Germany can be useful for discovery, data governance or cross-functional design, while clear communication in English or German should be agreed at the start.

Weaviate Cloud reduces infrastructure work by providing a managed service, while self-hosting offers more control over deployment, networking and operational policies. The choice depends on compliance needs, cloud strategy, team capacity and the level of control required over upgrades and scaling. A specialist should compare the total operating effort, not only the hosting setup.

Evaluate Weaviate work with representative queries and clearly defined relevance criteria. A strong professional can show how embeddings, filters, hybrid search and reranking affect results, then explain latency, cost, security and monitoring trade-offs. Reproducible tests and useful documentation matter as much as a convincing demo.

Yes. Weaviate can retrieve relevant passages or objects that an application supplies as context to a language model. A freelancer should also address chunking, metadata, source attribution, prompt construction, access controls and evaluation, because a vector database alone does not guarantee accurate or grounded answers.

The average hourly rate of freelancers in Germany who have used Weaviate in their recent projects is 102 €, which corresponds to a daily rate of about 816 € based on an 8-hour working day.

Of the freelancers in Germany who have used Weaviate in their recent projects, 83% hold at least a Bachelor's degree, 58% hold at least a Master's degree, and 17% hold a doctorate.

On average, freelancers in Germany who have used Weaviate in their recent projects have 17 years of professional experience, with a single engagement typically lasting around 2 years.

The most common languages among freelancers in Germany who have used Weaviate in their recent projects are German (100%), English (100%), and French (23%).

The most common industries among freelancers in Germany who have used Weaviate in their recent projects are Information Technology (100%), Professional Services (62%), and Healthcare (54%).

The most common business areas among freelancers in Germany who have used Weaviate in their recent projects are Information Technology (100%), Product Development (100%), and Project Management (69%).
