Multi-Agent R&D Pipeline (3 Custom Agents) at Independent Project
Claude Code subagents, MCP, Pydantic V2, pytest, bandit
Designed and shipped 3 specialized agents that hand work down a line: a research agent writes a cited implementation spec, a coding agent builds the modular code and its tests, a review agent ranks findings by severity and applies the fixes. Each handoff is a structured document, so no stage depends on another agent's context window.
Connected the research agent to an academic-research MCP server (Semantic Scholar, ArXiv, Hugging Face Hub, citation snowballing) so every reference traces to a tool result rather than the model. Gated commits behind ruff, mypy, pytest and bandit, required human sign-off before installs and commits, and persisted session state on disk so long runs survive a context reset.

Founder at ProtocolEngine.io
Evidence-led health intelligence platform turning published research into personal health protocols. It scores 430 habits, foods, and supplements against the studies behind them, and moves the score when the evidence moves. Built solo.
- Built the daily ingestion pipeline across PubMed, bioRxiv, and medRxiv: 43,000+ papers from 3,400+ journals processed into 230,000+ typed evidence claims, each one traceable back to the study it came from.
- Designed the six-factor evidence scoring model and the public changelog behind it, so no recommendation ever appears without the papers underneath it. 23,000+ grade changes recorded and explained to date.
- Shipped an entity information model connecting every intervention to its mechanisms, biomarkers, and outcomes: 118 biomarkers with region-specific reference ranges, 77 mechanisms, 32 graded outcomes.
- Built the personalisation layer: blood panel ingestion that reads lab PDFs with a vision model and corrects results for draw time against the user's wake anchor, plus Oura, WHOOP, and Withings integration for daily readiness context.
- Operate eleven specialised review agents over the corpus and codebase, covering paper curation, retrieval quality, health-claim compliance across EU and US regimes, and security.
- Shipped the Evidence Assistant, a RAG assistant that answers from the claim database and cites the underlying papers, plus a B2B practitioner tier, an Expo React Native app, and localisation across 3 languages and 7 markets.
Stack: Next.js 16, TypeScript, Supabase, pgvector, Anthropic Claude, Vercel, DeepInfra.

Agentic Automation and a RAG system
- This project involved extraction of intelligence data to support report writing for a company that provides geopolitical, global, commercial intelligence. The data have been gathered from a number of resources (interview transcripts, online data, internal documents), and then a knowledge base has been build from it. This was the basis of a complex RAG system, that was evaluated against a golden dataset. Agents have been used to find out the contradicting intelligence, the statements supporting each other, and to store back the generated knowledge.
Used: Python, RAG, LangGraph, LangChain, deepeval, MCP

About the technology
What LoRA does
LoRA, short for Low-Rank Adaptation, adapts a pretrained machine learning model without updating all of its parameters. It adds small trainable matrices to selected layers, reducing training demands while preserving the base model. Companies use it to tailor language, vision and multimodal models to focused domains, tasks and writing styles.
Typical applications
LoRA is useful when a company needs a specialized model but wants to keep the original foundation model intact.
- Adapt language models for support, legal, finance or technical content
- Tune image models for products, styles or brand guidelines
- Create task-specific classifiers, extraction systems and assistants
- Maintain separate adapters for customers, regions or use cases
- Combine fine-tuning with retrieval and evaluation workflows
Ecosystem and tooling
Strong LoRA work connects model training with the surrounding machine learning stack. Specialists commonly use PyTorch, Hugging Face Transformers, PEFT and Accelerate, alongside quantization methods such as QLoRA. They also work with tokenizers, experiment tracking, GPU environments, model registries and inference services. In Germany, projects may involve remote collaboration across multilingual product and research teams.
When companies need expertise
Freelance support is valuable when internal teams have a clear adaptation goal but lack capacity for dataset preparation, training design or production rollout.
- A base model performs poorly on domain-specific language
- Full fine-tuning is too costly or difficult to maintain
- Several adapters must serve different products or customers
- Training results are inconsistent across datasets or runs
- A prototype needs a reliable path to monitored inference
Skills that matter
A capable professional understands the trade-offs between adapter rank, target layers, learning rate, batch design and training duration. They can clean and structure datasets, prevent leakage, select meaningful evaluation sets and compare an adapter with the base model. Production work also requires knowledge of quantized inference, GPU memory, versioning, access controls and rollback plans.
Choosing a specialist
Look for evidence of complete adaptation work rather than familiarity with a training library alone. A strong specialist explains why LoRA or QLoRA fits the model, measures quality against a clear baseline and documents data provenance, configuration and limitations. They should also show how adapters are stored, loaded, tested and monitored after deployment. For on-site work in Germany, clarify language, security and collaboration expectations early; remote delivery can work well when the data and compute environment are accessible.
Frequently asked questions
Before you brief your next project: the most common questions about LoRA.
LoRA is used to adapt a pretrained model to a narrower task, domain or style with a relatively small set of trainable parameters. Common projects include domain-specific assistants, structured extraction, image-style adaptation and customer-specific model behavior.
Low-Rank Adaptation changes selected parts of a model through lightweight adapter matrices, while full fine-tuning updates the model’s complete parameter set. LoRA usually makes experimentation, storage and switching between task-specific versions easier, but it may be less suitable when the desired behavior requires broad changes throughout the model.
LoRA adds low-rank adapters to a pretrained model, whereas QLoRA combines that approach with quantization of the base model during training. QLoRA can reduce memory requirements, but it adds quantization choices and quality checks that a specialist must manage carefully.
LoRA work benefits from expertise in PyTorch, Hugging Face Transformers, PEFT, tokenization, dataset engineering and evaluation. Production assignments may also require quantized inference, GPU orchestration, experiment tracking, model serving and monitoring.
A LoRA assignment needs enough practical experience to connect data quality, model choice, adapter configuration and evaluation. The right level depends on whether the work is a controlled experiment, a production integration or a multi-adapter system with strict security and maintenance requirements.
LoRA projects can often be delivered remotely when specialists have secure access to datasets, repositories and GPU infrastructure. On-site collaboration in Germany can help with sensitive data, research alignment or stakeholder workshops, while language and information-security requirements should be agreed in advance.
A strong LoRA professional defines a baseline, uses representative evaluation data and reports both improvements and failure cases. Ask for reproducible training settings, dataset documentation, validation against the original model and a clear plan for adapter versioning and deployment.
LoRA is appropriate when the model must learn durable behavior, terminology, formatting or style from training examples. Retrieval-augmented generation is often better when answers depend on changing documents or traceable source material, and many systems use both approaches together.
The average hourly rate of freelancers in Germany who have used LoRA in their recent projects is 87 €, which corresponds to a daily rate of about 694 € based on an 8-hour working day.
