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 data visualization does
Data visualization turns raw data into charts, dashboards and interactive reports that reveal patterns, changes and exceptions. It helps teams explore information, explain findings and make decisions without relying on dense spreadsheets. Strong work connects every visual to a clear business question and a trustworthy source.
Common deliverables
- Executive dashboards for revenue, operations, finance and customer activity
- Interactive reports with filters, drill-downs and role-based views
- Exploratory charts for trends, outliers, cohorts and geographic data
- Data stories and presentation visuals for stakeholders
- Reusable visualization components for web applications
The right format depends on the audience, the refresh cycle and the decisions the report must support. Accessibility, responsive layouts and clear labeling matter as much as visual appeal.
Tools and ecosystem
Professionals may work with Tableau, Microsoft Power BI, Looker or Qlik for business intelligence reporting. Custom browser-based work often uses D3.js, JavaScript, React and established charting libraries. Productive projects also require SQL, data modeling, APIs, spreadsheets and cloud data warehouses.
When companies need specialists
- Existing reports are slow, inconsistent or difficult to maintain
- Teams need a governed dashboard for shared performance views
- A product requires embedded analytics or custom interactive charts
- Data sources must be combined into a reliable reporting model
Companies in Germany often bring in freelance expertise for a focused dashboard rollout, a reporting redesign or a temporary gap in analytics capacity. Remote collaboration works well when data access, ownership and review routines are defined early; on-site work can help with workshops and stakeholder alignment.
What strong professionals bring
A strong specialist combines visual judgment with analytical and technical discipline. They clarify definitions, inspect data quality, choose an appropriate chart and document the logic behind each metric. They can explain trade-offs to business teams while keeping queries, models and dashboards maintainable.
Look for a portfolio that shows more than attractive screens. Ask how the professional handled ambiguous requirements, performance constraints, permissions, accessibility and feedback from real users. A short review of the underlying data model and interaction design can reveal the quality of the work.
How projects succeed
Start with decisions and audiences rather than a list of charts. Agree on metric definitions, source ownership, refresh expectations and access rules before building the first dashboard. Then test prototypes with the people who will use them and remove visuals that do not support an action or insight.
Freelance specialists can improve an existing setup, establish a reporting standard or deliver a complete visualization workflow. Clear acceptance criteria should cover accuracy, usability, performance, documentation and handover. That gives internal teams a dependable foundation for future reports.
Frequently asked questions
Before you brief your next project: the most common questions about Data Visualization.
Data visualization is used to make patterns, comparisons and changes easier to understand. Companies use it for operational dashboards, financial reporting, product analytics, forecasting and presentations. The best result helps a defined audience answer a practical question or take action.
Data visualization offers interactive exploration, shared definitions and a clearer view of trends than a static spreadsheet usually provides. Spreadsheets remain useful for ad hoc analysis and small, controlled datasets. A specialist can decide whether a dashboard, spreadsheet or combination is the better fit.
Data visualization projects often use Tableau or Power BI when teams need governed self-service reporting and established connectors. D3.js is better suited to highly custom, web-based interactions and embedded product experiences. The choice depends on data sources, users, security, maintenance and the level of design control required.
Data visualization work benefits from SQL, data modeling, dashboard UX, statistics and knowledge of APIs or cloud warehouses. Experience with Tableau, Power BI, Looker or D3.js can be important, but tool knowledge alone is not enough. The specialist should also understand data quality, accessibility and stakeholder communication.
Data visualization work does not require the same depth for every assignment. A simple report may need focused dashboard and SQL skills, while a governed analytics system requires experience with modeling, permissions, performance and adoption. Assess the complexity of the data and decisions before choosing the level of expertise.
Data visualization projects can usually be delivered remotely when access, security and review processes are clear. Workshops with German stakeholders may benefit from on-site sessions, while most design, modeling and dashboard work can happen online. Agree on collaboration language, documentation and data-handling rules at the start.
Data visualization quality is visible in accurate metrics, readable layouts, useful interactions and reliable performance. Ask the specialist to explain the source data, metric definitions, design choices and testing approach behind a portfolio example. A practical review task can show how they handle ambiguity and feedback.
Data visualization projects start more smoothly when the company defines its audience, decisions, data sources, refresh needs and access roles. It should also clarify whether the deliverable is a dashboard, an embedded component, a reporting model or a visual story. These details help the specialist estimate scope and recommend the right tools.
The average hourly rate of freelancers in Germany who have used Data Visualization in their recent projects is 86 €, which corresponds to a daily rate of about 692 € based on an 8-hour working day.
