Last position:
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.

Personal AI Engineering Project — Croky AI at Crocky AI
Product:
- Built a production-ready AI platform for generating brand-aware marketing images and videos from product data, user requirements, and uploaded media.
- Own the platform architecture, technical roadmap, API design, security, deployment workflow, operational reliability, and model-provider strategy.
- Developed the core platform in .NET and built supporting AI and workflow prototypes in Python, applying language-independent API contracts and structured interfaces between services and model providers.
- Implemented reliable background processing with RabbitMQ, persisted workflow state, idempotent handling, retries, failure recovery, logging, secure storage, authorization, and credit accounting.
- Made pragmatic build-versus-buy and model-routing decisions based on reliability, latency, cost, and maintainability rather than novelty.
Agent Orchestration & RAG Systems
- Built and compared agent workflows using Microsoft Agent Framework, LangGraph, and LangChain, including tool use, conditional routing, clarification steps, state management, and hand-offs between agents.
- Implemented reusable .NET components for agents, prompts, tools, model providers, structured responses, and retrieval with pyvector, making it easier to change AI providers without rewriting the core workflow.

Communications Consulting at Storytrend
Most mid-sized companies already have their numbers. What is missing is the translation: a dashboard with forty tiles does not answer a single question that is actually asked in management.
Analysis
- Evaluation of existing data with Python and SQL
- Checking data quality and methodology before making a statement
- The result is an analysis that leads toward a concrete decision
Preparation
- Reports in Power BI and Tableau
- Interactive calculators and visualizations on the web
- Presentations and specialist texts for customers, sales and the public
- Analysis and communication from one source — that

About the technology
What Renewable Energy Covers
Renewable energy uses naturally replenished resources such as sunlight, wind, water, geothermal heat and sustainable biomass to produce power, heat or fuels. Projects range from rooftop photovoltaic systems and wind farms to battery storage, heat pumps, green hydrogen and integrated energy systems. Specialists connect technical design with commercial and operational goals.
Projects and Applications
Companies use renewable energy expertise to plan new assets, improve existing installations and reduce dependence on fossil fuels. Typical work includes:
- Solar photovoltaic and solar thermal system design
- Onshore and offshore wind project development
- Battery storage and microgrid integration
- Green hydrogen and Power-to-X feasibility studies
- Energy audits, decarbonisation plans and technical due diligence
Ecosystem and Tooling
The field combines electrical, mechanical, civil and environmental expertise. Professionals work with PVsyst, HOMER Pro, energy yield models, geographic information systems, SCADA platforms, digital twins and grid simulation tools. They also understand inverters, turbines, batteries, energy management systems, forecasting and power purchase agreements.
When Freelance Expertise Helps
Companies often bring in specialists for a feasibility study, a permitting phase, a tender or a commissioning milestone. External expertise is also useful when an internal team needs capacity for grid connection studies, asset performance reviews or a new energy strategy. In Germany, projects may require close coordination between offices, construction sites, utilities and public stakeholders.
Signs You Need a Specialist
A project usually benefits from focused expertise when its energy yield is uncertain, grid access is unclear or several technologies must work together. Look for support when:
- A site needs resource assessment or feasibility validation
- A connection application requires detailed technical evidence
- Storage must be sized around load, generation and market use
- Construction bids need comparable technical specifications
- An operating asset shows losses, faults or poor availability
What Strong Professionals Deliver
Strong professionals turn complex assumptions into traceable decisions. They validate resource data, state model limits, document design choices and keep safety, maintainability and lifecycle impact in view. They communicate clearly with technical and non-technical stakeholders, coordinate on-site and remote work, and leave behind usable models, specifications, reports and commissioning records.
Frequently asked questions
Not sure where to start with Renewable Energy? These answers cover the essentials.
Renewable energy is used to produce electricity, heating, cooling and low-carbon fuels from resources that naturally replenish. Projects include solar and wind generation, hydropower, geothermal systems, biomass, battery storage and green hydrogen.
Renewable energy generally has low operational emissions and relies on naturally replenished resources, while fossil fuels depend on combustion and nuclear power uses controlled fission. The right mix depends on reliability needs, site conditions, grid capacity, costs, permitting and environmental requirements.
A strong renewable energy specialist may also bring grid connection knowledge, electrical engineering, energy modelling, project finance, permitting, environmental assessment or construction management. Experience with storage, forecasting and energy markets is valuable for integrated projects.
Renewable energy work needs experience that matches the project risk and delivery stage. A specialist for a feasibility study should understand resource data and assumptions, while detailed design, grid integration and commissioning call for proven experience with the relevant asset type and local stakeholders.
Renewable energy planning, modelling, reporting and design can often be handled remotely with structured access to site and operational data. Germany-based projects still benefit from on-site visits for surveys, construction reviews and commissioning, with clear coordination across locations.
A capable renewable energy freelancer can explain assumptions, model limitations, compliance needs and delivery risks in plain language. Review relevant project evidence, the quality of technical documentation, communication habits and experience with the specific technology and project phase.
Renewable energy professionals use tools such as PVsyst, HOMER Pro, GIS software, SCADA systems and grid simulation packages. The exact stack depends on whether the work covers solar, wind, storage, hydrogen, asset operations or broader energy system planning.
Renewable energy projects in Germany increasingly connect generation with storage, flexible demand, heat systems and digital monitoring. Specialists therefore need to assess complete energy systems rather than viewing a solar or wind asset in isolation, while coordinating effectively between remote teams and local site partners.
The average hourly rate of freelancers in Germany who have used Renewable Energy in their recent projects is 118 €, which corresponds to a daily rate of about 945 € based on an 8-hour working day.
