QA/QC support for accelerator facility assembly at FAIR GmbH
Background Construction of the Super-FRS, a research facility over 200 meters long for the separation of atomic nuclei. Quality tasks had largely been delegated to work package owners, work package leaders, assembly leads and production planning; the required quality expertise and coordinated implementation needed further development.
Responsibility Responsible for Quality Control from incoming goods through NCR and problem-solving management to quality handover for Commissioning. Further developed the quality skills of operational leads; coordinated closely with GSI quality colleagues for development and Supply Chain Management.
Actions Defined quality milestones, inspection requirements and inspection procedures with the responsible functions and supported their implementation. Managed deviations at component and assembly interfaces that only became apparent during installation through NCR and problem-solving management; coordinated and followed up on technical clarification, corrective actions and verifiable quality records.
Result Strengthened quality expertise and independent quality practices within operational functions; established clear inspection requirements and NCR procedures. Ensured quality-assured assembly within the project scope and helped shape the quality culture. Assignment expected to end early in October/November 2026 as part of project-wide budget consolidation.

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.

European Strategy Atlas – Independent Analytics & Decision-Support Project at Independent Project
Designed and built an end-to-end interactive decision-support application using public European data across 27 EU countries and multiple strategic dimensions. Developed a structured analytical methodology for comparing countries, identifying patterns and trade-offs, and exploring strategic choices rather than presenting static dashboards. Translated complex multidimensional data into guided interactive exploration and learning workflows for non-specialist users. Built the application end-to-end using Python and Streamlit, with AI-assisted development and Git-based version control. Developed the project independently from problem framing and data analysis through methodology, UX logic, implementation and deployment.
Tools: Python, Streamlit, Git, AI-assisted development

About the technology
Systematic Empirical Modeling
Design of Experiments, frequently abbreviated as DoE, provides a structured framework for manipulating independent process variables to observe shifts in target responses. Instead of traditional one-factor-at-a-time testing, this approach maps factor interactions, nonlinear trends, and experimental error using minimal trial runs.
Core Frameworks and Matrices
Practitioners apply specialized mathematical designs matched to project constraints and system complexity:
- Full and fractional factorial designs for factor screening
- Response surface methodology including central composite and Box-Behnken designs
- Taguchi orthogonal arrays for robust parameter design
- Definitive screening designs to avoid confounding main effects with quadratic terms
- Mixture designs for formulation and chemical development
Analytical Tooling Ecosystem
Specialists execute test matrices and evaluate empirical data using dedicated statistical software suites. Standard workflows rely on platforms like JMP, Minitab, Design-Expert, and Statgraphics. Advanced workflows integrate computational scripts in Python using Statsmodels and SciPy, or R packages like FrF2, rsm, and DoE.base for automated model fitting and contour analysis.
Industrial Applications in Germany
- Automotive powertrain calibration and battery cell manufacturing
- Semiconductor yield enhancement and photolithography optimization
- Chemical synthesis, polymer compounding, and process engineering
- Biopharmaceutical drug formulation and bioreactor parameter tuning
- Additive manufacturing parameter development for aerospace alloys
When External Expertise Is Required
Organizations engage external specialists when engineering teams hit performance plateaus, process variance drives up scrap rates, or rapid product qualification is mandatory. External specialists eliminate guesswork, establish clear signal-to-noise separation, and prevent costly, redundant trial cycles during scale-up phases.
Hallmarks of Seasoned Specialists
Top practitioners distinguish between mathematical ideals and real-world shop floor constraints. They master blocking strategies to isolate environmental drift, identify severe collinearity, and interpret residual diagnostics. Beyond statistical software proficiency, they bridge data models with underlying physics and chemical dynamics.
Frequently asked questions
What clients ask us most about Design of Experiments — answered in short.
Design of Experiments replaces arbitrary trial-and-error testing with structured mathematical matrices. It uncovers complex multi-factor interactions, isolates root causes of process variance, and establishes optimal operational envelopes with the smallest possible number of physical or simulation runs.
Traditional one-factor-at-a-time testing fails because it cannot detect interaction effects between variables and requires vastly more test runs. In contrast, DoE changes multiple parameters simultaneously in a balanced manner, providing greater statistical power, higher precision, and clear predictive equations.
Specialists working with experimental design frequently utilize software packages like JMP, Minitab, and Design-Expert. For programmatic modeling and reproducible research pipelines, specialists also rely on R and scientific Python libraries to script analysis and visualize response surfaces.
In Germany, Design of Experiments is central to automotive engineering, chemical production, medical technology, and semiconductor manufacturing. Freelance specialists frequently assist German industrial firms in regions like Baden-Württemberg, Bavaria, and North Rhine-Westphalia with plant trials and yield optimization.
Yes, matrix creation, simulation modeling, and data evaluation are handled remotely with ease. However, when DoE involves pilot plants, physical machinery setups, or cleanrooms in Germany, a hybrid model allows specialists to observe test execution and verify sensor measurements on site.
An experienced practitioner of Design of Experiments uses blocking, randomization, and replication to neutralize background noise. When external factors cannot be held constant, specialists apply Taguchi methods or analysis of covariance to build processes that remain robust despite ambient fluctuations.
A strong background combines applied statistics with engineering, chemistry, or physics. Look for professionals who explain aliasing structures, resolution levels, and residual diagnostics clearly, rather than relying solely on default outputs from automated statistical packages.
After initial screening matrices isolate critical factors, specialists apply response surface methodology, a core subset of DoE. This technique models quadratic curvature to pinpoint the exact parameter settings that maximize yield, reduce cycle times, or hit specific quality targets.
