Mechanical & Product Design Engineer — Germany

I'm a mechanical and product design engineer working with early-stage startups on the parts of hardware development that decide whether a product actually ships: mechanical CAD, prototyping, and design-for-manufacture.

I've designed axial-flux motor components at Mercedes-Benz, built and validated thermodynamic simulation models at Weiss Technik, and served as the sole mechanical engineer at an air-filtration startup — taking three prototype generations from idea to passed product validation.

I'm comfortable owning a design from a rough sketch through to a tested, working part — running the prototype iterations myself, and treating manufacturability as part of the design brief from day one.

Freelance

Drone Hood Enclosure — DroneShine

Freelance mechanical design

  • Designed and 3D-printed an aerodynamic protective hood for a drone platform — iterated through prototypes until it outperformed the original part
03.2025 — today · Reutlingen

Development Engineer — Product Development

Air-filtration startup, Hochschule Reutlingen

  • Sole mechanical engineer: designed three CO₂ air-filter prototype generations (3 L & 15 L) fully independently in SolidWorks — from mechanical layout to passed product validation
  • 15+ parts and assemblies designed to GD&T, with production-ready drawings that went straight into the line
  • Reduced setup times ~20% through targeted process redesign; built the full BOM/PLM dataset for series transition

Master's Thesis — Thermodynamic Simulation

Weiss Technik GmbH · Environmental simulation systems

  • Extended and validated a CO₂ high-pressure chamber simulation model in MATLAB/Simulink — model deviation vs. real measurement data under 3%
  • 40+ simulation runs analyzing pressure, temperature, and mass-flow distributions in HVAC refrigeration circuits
07.2023 — 01.2024 · Stuttgart

Internship — Drivetrain & E-Drive Pre-Development

Mercedes-Benz AG · Electric drive systems

  • Designed axial-flux motor components in Siemens NX and ran rotor-dynamics simulations — results fed directly into series-production decisions
  • Python automation for simulation workflows cut manual processing time ~30%; DoE optimization across 50+ variants (HEEDS)
  • Calibrated and validated 3D cohesive-zone models in ABAQUS for adhesive-joint analysis against experimental data
