Hello @ Modisch Fabrications

Hi, I'm Robin Modisch. I am a software developer and engineer based in Germany. I specialize in high-skill challenges that require bridging the physical and digital domains. From designing custom PCBs and writing firmware, to deploying robust backends and fabricating the final physical enclosure. If you have a concrete problem that spans multiple disciplines, you are in the right place.

Expertise

CAD, 3D Printing & Lasercutting

Extensive experience in Computer-Aided Design for 3D Printing, Lasercutting, and rapid prototyping.

Electronics & IoT

Specialized in embedded systems, schematic and PCB design with KiCAD, and connecting hardware to the web.

Software Engineering

Developing robust software architectures, including Dockerized backends, Python APIs, and custom web interfaces for hardware control.

Robotics & Automation

Hands-on experience in controlling a variety of sensors and actuators, translating code into physical movement.

Usability & Mixed Reality

Developing interactive, user-focused experiences across various platforms, particularly for VR and AR environments.

Applied AI

Integrating AI into development workflows for code generation and creating custom intelligent tools, focusing on engineering over hype.

Epoxy & Silicone

Fusing art with functionality to create custom molds, functional parts, and unique sculptures.

Wood & Metalworking

Tinkering with forging, welding, and cutting to build practical physical items, from heavy-duty tree stands to custom lamp shades.

Projects

CutSolver

Free and open-source webservice to minimize waste by optimizing cut placements. Set your available stock length, estimate cut widths, fill in the quantity and size of your desired pieces and let this tool handle the calculations.


Technically speaking this is an NP-hard optimization problem. This website uses a perfect bruteforce solver for smaller quantities with on-demand fallback to a faster first-fit-decreasing solver if it would exceed 12! permutations.

Frontend:

Vue + Bootstrap

Backend:

Python + FastAPI

DevOps:

Docker + Caddy on OCI

Mixed Reality Robot Remote

Immersive gesture-based robot control based on mixed reality; validated with real test subjects in a closed study.


This project was part of my master's thesis in collaboration with Siemens. The aim was to develop a new type of robot controller that enables flexible access to production systems without physical access. It's a mixture of robotics, usability design, networking and mixed reality that fit perfectly into my skillset.

Hardware:

Universal Robot's UR5e; Microsoft Hololens 2

Middleware:

Python + URControl

Frontend:

Unity + MRTK

3D-printed Tools & Utilities

Autonomous Rover

ROBIT is a teaching and learning platform meant to teach pupils the basics of robotic systems. The goal is to retrieve an imaginary treasure from the bottom of the dark sea, where only sonar can be used to detect anything. The drone has to find, collect and deliver autonomously without external control.


The algorithm is simple: Drive in straight lines, turning at boundaries detectable by IR. Rotate frequently, collect distance readings, drive towards the closest treasure. Collect it via magnet, raise it and drive out of the sea. The main challenge is to do all that in realtime on a microcontroller with cheap peripherals.

Hardware:

Arduino Nano, HC-SR04 Ultrasonic sensor, KY-024 Hall Sensor, MPU6050 Gyro + Accelerometer, IR Sensor, L9110S Motor Driver, 2x Geared Motor, Servo, 10x WS2812B RGB LED

Ribbed Vase

3D-printed flower vase with mesmerizing patterns. Designed to be printed as one continuous loop without any seams. Published free for personal use, instant hit with users from all around the world printing their own versions.

Crystal Coasters

Digital design, physical process: A 3D-printed positive was cast in silicone to create a mold. The wood was then routed to size with a 3D-printed template and cut into inlays by hand. These inlays were then placed and cast in epoxy resin within the silicone mold. The resulting piece was trued up with a belt sander first and then polished up to 800 grid.

Tools:

Router, Oscillating Saw, Belt Sander, Orbital Sander

Material:

Acacia Wood, Epoxy Resin, Mica Pigments

Indestructable Tree Stand (v1)

Rugged by design and fabricated from heavy-duty materials for outdoor use; created as a prototype. Bulky enough to be a traffic stopper for upcoming generations with roughly 23 kg.


Born out of the necessity to present a christmas tree securely - Most commercially available alternatives are too weak & unstable for wind and weather.


Trivia: This was actually planned and created with CutSolver.

Tools:

Angle Grinder, Flux-Cored Welder, Step Drill

Material:

40x40x5mm Steel Square Tube; Stainless Screws

Finish:

Sandblasting + Hammerite

About me

I am a Software Developer, Engineer, and Maker based in Germany. With over 11 years of experience across commercial development and physical fabrication, my goal is simple: I want to be able to build absolutely anything.

My academic journey began with a Bachelor's in Electronics and culminated in a Master's in Computer Science from FAU Erlangen-Nürnberg. Professionally, I've worked on prototypes at Siemens and currently lead developments as a CTO at NeoBird.

In my downtime, this platform is my chaotic sandbox. It is a space for creative engineering where I step away from commercial constraints to solve tangible, real-world problems. I am driven by mechanics and logic, and I actively seek out challenges that require me to apply multiple disciplines to bring a complex concept to life.

Frequently Asked Questions

What kind of projects do you take on?

I actively seek out high-skill tasks with a high degree of freedom, inspired by concrete, real-world problems. Whether it requires bridging the physical and digital (like designing a custom PCB and writing the firmware) or purely physical fabrication like casting custom epoxy molds, the goal is always to build a complete, functional system.

Are there tasks you actively avoid?

I am an engineer, not a magician. I leave the voodoo of high-frequency RF engineering, deep ML mathematics, and bare-metal kernel development to others. I also avoid trivial tech support, extreme micro-optimization in a single narrow silo, and corporate overhead. When I am off the clock, I have zero interest in team management or business development. I just want to build and solve hard technical problems.
