About

From a complex problem to a working solution

Robert Kotsch

I'm Robert Kotsch. I design and develop digital tools and interactive experiences, combining software, applied AI and 3D visualization. I enjoy working through a complex problem, testing an approach and turning it into something people can use.

My work includes a browser-based braiding-machine simulation, a pricing engine, reusable HTML5 development tools and local AI applications. I connect the underlying rules with the interface and implementation, from the initial concept through testing and refinement.

Since 2009, I've developed digital learning for technical, regulatory and safety-related subjects. My instructional-design experience helps me structure complex information and make interfaces understandable. Explaining decisions and helping people use what I build are part of that work; my focus is the design and development of the solution itself.

Capabilities

Turn recurring tasks into workflows

I build production tools and reusable components that connect documented rules, software and delivery. The WBT Pricing Engine and HTML5 Asset Playbook show this approach in practice.

  • JavaScript & TypeScript
  • React & Vite
  • Three.js & WebGL
  • Python
  • HTML5/CSS

Connect knowledge, rules and workflows

I connect documented business rules, software and AI-assisted workflows, and build local AI tools for tasks such as transcription and language practice.

  • LLM Integration
  • Local AI
  • Skills
  • RAG/LLM Wiki
  • Workflow Automation

Make technical processes visible

I create product visualizations, animations and browser-based 3D experiences that reveal how mechanisms and systems work.

  • Houdini
  • Blender
  • Substance Painter
  • Unity
  • Adobe Creative Suite

Build understanding through interaction

I turn complex technical subjects into interactive learning assets and simulations. Instructional design informs the structure, interface and feedback so people can explore how a system works.

  • Articulate Storyline
  • Articulate Rise
  • Knowledgeworker Create
  • SCORM
  • xAPI

Have something to build?

I'm interested in roles and projects where I can design and build applications, automation tools and interactive experiences. If you need someone who takes a problem from concept through implementation, let's talk.
