Building complete systems withtechnical precision and economic thinking.

I am Raphael Erwig, an Industrial Engineering student specializing in Electrical Engineering. I develop technical solutions from the first concept to a functional prototype while considering performance, feasibility, cost and practical value.

About me

Engineering has fascinated me since childhood. Today, I combine technical development with an interest in business, numbers and economically sound decisions.

My fascination for engineering began when I built and modified nitro-powered RC cars together with my father. Over time, this curiosity developed into the ambition to create increasingly complex hardware and software projects independently.

I study Industrial Engineering with a specialization in Electrical Engineering because successful technical development requires more than engineering knowledge alone. Technical performance, costs, efficiency, feasibility and business value all influence whether an idea becomes a successful solution.

I am currently in my fourth semester. I am particularly interested in hardware development, embedded systems, computer vision, additive manufacturing and the interaction between technology and economics.

How I work

My projects combine technical depth, independent learning, initiative and economic evaluation.

Complete Systems

I enjoy developing complete solutions instead of focusing on only one component—from the first concept to a functional prototype.

Rapid Learning

When a project requires new skills, I independently learn the necessary tools and apply them directly to a real technical challenge.

Personal Initiative

I invest my own time and resources into ambitious engineering projects beyond university coursework.

Economic Thinking

I evaluate technical decisions not only by performance, but also by cost, efficiency, feasibility and practical value.

Selected projects

Independent projects that combine engineering, experimentation, software, hardware and system-level problem solving.
