Summary
👤
SeniorJohannes Bauer is a Lead Creative Technologist and Software Systems Engineer with 14 years of experience building interactive, often experimental systems that bridge software, hardware and media. He combines full-stack and cloud architecture work (including Azure tenant and resource management) with embedded firmware, custom electronics and real-time integrations for installations, VR/AR and kinetic systems. Trained as an IT systems integrator and later as an electronics technician, he brings rare operational insight from production of control systems for specialty vehicles alongside hands-on development. He is an active open-source contributor with low-level work in projects like OpenSSL and practical full‑stack improvements to browser-based electronics simulators, demonstrating both crypto-level rigor and robust remote-control interfaces. Johannes also runs a data recovery service for private clients, reflecting a pragmatic, customer-focused approach to technical problem solving. Based in Niederkassel, Germany, he thrives on projects that require inventing new forms of interaction rather than following conventional software-only paths.

Electronic Circuit Simulator in the Browser
Role in this project:Full-stack Developer
Full-stack DeveloperContributions:15 commits, 2 PRs, 3 comments in 17 days
Contributions summary:Johannes implemented a WebSocket-based interface to control and interact with the electronic circuit simulator. The contributions involved adding commands to read/write the simulation timestep, reload the iframe, and import/export circuits. They also introduced commands for shutting down the simulator and waiting for its availability, demonstrating a focus on robust remote control functionality. Furthermore, the user exposed SVG export functionality and refactored event handling for improved reliability.
