Embedded Systems Engineer at Fahlke Control Systems KG in Germany, working with Arm Cortex-M firmware, ESP32 IoT gateways, and industrial control systems. I build cross-platform build and flash toolchains in PowerShell and Nix that auto-generate Makefiles, wrap firmware flashing, and integrate with VSCode tasks — bridging Windows and Linux development seamlessly. B.Sc. in Robotics and Intelligent Systems from Jacobs University Bremen. Certified in Arm Cortex-M architecture and embedded software design. Native Spanish and English speaker, currently learning German.

Not a computer scientist — just an engineer who stitches things together and makes them work. Outside of work, I contribute to the NixOS ecosystem — packaging bleeding-edge software that doesn't exist in nixpkgs and maintaining a performance-tuned multi-host system configuration. Avid system tweaker and optimizer.

nixos — Modular NixOS flake with 200+ custom options across 30+ modules:

Dendritic architecture — every feature is an independent, toggleable module behind myModules.*

Performance-first — CachyOS kernel with Zen 5 microarch compilation, bore scheduler, ananicy-cpp

Multi-host — Desktop (Ryzen 9950X3D + RX 9070 XT) and MacBook Pro 9,2 with kernel specialisations

Automated tooling — nrb build helper, auto-generated docs, config validation scripts
