About Herder Elektronische Systemen
Engineering systems that can be understood, tested and trusted.
Herder Elektronische Systemen is an independent engineering practice focused on embedded controls, power electronics, real-time testing, technical recovery and AI-assisted engineering software.
01 / Company focus
Work at the boundary
between disciplines.
The work is centered on systems where software must remain connected to physical evidence: measured signals, hardware behavior, source files, design records and reproducible tests.
Projects are approached as complete engineering systems rather than isolated code or hardware tasks. The practice helps make the interfaces between those parts clear enough to build, test and continue.
02 / Technical index
A capability profile,
not a résumé.
The technical background behind the work spans implementation, physical integration, measurement and documentation.
EmbeddedEmbedded C/C++ and firmware
ControlsMotor control and real-time systems
CommunicationsCAN, UART, SPI and I²C
ModelingMATLAB and Simulink workflows
HardwarePCB design, bring-up and validation
PowerPower-converter prototyping
TestingAutomated test and instrumentation
RecoveryRepository recovery and technical documentation
SoftwareAI-assisted engineering tooling
03 / Engineering principles
Evidence keeps the
system honest.
Keep interfaces, assumptions and constraints attached.
Connect implementation changes to the decision they serve.
Exercise the path between code, hardware and measurement.
State what remains unknown and what would resolve it.
04 / How the practice works
From boundary
to handoff.
State what the system must do and what is in scope.
Review hardware, code, records and dependencies.
Confirm what works, fails or remains unclear.
Change the part that answers the next question.
Leave measurements, limits and next actions visible.
05 / Good-fit engagements
Technical work with
enough substance.
The strongest fit includes:
- Embedded or electromechanical prototypes
- Incomplete or inherited engineering projects
- Firmware and hardware integration
- Test automation and instrumentation
- Design recovery and technical documentation
- Technically demanding early-stage product development
06 / Founder and engineering lead
Jonathan Camfferman-Hernandez
Jonathan Camfferman-Hernandez is a mechanical engineer whose work spans embedded control, electric machines, power electronics, real-time testing, instrumentation and engineering software. His focus is on bringing incomplete or complex technical systems into a state that can be inspected, tested and continued with confidence.
