Back to original languageAbout Jascha
Hello dear SME or start-up :)
I develop connected products from electronics to firmware to the production web app - for companies that want to turn their vision into a stable product.
Many hardware and IoT projects fail not because of the idea, but because of the implementation:
Sensors, actuators, firmware, communication, backend, and web don't mesh cleanly or remain at the prototype level.
I support companies in developing and advancing functional products – technically clean and realistically implementable.
Typical tasks:
- New development of prototypes and MVPs (HW & SW)
- Transition from prototype to near-production system
- Stabilization and improvement of existing solutions
- Development of an end-to-end IoT architecture
- Technical responsibility & consulting for the overall system
