Back to original languageAbout Coumba
I am a hardware engineer with over 7 years of experience in electronic system design. I can assist you in the design and market launch of your products.
I have worked on an electronic board production line, providing support to the production and quality teams, and managed the design office in the development of new products and technological monitoring. I have also worked with 2 startups in designing their IoT solutions.
I have designed PCBs from 2 to 6 layers, CE certified, using Eagle, Cadence-Orcad, or Altium, with microcontroller technologies (Atmel, Microchip, etc.), system-on-chip types like Espressif, and system-on-modules with Arduino, Raspberry Pi, and BeagleBone.
With CNERGY SAS as a freelancer, I can assist you with your electronic board design projects, from defining specifications to mass production, covering all development phases:
• Needs analysis
• Feasibility study, realization, and validation of a PoC
• Product development (Prototyping, small and medium series)
• Project management
• Industrialization
• Product certification and qualification
