  This is a new challenging step which has a high impact on my career experience in the following areas:
  - Testing and troubleshooting procedures of PCBs.
  - Mastering PCB design using Altium Designer, I really mean mastering.
  - High-Power electronics concepts of circuit design and PCB Layout.
  - Defined system topology and voltage/current ratings for 1 kW–10 kW systems.
  - Collaborated with mechanical and thermal teams on busbar layout and cooling interface design.
  - Designed LCL filters and grounding structures to improve EMC/EMI performance.
  
  Let's talk in more details,
  During this period, I'm part of a team that working on designing, testing, and troubleshooting:
  1. 10KW Wireless Power Transfer System (Inductive Power Transfer).
  2. 10KW BLDC Motor Driver.
  
  Which really gave me a deep understanding of:
  - High-Voltage & High-Current Inverters using SiC MOSFETs, IGBTs.
  - Gate drivers to drive such a high-power semiconductor.
  - Power Switching Regulators.
  - Voltage and Current measurement circuits & their signal processing.
