About this Gig

I am an Embedded Systems & IoT Engineer designing Mixed Signal Audio PCBs using ESP32 for reliable embedded hardware systems integrating audio codecs, SD card storage, and clock synchronization for real world applications.


I provide full PCB design including schematic, PCB layout, and professional PCB positioning for optimal signal integrity. Focus areas include analog or digital separation, low noise routing, impedance control, and clean power design for high quality audio performance.


What I offer:

  • ESP32 based audio PCB design
  • Audio codec integration & SD card systems
  • Clock synchronization architecture
  • Mixed signal PCB layout (analog + digital separation)
  • Schematic design, PCB layout, BOM, and Gerber files
  • PCB positioning for signal integrity and low noise


Why choose me:

I engineer real world working systems, not just circuits. Every PCB is optimized for performance, stability, and manufacturability, with focus on clean signal flow, low noise, and reliable embedded integration for professional results.
