About this Gig

Welcome here


Wireless systems dont fail loudlythey fail in performance.


Most projects struggle with weak signals, unstable firmware, or poor PCB layout. I engineer wireless ESP32/STM32 embedded systems that deliver strong connectivity, efficient performance, and production-ready reliability.


My Services:

  • Wireless PCB design
  • ESP32 embedded system
  • STM32 embedded system
  • Firmware development
  • Hardware schematic design
  • IoT device prototyping
  • WiFi integration
  • BLE (Bluetooth) setup
  • RF layout optimization
  • Signal integrity design
  • Power management design
  • Low power optimization
  • Sensor integration
  • Multilayer PCB routing
  • Circuit simulation
  • Real-time firmware
  • Communication protocols (UART/SPI/I2C)
  • Cloud/IoT integration
  • Debugging & troubleshooting
  • Code optimization
  • DFM/DFA checks
  • Gerber file generation
  • BOM preparation
  • Testing support
  • Performance optimization

Why my service

  • Strong hardware
  • Firmware integration
  • Reliable wireless
  • Production ready
  • Scalable design
