Compact Home Automation PCB Design -- 2

I need a custom-designed PCB for home automation applications, built around the ESP32 DevKit V1.

The PCB will control:
- AC loads via Omron G5LE SPDT relays, optocouplers, and BJT drivers.
- AC dimming (lamp/fan) using MOC3020 opto-driver + BTA16 TRIAC.
- DC loads (like RGB LED strips) using IRF540N MOSFETs.

Key features:
- Integrated AC-DC power supply with bridge rectifier, dual 7805 regulators, and ESP32 3.3V regulator.
- Optical isolation between ESP32 logic and high-voltage circuits.
- External KF301 series connectors for AC input, AC load output, and 12V RGB outputs.
- Status LEDs for debugging and system monitoring.

Requirements:
- Compact and small form factor
- Standard KF301 series connectors
- Improvement related safety
- Songle high Power 30a relay replacement
- 240ac to 5v 2a DC power supply design
- Require editable full source file

Ideal skills and experience:
- Expertise in PCB design
- Experience with high-voltage and low-voltage circuit integration
- Familiarity with ESP32 and home automation systems
- Proficient in using design tools like KiCAD or Altium or EasyEDA

Please provide samples of previous work and an estimated timeline for completion.
