Schematic Circuit Design for Multiple Buck Converters

I'm seeking an expert in circuit design to create a schematic for multiple buck converters. The control should be through an ESP32 GPIO and MOSFETs.

Key Requirements:
- Design for AC input (210V-220V) and DC 48v supplied through USB. Only one Input channel can be active at a time.
- AC to DC converter to convert to DC 48V.
- 5 unique buck-converter channel using LM2596 ot LM2576 to stepdown the voltage to 3.3v, 5v, 9v,12v, 24v
- Each of these unique channel only turn on the Switching regulator once it receives signal from ESP32 GPIO.
- Dupont pin (female) connector pin should be available to connect esp32 Dev Kit board (32 pin).
- Array of Dupont Femail pin should be available for above 5 channel linked by jumper cable
- 1 AC output channel should be available that should also be control via esp32 gpio and TRIAC

Note - Must do simulation for each output channel to indicate the component used are the correct sizing.

Ideal Skills:
- Proficient in Schematic Circuit Design
- Experienced with Buck Converters
- Familiar with ESP32 and MOSFETs
- Able to conduct thorough simulations
- Understands LED load requirements

The design should be able to handle an input voltage of 48V and power multiple LED lights through the buck converters. The ideal freelancer will have experience in creating such designs, with the ability to conduct simulations to ensure efficiency and reliability. Please include any relevant past work in your proposal.
