Infrared Light Control PCB Design

I need a proficient PCB designer who can create a unique design for an infrared light control system. This system will be housed on a compact, single-layered PCB, requiring detailed and thoughtful design to optimize the efficiency.
- PCB Layer: Single-layer PCB
- PCB Size: Flexibility is key here as the size is yet to be determined. A guided proposal on the size based on the functionalities to be embedded will be advantageous.
- Special Characteristics: The PCB must be designed to handle a microcontroller that controls an infrared light. Hence, expertise in microcontroller integration to PCB is required.

Skills and Experience:
- Proficient with single-layer PCB designs
- Deep understanding of microcontroller integration into PCBs
- Experience with embedded systems, specifically relating to lighting systems, is a plus
- Adequate knowledge about power management for efficient operations.

Please provide a portfolio or examples of similar projects you've worked on. This project requires quick, efficient work so timing is crucial.
