circuit designed for old arcade cabinet - 6 speed gearbox that uses an Up Switch, Down Switch Left Photo Interrupter and right photo interupter to select which gears - connected to a USB zero delay arcade encoder

I am looking for a skilled circuit designer to create a circuit for my old arcade cabinet. The circuit will be responsible for selecting gears in a 6-speed gearbox. The circuit will utilize an Up Switch, Down Switch, Left Photo Interrupter, and Right Photo Interrupter to determine the selected gear.i.e a combination of Left interrupt sensor and up switch = 1st gear = button 1 on USB encoder, Additionally, the circuit will be connected to a USB zero delay arcade encoder (as per photo). and then be connected to a windows PC.

Ideal Skills and Experience:
- Strong background in circuit design
- Experience with gearbox control systems
- Familiarity with arcade cabinet components
- Proficiency in working with photo interrupters

Attached is a video of a test photo interrupter attached to the USB Zero Delay Encoder.

Note When left Photo interrupter and up switch is activating Button 1, button 3 should not be activated (up switch only) other combinations.

Please note that there are no specific component or brand preferences for the circuit design. The project can be completed within a timeframe of more than 2 weeks to ensure thorough testing and optimization.
