Experience
Camera Managing Service
I designed and built a service where the cameras were connected via TCP that was able to send a signal to the cameras to awake them, but also managing their configuration and schedule different behaviors.
I created an internal threads scaling mechanism to allow connections of thousands of devices simultaneously, a custom external scaling mechanism, and a service referencing each camera since sharding or any other cluster method was not possible due to the way cameras were connecting.
I was the one designing and creating each of the components, and my team helped me by reviewing my designs and my code.
