Hi,
I have been developing Alexa Custom Skills since last 4 month into my company.
I have experience of creating 5-6 custom alexa skills, which are being used in our company for internal showcases & usage.
Skill which i have developed includes, simple input/output commands, integration with DynamoDB, integration with Socket communication for communication with different IoT devices, Mobile Apps, Smart TVs.
I have experience of using latest Alexa Skill Node JS SDK released by Amazon Team.
I also have experience on AVS (Amazon Voice Services).
As skills i have developed is not published on Store as it is for internal usage only, but if you are interested we can setup an meeting to demonstrate it.
