  8. Website is too slow, app not able to download

    You are doing great job but just for silly reasons of design of web application one may lose interest of taking course.

    1) bottom arrows to go to next page is not working
    2) filters are absent to filter out the beginner and intermidiate courses
    3) surfing speed can be improved
    4) left side catelog or content page design need to improved

  16. jobs.cognitiveclass.ai job board

    I know there are lots of job boards out there like glassdoor.com, indeed.com, ziprecruiter.com et. al.

    But I think a jobs.cognitiveclass.ai board would be a great place for employers and employees to get matched over the skills taught in various courses at Cognitive Class.

  17. Use public key encryption to digitally sign certificates for strong validation of authenticity

    I think CognitiveClass.ai is great, even better than edX which I began using in 2013.

    The first edX certificates were issued as digitally-signed (using public key encryption technology) PDF files. Because they were digitally signed, anyone was able to validate the certificate's authenticity in a rigorous manner, making the certificate a more trustworthy credential for employers. I think the potential was there (using this cryptographic signature) for MOOC certificates to become even more rigorously reliable (practically untamperable) than even official college transcripts.

    Unfortunately, edX abandoned this feature in their certificates after 2-3 years. I've never understood why they abandoned this…
