I have been fortunate to have a career path which has taken me to Taiwan, United States, Hong Kong and China. This trajectory has given me first-hand experience in the evolution of the main aspects of connected devices or “Internet of Things” (IoT) as it is referred to nowadays.


After working on devices in many different places, I would say Shenzhen is still the best place for making devices within budget and on schedule. However, it does require communication skills with the suppliers in order to ensure the quality and schedule. Being native Chinese, it is definitely easier for me to work with them because of our common language and culture.


It's no longer the dot com and enterprise service bus days when we needed to put up a lot of effort and resources to achieve hardware and network scalability on the server side. Cloud solutions like Amazon Web Services (AWS) and Google have made server-side development much easier.

On the other hand, since there are many different cloud providers and each offer a large number of services, it is not straight forward to piece together the right services into your own cloud solutions.


With so many open source solutions built on Mapreduce, NoSQL and RDD, data analytics are no longer limited to relational database and programming languages. However, some of the big data solutions used for devices are kind of an overkill for these devices. I look forward to any form of collaboration to apply IoT to improve people's lives in different parts of the world.
