CTO  RapaQ

Manager 50%  Coding 50%  

In the past year in RapaQ, I led a team of 12 specialists, including UI designers, front-end and back-end engineers.
Within three months, we built and launched a B2B2C e-commerce platform. Three more platforms were developed and completed within one year. 

Consisting of 4 platforms (Qshare, Qgoods, Qmaker, point), our website is aimed at providing one-stop services to designers, makers, consumers, fundraisers and investors.
As the CTO of our company, my responsibilities include:
Develop a technical strategy based on our company’s business objectives.
Provide market expertise for sales organizations and participate in partner meetings.

Utilized social media and online marketing strategies to build a strong online presence on our platforms.

Conduct research and identify customer needs to develop a competitive positioning for our company. （Our website is differentiated from other similar platforms in that it combines social networking, the community market, e-commerce, and new media into one all-around platform. 

We cooperate with several factories for mass production and we offer fundraising resources as well. 

This allows makers and designers to focus on designing and crafting without worrying about sources of funds.
Review codes and make sure the best practices are followed by the team.
