Message from Founder

The critical shortage of IT engineers especially in Japan motivated me to start Tokyo Techies in Japan and Tokyo Tech Lab in Vietnam with the mission of bridging the gap between high demand and low supply of tech talents.

We help enterprises to stay competitive in the global market by providing them with One-stop IT Consulting and Development Support to realize their ideas into world class products and services, then help them to build in-house engineering capacity for the long-term.

With a team of experienced techies from all around the world, we want to make everyone’s lives easier by constantly trying to achieve automation and optimization in everything we build.
