Meriting experience includes

About you

You are a skilled full stack developer with at least 15 years of experience in web development and have ideally had technical ownership in one or more projects. You are comfortable working independently but also enjoy collaborating with non-technical colleagues. You are pragmatic, solution-oriented, and curious.

You must be able to communicate fluently in English and Thai, both written and spoken.
