About Me

After having worked in various positions in China/Hong Kong in the technology and telecommunications space I recently came back to the US with my family to finish my Computer Science degree and go into my original passion as a Software Engineer. An Eagle Scout and an avid fan of Anime and Movies, I am currently looking for a full time, preferably remote/flexible software engineering position in the Los Angeles/Orange County areas.
