• Served as PoC in i18n & QA project with very complex intents, led the project by coordinating engineers, TPM and teams (30+staff) from different sites in 7 different time zones.
• Implemented end to end technical working flow from scratch; delivered product targets and tasks, mentored among the teams. Reduced the gap dramatically with overall wins in the recall.
• Took a major part in other i18n vertical launches and unblocked launch for P0 bugs and reduced 5% cost.
• By self-driven motivation, I was able to identify issues, report bugs and be part of the solution team even for issues out of my domain e.g google maps, calendar, translate, local time, weather, sports, dictionary, calculator etc.
