Hi! Thank you for taking your time to read my codes written in Trip!
Due to the contract I have signed with Trip(携程), I can't share the codes I've written in the company!
However, some statistics and information can be outlined as follows:
- I have written over thousands(beyond 2k) lines of codes.
- Most of the codes consist of Sql, Hive, Spark(80%); The rest consist of shell and python.
- My daily routine during the intern includes: constructing data tables that contain data needed to help model the algorithms; Meeting with Production Group to help them finalize their decisions or brainstorm some ideas; Writing python codes to build up models to solve problems.
- Projects I have participated include the following:
1): helped to improve the accuracy for predicting prices of airline tickets in the 7/30/60days. And I constructed/maintained the 7,30 sametake database tables, wrote python codes for 30 days/half year/one year ROI evaluation.
2): Responsible for risk management project(confidential), I have trained a machine learning model and improve its precision to 90% compared with its last update version for five years ago.
3): Price lock project(confidential)
