I am the co-author of some Stata packages. They can all be downloaded through ssc. Please reach out if you have any comments or suggestions!

• number_exporting (with Olena Bogdan, Adrien Matray, and Chenzi Xu)
  Format a given numeric value produced in Stata based on user specifications. It outputs the formatted number into a .tex file that can then be called directly into the paper or document you are working on.
  
• winsor4 (with Adrien Matray)
  Trim or winsorize a variable based on outliers defined by either percentiles or interquartile range.
  
• evstudydd (with Adrien Matray)
  Estimate event studies in D-i-D settings using the reghdfe or ppmlhdfe packages.
  evstudydd produces all the point estimates and standard errors, together with a time indicator, and saves them in a .dta file, which can then be merged or appended with other files to produce more flexible graphs.
