About Alex Tse

Tired of waiting for Excel? Don’t want to spend money on expensive data analysis software? Got some big data but don’t know how to deal with it? No problem. I am here to help. I am a data analyst specialising in data automation, big data and data manipulation.My goal is to improve work efficiency, which I have already achieved by using R and Shiny at work. I still remember my first day at Gulf Oil Marine, where all the data was handled by Excel. Analysing the worldwide vessel movement data (with over 14 million records) was impossible using Excel. However, there is no such limit with R.With the use of R and Shiny, the time required to generate a report for LOCUS (Location Operation Call Update Supply) was reduced from several days to just around 3 minutes. Shiny App consists of a web interface for users to upload files and change the parameters or options for calculation. It is easy to use and complex calculations can be completed in several minutes. For simple calculations, it only takes several seconds. Users can perform calculations/analyses anytime, anywhere and on any device as long as they have an internet connection.Besides, updating Excel files using R is just a single click away. I used to spend 1.5-2 working days on Excel to obtain the cost and selling price files. By using R, it now takes less than 1 minute to generate these files. Productivity has been greatly improved.I can also schedule R to run scripts periodically 24/7. Recently, I have developed a system (using R) which will send an email alert with a relevant attachment to users whenever any sanction vessel is detected.*NOTE: R and Shiny are free software.What is R?: https://www.r-project.org/about.htmlExamples of Shiny: https://shiny.rstudio.com/gallery/#demos
