Since childhood I love writing books, doing research, making databases and statistics. I started using computers in 1997, my dad taught me to use Word, but around 2003 I started using Excel more than Word. Analyzing data, making tables and charts about everything encountered in my life! For example, in racing games I measure the speed of each car and write the numbers in an Excel spreadsheet then make a chart.
Early works were pure hobbies, made from personal interest, with no plans to commercialize them.
Hong Kong Housing Database was also made from personal interest of analyzing public housing estates, few months later, an insurance company asked me if I can expand it to private housing estates. It became my FIRST large project made for a customer.
Car Database were also started as hobby for my personal use, but had an unexpected turnout into business after 2012 when I realized that many companies in automotive industry are paying big $$ to get a complete, accurate, and frequently updated database. I went through extensive transformation to make my hobby databases suitable for professional use.
Starting from 2015 I learned web scraping. Scraping usually means running a software to visit a list of given pages, extract specific data and put it in a database automatically. This allow me to create very large databases with little effort, spending ~30 min to write codes and leave scraping software to run in background for few hours or days.
Between 2015 to 2017 I created over 50 databases via web scraping, some from personal interest to sell to multiple people (India, Middle East and Australia car databases, mobile phones databases, etc) and others for single customers who requested them (web scraping services).
Keeping all databases regularly updated takes is a huge workload. Scraping more websites, if they take too much time, will create additional workload and will delay everyone’s updates. As 2018 I decided to STOP updating databases having less than 5 sales per year so I can focus on the ~20 best-selling databases that produce 80% of my income.
So… unless you come with a GREAT IDEA of database that can be sold to multiple customers, I have the right to NOT do your web scraping project if it takes more than ~2 hours of manual work and more than ~50 hours of running scraper in background.
Some projects (example Database of HDB Resale Flat Prices) involve copying the data from a source website and pasting in Excel, then few visual adjustments to make it beautiful, which takes just few hours to create a 20 MB Excel database.
Other projects (example Database of HDB blocks) involve compiling data from various sources and manual data entry in Excel, taking hundreds hours of work!
All my projects are made primarily for visualization in Excel, but some (especially the Car Database) are often used by professionals who are converting the Excel spreadsheet to CSV and MySQL and use in web design and mobile app development.
