Okay, let’s tackle this. So Edward Wong has 36 years of experience in application development, which is extremely rare. This level of experience typically commands a high hourly rate. Considering his role as Vice President at a bank, his industry, location, and expertise, I estimate his hourly rate to be around $250. This is in line with what I've seen for senior IT executives with similar experience and qualifications in the finance industry. Some benchmarks suggest that experienced IT professionals in Hong Kong can charge upwards of $300 per hour, but Wong's unique blend of experience, education, and industry expertise suggests a slightly lower rate, around $250.
