Okay, let’s tackle this. So Karthik has a solid set of skills in programming languages like Java, C, and C++. He also has experience in Android and iOS development, which are in demand. However, his skills in databases and Linux administration are not as highly sought after. Location is Seattle, which is a hub for tech companies. According to national averages, junior developers with his skillset can charge around $75-$100 per hour. Considering his skills and location, I estimate his hourly rate to be around $75.
