CodeChef is a not-for-profit educational initiative started by Directi more than a decade ago. We started with a dream of seeing an Indian team winning a gold medal at the ACM ICPC World Finals. In its quest for the same, CodeChef has built a self-driven community of the world's best programmers. Today more than 1.3 million competitive programmers from 180+ countries learn from CodeChef. CodeChef has been hosting monthly programming contests regularly for 10 years now. Its platform has assessed 92 million+ code submissions to date, and over 30000 organizations are being impacted by CodeCheffers worldwide. It also organizes SnackDown - one of the world's largest global programming competition whose last edition drew participation from 140+ countries. Since 2017, CodeChef has started providing India's only industry-ready certification in Data Structures and Algorithms, and 1800+ programmers have been certified under the same.

Have you heard of codeforces.com, atcoder.jp, codechef.com, etc? Source: over 2 years ago
Leetcode is good to learn basic algorithms because problem statements are usually straightforward. Competitive programming has much wider range of problems. Most popular sites for cp are codeforces.com , atcoder.jp, codechef.com . Source: over 2 years ago
Learn Java with hands-on experience. I personally used codingbat.com a lot, but I've heard good things about codechef.com, which appears to even have a competitive option. Source: over 3 years ago
For practicing algorithms, use any of the freely available websites like https://hackerrank.com https://codechef.com https://projecteuler.net A structured set of practice problems are available at https://www.interviewbit.com/courses/programming/ Avoid https://geeksforgeeks.org because it has a ton of material but very poor quality control.

These all have sample problems to solve Hackerrank.com edabit.com codewars.com codechef.com and there are tons more. Best of luck to you. I am at about the same level myself. I really like these sites. Source: over 4 years ago
If you haven't already, check out: https://codecanyon.net/, you can sell scripts. - Source: Hacker News / over 1 year ago
Create and sell reusable code snippets or templates on platforms like CodeCanyon, GitHub Marketplace, and Bitbucket Marketplace. Simplify coding for others. - Source: dev.to / over 2 years ago
Also people are selling whitehat template apps in thousands (through https://codecanyon.net/, for example) and I'm yet to hear Google has removed any of their copies for duplicated content functionality. However I've heard how an app got removed (last autumn) along with its copies after the owner published it as an open-source on GitHub and people started to re-post in in PlayStore. So there is certainly a risk. Source: about 5 years ago
