Programming / Data Wrangling Bounty Jobs?

I'm not ready nor could I handle the responsibilities of a full time developer job, but I was wondering if there's a site that assigns a bounty to complete programming or data related tasks so I could start earning some income while becoming a better developer? Smaller tasks would be preferred, it'd be great if I could just make an extra $50 a day working from home. Ideally this would be something like github, but with bounties posted for bugfixes or feature implementations.
