I’m currently working on a payment gateway for Elixir. So far I have have been working on a PayPal integration and have the basics up and running.

I`m learning elixir by doing work for small customers that need a quick fix for something.
-
Having successfully deployed 6 small crud apps I am now taking one of them, a logistics application and improving it to a fully fleshed out system.

and I am making a food/health application on my spare time to track allergens and other abnormalities that could have an impact on your health (mainly made for lupus patients, but can be used for many others as well)

I’ve been building various web crawlers we use for my day job in Elixir over the past 8-12 months - but nothing real big until recently. Last week I launched my first fully distributed production system (1 ‘coordinator’ node and 4 worker nodes) and it was quite a positive experience.
Took me a little over two months from scratch and a little under 6000 lines of Elixir (excluding tests, comments, etc) with just me working on it. I know it is not a real big codebase, but I’m proud of the fact I was able to get it out the door by myself and in hindsight it would have been extremely difficult to accomplish what I have in another language. I’ve had it running in some form since about a week into the project, so I was able to stand up some MVP tests early on. The plan to go distributed happened at the end, so it was a ‘trial under fire’ situation by turning a lot of reading and small tests with distributing elixir/erlang into real life.
The performance since launch has been awesome as well - by far our best performing system and most stable, even in the short amount of time it has been running for clients. My current capacity on four very modest worker nodes will allow me to retire around 8-10 legacy servers from these tasks.
I’ve used Phoenix before, but this project is just a traditional OTP app. There is a small web UI that shows node status and work being done in realtime - but I just used Plug for handling routing and cowboy for a simple websocket setup. If I have to do a deeper admin interface down the road - I’ll just add a Phoenix project into the umbrella.
Releases and deployment are done via Distillery and edeliver.
If anyone is in this space (crawling/scraping) and has questions - feel free to DM me and I’ll do my best to answer them.

Thanks for sharing your experience, @adammokan. I’m wondering what were your biggest challenges in building your system, and what background processing queue are you using? For example, I’m working on a small project that involves scraping, and so far I’m using exq + Floki.
