I recently transitioned from a front-end position to a back-end position, so I'm currently learning Java as well as a bunch of architectural and devopsy topics for work. On the side, I want to get better at shipping, so I have a goal to ship an actual product this year. What I'm working on at the moment is written in Node (which I already knew fairly well) on Lambda + SNS + DynamoDB + ElasticSearch (which I did not know).
