For 2020, I am looking forward to shipping a couple of products for my "stealth mode" startup ;) - using boring stacks I know well PHP/CakePHP, Python/Flask, Java/Dropwizard with the ever reliable Postgres, and maybe Elasticsearch.
As for learning new skills; for the first half of the year I'm playing with Docker more, TUS for file uploads, Apache Pulsar for Pub/Sub, Armeria for building HTTP and RPC services (especially focusing on gRPC services), MQTT for IOT, building USSD apps and WhatsApp bots for different applications as they are increasingly popular around these parts (Africa).
The latter half of the year will focus on mobile development with Android, GraphQL, ML and hopefully get back into Computer Graphics with Processing.
