Interested in contributing to GNU Taler

Hello

I have prevously contributed to other NLnet and NGI projects and now am
interested in contributing to Taler via NGI TALER. I'm mostly
interested in the "software engineering aimed at adapting to new usage
areas or improving software quality" part of that project. I am
currently setting up a webshop (still in planning stage) and want to
accept payments using GNU Taler. I previously only used other parts of
GNUnet, including GNS, re:claimID and Messenger-GTK and tried
https://demo.taler.net/ on a regular basis. Currently I am reading
