Talanoa▲341Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years.

You can access these across your devices, and share them with other ente users, end-to-end encrypted. You can also use our electron app[6] to maintain a local copy of your backed up files. We've built a fault-tolerant data replication layer that replicates your data to two different storage providers in the EU. We will be providing additional replicas as an…
