(1) Business process modeling tool where processes are data and not graphs. I am doing it according to the USM method. USM is kind of "open source" service management method, although it works on different level than other frameworks and standards, and is compatible with all of them.

This makes it possible to create a kind of requirement "programming language" where the requirements can be evaluated. With this language it becomes possible to create cross-references from various compliance standards/frameworks, like ISO27K, to USM, and automatically evaluate the compliance.

(2) Dance event calendar in Finland, running in production for over a year. 1-2M page views/month. Django app, but I am now implementing a copy of the unauthenticated user views to S3 bucket and delivering it through Cloudflare.

(3) Django app to handle all the data related to custody trial. Emails, SMS, notes, official records, voice memos, etc. can be attached to a timeline, and tagge and searchable. It has command line interface for adding data, in addition to UI, so I can quickly add notes and attach files.
