This year, I plan to get less milestones. But each milestone will be better documented with rationale so that anyone picking up after me will have less technical debt to deal with. Here are some things in my roadmap:
* Summarize academic papers I am reading and attach my highlighted paper in Notion
* Assiduously use git for all code - be it even testing or exploratory analysis. Keep a changelog and wiki/confluence for all features
* Maintain a development log file in the repo which explains rationale, background and supporting information.
* Backup all code and data on at least two providers. I use GCP but it might help to use a cron job to weekly rsync my files to OVH or Hetzner.
* Take up one hobby project and do it well, rather than leaving it at less than optimal.
