Developer Advocate
I support you by explaining the technology.
Asmati Tatsumi(Asmati Tatsumi)/Software Engineer / Developer Advocate
For asopi tech's products and OSS, I explain how they work, where they fit, and what to watch out for. I post plain-language technical explainers on our social accounts.
If something technical is unclear, please just ask.

Role

You want to know how it works
I explain what the product or the OSS does and how it behaves.
You want to know if it fits your environment
I go through the operating conditions, what you need to run it, and which uses it suits or does not.
You want to compare the options
I explain how it differs from the common approaches and what to weigh when choosing.
You want the caveats before adopting it
I tell you the current limits, what is not built yet, and the settings to be careful with.
You want to contribute to the OSS
I point you to the repository, the issues, the development setup, and a first step.

Together
Posting together with Takamine Akari
We plan and post the things only the two of us can do.
- Introductory explainers, with Akari asking from the user's side and me answering from the implementation side.
- What the work looks like, and off-shots. Scenes from the office, events, picking up gear, and whatever we end up talking about
- Short exchanges on X and Bluesky; the members' record on Buy Me a Coffee
