MUSTAFA_
DEMIRAY

role: full-stack software engineer

location: Istanbul, Türkiye

I build web platforms, mobile products, developer tools, and data workflows. I’ve spent more than eight years moving from enterprise systems to blockchain research, developer relations, and products I own end to end. AI tooling supports the work; engineering judgment still drives it.

Products running in production

Two products I took through product decisions, interface work, backend systems, and release.

[process: attim] ● Live

$ cat ./attim/README.md

type: AI publishing

ATTIM

Made something with AI? ATTIM puts it online at a link anyone can open. Share it, update it, and keep it.

dependencies:

FastifyPostgresCloudflare R2ReactVite
  • [ok] Publish first: get the live link before creating an account. It works for up to 12 hours; save it to a free account to keep it.
  • [ok] Works with the AI you already use: ChatGPT, Claude, Gemini, Grok Bot, Perplexity, Cursor, and more.
  • [ok] A link is just the start: share it, protect it with a password, and update it without changing the link. See visits and choose whether others can remix it.
  • [ok] An ATTIM profile: a free page with your links and the things you make with your AI.
