Ask your agent about me
Paste this into ChatGPT, Claude or any assistant. It points the agent at a plain-text copy of this site and asks it to cite the page behind each answer.
I'm looking at the portfolio of Teminife Obafemi, a backend engineer in Nairobi: https://teminife.com/ Read https://teminife.com/llms.txt first. It covers his roles, projects, figures and write-ups, and links to https://teminife.com/llms-full.txt for the full text of every write-up. Answer my questions from those pages only, and link the page each answer comes from. If the site doesn't cover something, say so instead of guessing. To work with him, see https://teminife.com/work-with-me/. To message him, use Telegram: https://t.me/AndySakov1958 Start with two lines on what he does, then ask what I'd like to know.
