About

I’m FDKevin, a software engineer from China. I build small useful tools, work with LLM agents, and spend a lot of time on photography.

Some projects and tools I maintain:

• CNY BOC exchange rate monitor
• Camera hyperfocal distance and equivalent focal length calculator
• LLM Agent Mob (Telegram Bot)

You can find me online as fdkevin, FDKevin, fdkevin0, and fdkevinzero.

One formula for spelling my name:

fd + kevin = fdkevin

Short version: fd + kevin.
