// who we are
Bilibala Shadowpaw Limited is a Hong Kong-based software company that does two things:
We build for others — turning IT dreams into working products. Web apps, automation, custom tools, whatever you need.
We build for ourselves — because sometimes the best products come from solving your own problems.
We’re small, fast, and we care about every line of code we ship. No bloat. No BS.
“(We care about every line of code we ship. No bloat. No BS.)”

// what we build
// some live. some in progress. all real.

Every coffee funds a late-night fix. Every Follow helps us stay visible. We don’t have investors — just a cat with opinions and a developer who runs on caffeine.
