Summary: A suite of 20+ developer utilities that run entirely in
the browser. No uploads, no server, no data leaving your machine.
What I did: Built the full stack — Next.js frontend, Web Workers
for heavy processing (formatting tens of thousands of lines of JSON,
PDF manipulation, hashing) so the UI never blocks. Every tool works
offline after first load.
The no-upload promise is the strongest part. I'd make the offline state visible in the UI, so someone working with sensitive JSON or PDFs can see that the file stays on their machine before they drop it in.
The modular motion language carries the cyber-security story nicely—the stacked forms make the service categories feel tangible. I also like how the compact mobile view keeps the navigation legible without flattening the brand.
