Small utilities I built and keep online. Each one runs in your browser and has its own short link.

sufi.my/speedtest
Internet Speed Test

Browser-based estimate of latency, jitter, download and upload throughput against Cloudflare's edge.

Runs in your browser. Speed payloads come from Cloudflare's public speed-test endpoints; IP/location lookups use public geo APIs. Nothing is stored by sufi.my.
sufi.my/resume-builder
ATS Resume Builder

Write a resume in Markdown, preview it as an ATS-friendly layout, and export a clean PDF.

Runs entirely in your browser. Your draft is saved in this browser's local storage and is never uploaded.
sufi.my/onion-directory
Onion Directory

Official Tor .onion addresses of well-known organisations, each checked against the organisation's own website.

A static list. Reachability is checked at build time over Tor, not from your browser.
sufi.my/systems-lab
Systems Lab

Interactive demos of backend failure modes: incident debugging, webhook retries, log traces, and payment architecture.

Simulations run in your browser. The reachability probe sends one request to each listed product domain.
