Diaspora Remittance Fee Comparator — SL Corridors

Build a public web tool that lets diaspora senders compare fees and FX margins for sending USD, GBP, and EUR to Sierra Leone (SLE). Cover the main corridors used by the SL diaspora — including WorldRemit, Sendwave, Western Union, and MoneyGram — and surface the true delivered amount in SLE per 100 of sending currency.

• Mobile-first responsive web app, fast on a 3G connection
• Support at least four providers and three sending currencies (USD, GBP, EUR)
• Show: advertised fee, FX margin vs. mid-market rate, total delivered SLE per 100 sent
• Either daily auto-refresh from provider APIs/scrapes, or a clearly documented manual update workflow with timestamps
• Source code on GitHub under an OSI-approved license

• Deployed URL (Vercel, Netlify, or similar)
• GitHub repo with README and setup instructions
• Short Loom / video walkthrough (3–5 min) showing the comparison flow
