Kat-Katha — NGO Giving Platform

Kat-Katha does deep, story-driven work with women and children on Delhi's GB Road, but relied on a static site only a developer could update. Giving was friction-heavy, campaign progress was invisible to donors, and every story or program change needed code.

Built a full-stack Next.js 15 site with an end-to-end Razorpay flow — order creation, HMAC signature verification, and an idempotent settlement webhook writing to a Postgres donations ledger — feeding live per-campaign progress bars. A custom JSONB-backed CMS and admin panel let staff manage stories, programs, campaigns, team, and press without a developer, and the public site falls back to seeded content if the database is ever unavailable.

• 01Donors give in a few taps and get an instant thank-you email; campaign totals update live within seconds of a captured payment
• 02The team self-publishes stories, programs, and campaigns through a custom admin — zero developer involvement for content
• 03Donation pipeline hardened end-to-end: HMAC-verified webhooks, idempotent settlement with an append-only event audit trail, per-IP rate limits, and honeypot spam defense
• 04Public pages stay up even if the database is down — cached reads gracefully fall back to seeded content
