bellwize

BellWize is a live B2B SaaS I built and launched solo: DB schema, REST API, Google OAuth and magic-link auth, row-level security, and transactional email alerts via Resend.

The core is the Churn Shield engine, a 4-stage pipeline (ingestion, feature extraction, scoring, alerting) that turns 100+ client signals into health scores and early-warning alerts. Integrated Paddle for payments, configured custom-domain email (SPF, DKIM, DMARC) and deployed on Vercel. Owned product, GTM and outreach end to end.
