VADER-Sender

A production-grade form submission microservice built to replace third-party services like Formspree and Formbricks. VADER-Sender receives form submissions from landing pages, stores them as leads in PostgreSQL via Prisma ORM, and forwards them to destination emails through the Brevo transactional API. It includes Redis-backed rate limiting and idempotency, comprehensive security hardening with Helmet and CORS, and full observability through Grafana Cloud with Alloy and prom-client. Deployed on Oracle Cloud's Always Free Tier — zero cost, full control.
