SSL Checker

Full-stack SSL certificate monitoring solution. The Next.js dashboard (deployed on Vercel) provides pages for URL management, check history, email alert configuration, and weekly report generation. The Express API handles automated SSL checks via cron jobs, stores data in PostgreSQL with Prisma, sends email alerts through Resend, and supports Docker deployment with a multi-stage Dockerfile and docker-compose setup. Includes authentication with JWT and bcryptjs, input validation with Zod, and unit tests for core SSL logic.
