Reyndex — Candidate email index

Reyndex connects to Gmail, identifies candidate emails, extracts structured profiles from PDF and DOCX resumes, and organizes them in a searchable table with filters, saved views, custom columns, formulas, direct editing, and AI enrichment.

I built and operate the product end to end: product direction and UX; the Next.js and TypeScript application; a multi-tenant FastAPI and PostgreSQL backend; Celery queues on Amazon SQS; transactional outboxes and reconciliation; leased AI-enrichment runs with workspace concurrency controls; Stripe subscriptions and a credit ledger; OAuth-protected read-only MCP access; and Terraform-managed infrastructure, observability, worker autoscaling, reliability, and cost control.

Production deployment docs (Linux + systemd + nginx + HTTPS) - transferable setup

Both MCP repos include an end-to-end deployment guide that's usable beyond "toy demos":

  • Full Linux setup: DNS -> nginx reverse proxy -> Let's Encrypt (certbot) -> health checks & logs.
  • Systemd-managed service: restart policies, log tailing via journalctl, simple upgrades.
  • Streamable HTTP: remote clients + connectors (including ChatGPT).
  • Optional OAuth: Auth0-backed flows for secure remote access.

This process is broadly transferable to any HTTP-streamable MCP server: swap the binary + port, keep the hardened server pattern.
