I built an AI data extraction engine and E2E encrypted SMS router in Rust

I recently launched SendStackr. The original itch came from my time working at an agency that managed multiple Upwork accounts and a "phone farming" operation (around 50 physical devices). We needed to centralize inbound emails and forward SMS (mostly for 2FA/OTPs), but the existing tools were either prohibitively expensive, forced us to set up individual webhooks per device, or timed out when trying to pipe heavy unstructured data through standard no-code wrappers. To solve this, I built my own routing and extraction engine. Instead of relying on standard APIs, I wrote the backend entirely in Rust, building custom SMTP and IMAP servers to ingest the emails natively. It uses Graph RAG to read unstructured PDFs, raw HTML emails, and webhooks, extracting the exact variables needed and return

Instead of relying on standard APIs, I wrote the backend entirely in Rust, building custom SMTP and IMAP servers to ingest the emails natively. It uses Graph RAG to read unstructured PDFs, raw HTML emails, and webhooks, extracting the exact variables needed and returning them as strictly mapped JSON.

I also just released an Android Node app to handle the physical phone problem (SMS and push notification forwarding)
