Vectius
The operating layer for a company's SaaS stack — tools, credentials, invoices, budgets, and renewals in one encrypted system of record. Built and shipped for a client.

The problem
Early-stage teams manage their SaaS stack through scattered spreadsheets, shared password vaults, and half-read PDF invoices — credentials, spend, and renewals all live in different silos.

Built a complete SaaS operations platform: AES-256-GCM credential vault, invoice workflow with OCR + LLM autofill and approval chains, spend analytics, renewals calendar, and a GPT-4o-mini assistant for natural-language queries over live data.
