Finance

SuppMoney — personal finance for Brazil on web, iOS, and Android. Founder, 2025 to now.

• Live bank accounts synced through Pluggy Open Finance.

• WhatsApp AI assistant on the Pi agent harness: answers spending questions, sends alerts, and connects banks in chat, resuming durably on Cloudflare Workflows and Durable Objects.

• Merchant-level transaction intelligence: every name and category decision recorded with source and confidence, classified by Decision AI models (TypeSafe Jev, Clef Flash) whose calibrated probabilities are gated per model against user-labeled evals at ~90%+ precision.

• Domain logic on Effect TS: typed errors, scoped resources, bounded concurrency, and cancellation forwarded to every provider call.

• Budgets recomputed monthly per category from usual spending; an MCP server lets the user's own AI query and act on their finances.
