Hello, engineering

This is the first post on the NexPay engineering blog. The marketing blog is where we talk about the company, the customers, and the corridors. This space is for the systems underneath.

What we’ll write about

A few areas we expect to come up often:

• Payment rails. How AUD, USD, BRL, CLP, COP and friends actually move — the boring middleware behind a wire that lands at a school’s bank.
• FX and rates. Pricing curves, mid-market sourcing, and why we never use hardcoded fallback rates.
• AI infra. Our MCP server, the agentic flows that read inboxes and reconcile statements, and the eval harnesses that keep them honest.
• Compliance as code. AUSTRAC, AFSL, sanctions screening, KYC — modeled in the type system, not bolted on.

What this isn’t

It isn’t a feed of release notes, it isn’t recruiting fluff, and it isn’t a parade of new tools we tried for a weekend. If a post lands here, it’s because we want to read it ourselves in two years.

More soon.
