I'm looking for someone experienced in the fintech industry who can mentor me.

I'm particularly interested in anyone who has worked or works for Visa / Mastercard, Stripe, Adyen, PayPal, Square, FIS, Authorize, Paddle, Plaid, or any relevant company. I'm also looking for someone who has knowledge of how startups can negotiate with banks to get into their networks.

About me: I'm based in the US, studied computer science in university and I'm about to graduate. I am looking for mentorship in order to understand the industry better and what path to take in my career. This past year I've become fixated on the payment processing industry. I read some books on payments processing so I can understand how the system works.

I'm interested in building a technology startup in this space to take on emerging markets.

Hi HN!

Code reviews today are line-by-line diffs. This format makes reviewers focus on individual changes to catch bugs, style issues, and bad variable names, rather than the bigger picture of what the code is doing and why.

However, I don’t think that’s what code reviews are for. Tests (and angry users) catch bugs. Linters catch style issues. And nitpicks almost always bog down the review and make it take longer for the code to merge.

I believe that the point of a code review is to help teammates understand how the author is trying to achieve their goal, whether that’s a bug fix, a new feature, or a refactor. A good review requires understanding the narrative behind a change, determining whether the structure of a pull request reasonably fulfills that narrative (interface changes, new data structures, etc.), and deciding whether the team is OK with maintaining this new shape of the codebase.

The current pull request interface makes this hard. It's just a wall of unordered diffs that you're left to piece together by jumping between files. When reviewing a pull request from a teammate, I found myself spending more time reconstructing the big picture of the changes than reviewing the code itself.

So I built Haystack to help with that. It breaks down a pull request into logical chunks and lays them out on an infinite canvas. It guides you through the changes as a structured visual story, helping you focus on architecture, intent, and maintainability instead of chasing nits. I hope that Haystack makes code reviews less of a last-minute, unwanted chore. And if it doesn’t, I want to hear about it!

If you’re interested:

1. Take a look at the demo playground https://haystackeditor.com/playground

You can connect all your MCPs through MetaMCP: a unified middleware MCP to manage all your MCP connections.

Hi all I am James glad to share some more progress on the project.

Features include:

- GUI app to manage multiple MCP server integrations all together.

- Support ANY MCP clients because MetaMCP is a MCP server.

- Support multi-workspace: e.g., activate a workspace of DB1 or switch to DB2 in another workspace, preventing polluting context of DB1 to your MCP Client.

- Tool level toggle on/off

- Trace tool execution logs for developers

And more potential to build this "OS" around MCP through MCP!
