Yea, I totally get it. The thing is agents change the game. You no longer need to worry about the learning curve or how best to implement.

Just point your agent at a machine0 VM and say "make a machine that does X", then you get code you can use to build on any nix box and you'll always get the same result.

Once you experience this, it's hard to go back to a "traditional" OS, you'll want to nixify everything :)

Upflow (YCW20) | Paris or Remote | Typescript, React, Heroku, Postgres | https://upflow.io Upflow is a new kind of payments platform for B2B businesses.

Upflow | Paris or Remote (CET -2 / +2) | Full-time | https://upflow.io

Getting paid on time represents a significant problem for B2B companies. Unlike consumer payments, where we've seen massive amounts of innovation in the form of companies like Venmo & Revolut, B2B payments remain archaic. We're on a mission to fix this, and bring delightful B2C experiences to B2B finance teams in the process.

We run on React / GraphQL / Node / Express / Postgres We're still really small (3 developers) and are looking for great hackers to work across the stack on problems ranging from payments, security, product and data.

Getting paid on time remains a significant problem for B2B businesses. We're on a mission to revolutionise how companies manage their outstanding payments. To do this, we're building a fully fledged payment platform from scratch - think Stripe but for traditional (non-tech) businesses.

It's an extremely complex and multi-faceted problem which affects almost 500,000 businesses across Europe.

------------------------------

I'm a full stack engineer with a founders mindset (I've interviewed at YC a few times). I have over 10 years of experience across the entire stack: frontend, backend, iOS, Android, UX and product.

I hold a masters degree from a top 10 university (Imperial College), have done stints in academia (PhD dropout), big companies (Apple & Morgan Stanley) and more startups than I can count.

The people that I work with tend to value my ability to go from a very loose set of requirements to a very high quality product in an extremely short amount of time.
