SOUND FAMILIAR?

Your fintech product has outgrown the way it was built.

Market data arrives late, or different screens show different numbers.
Trades, portfolios, and user accounts live in separate tools.
Every new feature risks breaking something users rely on with their money.
The platform was built fast for launch and nobody has hardened it since.
The developer or agency that built it has moved on.
You need a team that understands both the Rails backend and the React front end.

WHY CHOOSE STACKWORX

We have built a trading platform on Rails

Crypto WZRD is a trading and education platform we engineered on Ruby on Rails and React with real-time APIs. We bring that experience, and 10+ years of Rails in production, to your fintech product.

Data you can trust

Market data, trades, and portfolios come from clearly owned sources and stay consistent across every screen.

Rails and React, one team

The same engineers own the Rails backend, the APIs, and the React front end, so features ship without handoffs between vendors.

Long-term ownership

After launch we stay on as the team that maintains and extends the platform, instead of handing over and disappearing.

HOW IT WORKS

From first call to a platform you can rely on.

01
Discovery call
A 45-minute call on your product, your users, and where the current platform falls short.
02
Audit or plan
For an existing product we review the codebase first. For a new one we map data sources, accounts, and the first release.
03
Build in increments
Working features shipped in small, reviewable increments, so nothing users depend on breaks.
04
Own it
We maintain, monitor, and extend the platform long-term.
