FINTECH SOFTWARE DEVELOPMENT

Fintech software development on Ruby on Rails, built and maintained by one team.

For fintech and trading products that need real-time market data, portfolio and account tools, and a platform that stays reliable as users grow. We build new fintech platforms on Rails and React, take over existing ones, and own them long-term.

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.

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.

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.

FAQS

Before You Get Started

What does Stackworx do?

We build and take ownership of the systems your business runs on: custom Shopify apps, Ruby on Rails platforms, third-party integrations, and practical AI workflows. Most clients come to us when off-the-shelf apps and quick fixes stop scaling.

Do you only build new products, or can you take over an existing system?

Both. A large part of our work is taking over existing Rails and Shopify codebases, stabilizing them, and then extending them. We start with a technical audit so you know exactly what you have before anything changes.

How do you add AI to a business that already has software?

We add AI inside the systems you already run rather than bolting on a separate tool. Typical work includes content generation, document and data extraction, product recommendations, and support automation, shipped as a focused AI Integration Sprint with measurable outcomes.

How do engagements usually start?

Most clients start with a Technical Audit or an AI Integration Sprint. From there we move to an MVP build or a dedicated product team on a monthly retainer, depending on how much ongoing work you have.

Which industries do you work with?

Mostly ecommerce brands on Shopify and SaaS companies in PropTech, InsurTech, and FinTech. Our platforms have processed 32M+ transactions and serve 20,000+ real estate agents.

Where is your team, and how do you work with US clients?

Our senior engineering team is based in Lahore, Pakistan, and we contract with US clients through Stackworx LLC, our Wyoming company. We work across time zones with regular overlap hours, async updates, and long-term ownership of the systems we build.
