Our work - Proven solutions for real-world problems.

From full stack web platforms to cross-platform mobile apps, we deliver software that solves real business challenges. Here are some examples of what we do.

Case studies

Financial Services

Web development, Full stack

Full stack web platform with real-time data

We partnered with a financial services company to build a full stack web platform from the ground up, using React and TypeScript on the frontend with a Node.js backend.

The platform needed to handle real-time data feeds, complex filtering and reporting dashboards — all while maintaining a fast, responsive user experience.

We architected the system with scalability in mind, implementing server-side rendering with Next.js for performance-critical pages and WebSocket connections for live data updates.

The result was a robust, production-ready application that the client's team could confidently maintain and extend going forward.

JJP Engineering felt more like an extension of our own team than an external partner. They understood our technical challenges and delivered a platform that exceeded our expectations.

Backend development

Automated data collection platform

We have worked with multiple investment firms who need reliable, large-scale data collection to inform critical investment decisions.

Using Node.js, we built a suite of automated data collection tools that scrape, parse and normalise information from dozens of web sources, delivering millions of structured data points.

The data is processed through a pipeline we developed in close collaboration with the client's investment team, ensuring the right information is captured in the formats they need.

The data platform JJP built gave us market insight we simply could not have obtained through other channels. It directly informed a major investment decision.

Web & mobile development

Web and mobile application development

We worked with an ambitious e-commerce startup to design and build their entire digital presence — a responsive web application and companion mobile apps for iOS and Android.

Using React for the web storefront and React Native for mobile, we delivered a consistent, high-quality user experience across all platforms while sharing a significant portion of the codebase.

The Node.js backend handles inventory management, order processing and payment integration, all built with TypeScript for reliability and maintainability.

JJP Engineering delivered both our web and mobile apps in a single engagement. The shared codebase approach saved us months of development time.

Hands-on web and mobile consulting

We are currently embedded with a large multinational company, helping them modernise their web and mobile applications following a major acquisition.

Our team provides day-to-day development support, technical leadership and architecture guidance — working as a seamless extension of their in-house engineering team.

With deep experience across React, React Native, TypeScript and Node.js, we help the client ship features faster while improving code quality and developer experience.

Having JJP embedded in our team has been transformative. They brought expertise and pace that accelerated our roadmap significantly.
