FinTech Platform Development with React

CityFalcon is a personalised business news app for market analysis. As software for financial insights, it helps users track relevant content on stocks, private companies, and locations. Our team joined during the main development stage to support product optimisation. As a result of our cooperation, the platform gained new features and an elevated user experience.

About the project

CityFalcon engaged us for financial app development to refine their end-to-end business news application. Our scope of work included system performance optimisation, debugging, and new functionality roll-out (e.g., AI-driven alerts and analytics dashboards). The delivered product provides users with real-time market insights, offering rich coverage, including stocks, ESG, filings, sentiment scores, and AI summaries, across desktop and mobile.

Client's needs

Our main challenge during the fintech development process was to implement data-intensive features while ensuring fast and reliable React-based platform performance. We focused on the system scalability as real-time financial content grows and needs to be structured. To add AI-powered sector classification, we also collaborated on the DCSC web app development as a part of CityFalcon’s ecosystem.

Key project requirements

- Support FinTech software development by implementing new features

- Resolve long-standing bugs

- Optimise performance, considering a data-heavy interface

- Develop interactive and customisable chart components

- Ensure financial data visualisations maintain a high-performing UX

Our approach to financial software delivery

Frontend for a custom FinTech app

Working with React, JavaScript, SCSS, Redux, Bootstrap, Axios, and Moment.js, we were responsible for building and refining complex data-driven features while focusing on performance and scalability. We collaborated with product and design teams to create functional components that supported efficient releases.

Data visualisations for real-time analytics

A major part of development involved creating interactive charts for financial insights visualisation. After evaluating several libraries like Recharts, D3.js, and Chart.js, we selected Plotly.js for its flexibility and performance. We then developed modular visual components with advanced styling and dynamic tooltips, enabling users to interact with large volumes of financial data.

Bug fixing

The project required us to resolve long-standing bugs that were affecting the app’s stability. By improving logic, structure, and responsiveness, we boosted the platform’s functionality and reliability.

Performance optimisation

Given the app’s scale and the volume of financial data processed, we focused on performance tuning at the component level, restructured slow-rendering views, and applied targeted optimisations to handle large datasets effectively within the frontend layer.

Business impact

The result of our collaboration is an AI-powered platform with improved UI/UX. With highly interactive, visually tailored charts, the application also maintains smooth performance and easily adapts to new feature requests.

Using news API, interactive chatbot, and Sector Classification, the upgraded CityFalcon app transforms large volumes of financial content into structured data and personalised insights for data-backed business decisions.
