Mobile App Development for a Stock Trading and Investment Platform

Mobile App Development for a Stock Trading and Investment Platform

About the client

Finqalab is a Pakistan-based fintech company that runs a mobile trading platform for investors on the Pakistan Stock Exchange (PSX). Its app lets users open a trading account, track market indices, manage a portfolio, and place trades from their phone.

The Summary

Finqalab asked us to audit its trading platform before it scaled further. We reviewed the architecture, code quality, performance, and security of its Flutter-based mobile app, identified the issues that put growth at risk, and gave the team a clear roadmap to fix them. The platform later grew from under 200 to more than 20,000 active users and has processed over $17.6M in stock investments.

The Challenge

Finqalab was preparing to take its trading platform to market and needed confidence that the product could handle real growth. A trading app handles live money and market data, so any weakness in performance or security would directly affect investors and the company’s reputation.

  • Pre-Scale Validation

    The platform needed expert validation before scaling. Finqalab wanted an outside review of its Flutter-based mobile app before it committed to further growth.

  • Reliable User Experience

    User experience had to hold up under real use. Investors expect fast load times and accurate data on every screen, from the market watch to the portfolio and order placement.

  • Traders had no live data.

    Real-time stock tracking and market insight were absent, so investors made decisions on information that had already aged.

  • Financial-Grade Security

    Security had to meet the standard of a financial product. An app that manages trading accounts and investments needed its weak points found and closed before more users came on board.

The Solution

We performed a detailed technical audit of the platform that covered architecture, code quality, performance, and scalability. Our team ran static code analysis with SonarQube, tested the APIs with Postman, audited web performance with Lighthouse, and load-tested the system with JMeter. We identified the key issues affecting performance, reliability, and future growth, then delivered actionable recommendations to strengthen the platform and bring it in line with industry best practices.
