Innovecs partnered with an Indian online brokerage to rebuild the web and mobile frontends of its trading platform. The project transformed a fast-grown startup interface into an enterprise-ready, multi-platform system with improved responsiveness, advanced charting, and reusable components — delivering a stable foundation for large-scale retail trading.

About customer

Our client is a leading digital brokerage that provides trading and investment services through web and mobile platforms. The company serves a rapidly growing investor base in Asia, offering access to equities, derivatives, and other financial instruments with a strong emphasis on usability and scale. 

Project Summary

The client’s fast-growing trading platform, built quickly during initial scaling, suffered from an outdated and fragmented codebase. Innovecs was engaged to upgrade it to an enterprise level across both web and mobile, ensuring scalability, stability, and a seamless user experience. 

Challenge

  • Outdated, startup-grade frontend unable to scale with rising demand.

  • Need for enterprise-level architecture to support high-frequency trading workloads.

  • Poor responsiveness and UI performance undermined user trust and experience.

Solution

  • Built dedicated web and mobile teams, covering recruitment, delivery, and quality assurance.

  • Designed a new frontend architecture from scratch, tailored for high-load FinTech requirements. 

  • Integrated TradingView for advanced charting, enhancing usability for professional traders. 

  • Developed native mobile apps (Android in Kotlin, iOS in Swift) for high-performance trading on the go. 

  • Delivered a reusable UI library to ensure consistent design and accelerate rollout of future products. 

  • Established release management and QA processes to support continuous delivery.
