We developed a feature-rich P2P trading platform for a fintech company, utilizing React, Node.js, and Postgres. The platform includes primary and secondary market functionalities, offering users a seamless and secure trading experience. With React as the frontend framework, we created a highly responsive and interactive user interface. Traders can easily navigate through the platform, view market data, place orders, and monitor their investments in real time. Node.js powers the backend, ensuring high performance and real-time updates. It handles user requests, executes trading operations, and integrates with external APIs for market data, delivering efficient data processing and a smooth trading experience. Postgres serves as a reliable and secure database, storing and managing trading data. The platform enables users to participate in the primary market, facilitating the issuance and trading of financial instruments. Additionally, the secondary market feature allows users to trade these instruments among themselves, promoting liquidity and flexibility. Security is paramount, and we implemented industry-standard encryption protocols to protect user data and transactional information. Our collaborative approach with the fintech company ensured that the platform met their specific business requirements and provided a competitive edge in the market. In summary, our P2P trading platform, built with React, Node.js, and Postgres, offers primary and secondary market functionalities, a user-friendly interface, real-time updates, and robust security measures. It empowers traders to engage in efficient and secure transactions, enhancing their trading experience and facilitating growth in the fintech industry.
