I’m planning to launch a full-featured cryptocurrency trading service and I need a developer who can take it end-to-end on both web and mobile. The heart of the product is fast, reliable real-time price updates so users see every market move the moment it happens. Here’s what I’m after: the web version should run smoothly in any modern browser, while the companion mobile app (iOS and Android) matches the same functionality and look-and-feel. From account creation through order placement, every screen must feel secure, responsive, and intuitive. If you’ve worked with WebSockets, REST APIs from major exchanges, or integrated live charting libraries, that’s exactly the background I’m looking for. Although real-time pricing is the non-negotiable feature, I’m open to your recommendations on extras such as portfolio views or news feeds if they fit cleanly into the architecture. A clean codebase, clear documentation, and a straightforward deployment workflow (think Docker or similar) will make this project a success. Deliverables • Web trading interface with real-time crypto prices • Native or cross-platform mobile app mirroring web functionality • Admin-ready back end for user, order, and security management • Deployment guide and hand-off documentation If you’re comfortable building performant trading stacks and can demo previous work with live price feeds, let’s talk about timelines and milestones.

With more than a decade in the tech arena, I’ve successfully executed over 100 projects - many of them in mobile and web development- including Flutter, Android, iOS, React and PHP - all relevant to your crypto trading platform. Seamlessly integrating real-time pricing across platforms will be a core strength I bring to the table. Not only have I worked with Websockets but I have also integrated REST APIs from major exchanges, helping me build high-performing stacks that can incorporate live charting libraries and other value add-ons you may consider. To ensure fluidity between your web and mobile app, I recommend adopting cross-platform technology using Flutter and React. With my expertise in deploying clean codebase on cloud platforms like Docker, we can guarantee accelerated project success while maintaining ease of scalability and stability. Beyond mere development expertise, I understand the importance of efficient collaboration. My strong communication skills and fast delivery strategies should keep us working productively throughout the duration of this project. Let's partner up to turn your vision into a high-performing reality.

Hi. Building a full-featured crypto trading service requires solid web and mobile platforms that handle real-time data, secure transactions, and a smooth user experience across devices. I have hands-on experience in both Web Development and Mobile App Development, which directly align with your project needs. I've built complete web applications using .NET Core and React for responsive frontends, and developed mobile solutions that integrate with backend APIs for live data feeds and user authentication. My backend work includes designing scalable REST APIs, database optimization with SQL Server and MongoDB, and deploying cloud-ready systems on Azure—all essential for a trading platform that needs performance and reliability. Here's how I'd approach this: - Gather detailed requirements for trading features, user roles, and security protocols to define the platform scope - Build a secure backend API to handle user accounts, transaction processing, and real-time market data integration - Develop responsive web and mobile interfaces that provide seamless trading experiences on all devices What third-party APIs or data providers are you planning to integrate for market feeds and wallet management? I'm ready to start immediately and can discuss architecture, timelines, and your specific feature priorities through Freelancer messages. Best regards, Jordan Rafael G.

Hi, your project "Crypto Trading Web & Apps" is clear, and I can take care of the implementation. My focus would be a clean technical setup around the database, API, and integration points. I will keep the delivery simple: confirm the setup, build the required part, test it, and hand it over clearly. The listed skills point to Mobile App Development Web Development Cryptocurrency, so I would keep the implementation aligned with that. Before starting, I would confirm: Where should the completed work be deployed, and what hosting access will be provided? Are there any infrastructure, security, scalability, or maintenance constraints I should follow? What existing code, documentation, assets, or account access should I review before starting? Best regards, Houssame
