I am building a real-time prediction-markets platform and need an experienced UI developer who is comfortable designing around a WebSocket-first architecture. The work starts with the foundation—authentication, database design, and a clean data pipeline that pulls live odds from Polymarket, Kalshi, and PredictIt via their public APIs. Once the back-end hooks are in place, the focus shifts to the core interface. I want a responsive dashboard that streams prices without page refreshes, surfaces immediate arbitrage opportunities (I’m primarily interested in price differences), and highlights unusually large trades. A lightweight whale tracker that flags outsized orders in near real-time will help users react quickly. Social engagement is equally important. The UI must let users post their own predictions, climb a public leaderboard, and follow other traders to watch their activity and returns over time. These pieces should feel native to the overall flow, not bolted on later. After the main modules are functional we’ll round things out with user-configurable alerts, a final UI polish pass, QA, and basic launch prep. I have a 7–8 week timeline in mind, so an iterative delivery plan that shows progress every week will be essential. If you have shipped interfaces that stream live data, leveraged WebSockets heavily, or integrated similar betting/market APIs, please share links or repos. A brief note on your role in those projects will help me gauge fit. I value clean, modern design, efficient state management, and thoughtful component architecture—show me you do too and we’re off to a great start.

Hi, This is exactly the kind of product I like working on—real-time, data-dense interfaces where performance and clarity matter. I’m comfortable designing and building UIs around a WebSocket-first architecture, and I’ve shipped dashboards that stream live data without refreshes, handle rapid state changes, and stay readable under load. Why Choose Me I focus on results, not just delivery – whether that’s conversions, usability, or performance, every decision has a purpose. Clear communication – you’ll always know what’s happening, what’s next, and where things stand. No guessing. Modern best practices – clean UI, scalable structure, and tools chosen for long-term maintainability. Detail-oriented – I sweat the small things (spacing, responsiveness, edge cases) so the final product feels polished. Happy to discuss architecture or trade-offs before starting. Best Regards ADEEL

Hi, We’ve built several real-time web apps using WebSockets and similar APIs, including a product that integrated with multiple betting platforms to aggregate odds and deliver them to users. We also developed a responsive UI that allowed users to place bets directly from the odds cards, which is similar to your idea of surfacing arbitrage opportunities. We can handle the entire backend and frontend development, as well as DevOps and UI/UX design, ensuring a fully integrated solution. We also have a dedicated QA team to perform manual and automated testing, so you can launch with confidence.

I’ve worked on live data dashboards before that pulled streaming market info using WebSockets, so I understand the need for a smooth, refresh-free UI that feels immediate and reliable. For example, I helped build a real-time sports betting interface that tracked odds and highlighted arbitrage opportunities, while keeping the experience sleek and easy to navigate. Starting with clean authentication and database flows tied to API data is smart—it ensures the UI won’t need patchwork fixes later. How are you planning to handle data normalization across the Polymarket, Kalshi, and PredictIt APIs? I’ve found a unified data layer early on makes UI logic simpler when streaming prices and flagging trades. For state management, a solution like Zustand or Redux Toolkit usually keeps components isolated but responsive—especially important with live whale tracking and a dynamic social feed. Implementing public leaderboards and follow features as first-class UI elements will help users engage naturally without feeling like an afterthought. Breaking the work into weekly milestones with working, demonstrable pieces will keep things on track and avoid surprises. I’m ready to jump in and start building out the foundation right away.

Hi, This is an interesting project. A WebSocket-first prediction markets UI is exactly the kind of problem I enjoy working on. I have built real-time dashboards where prices, events, and user activity stream live without refresh, so designing around WebSockets, efficient state management, and performance is very familiar territory. I can help you: - Stream live odds from Polymarket / Kalshi / PredictIt - Surface price differences for arbitrage - Flag large (“whale”) trades in near real time - Build a clean, responsive dashboard with efficient state management - Add social features (predictions, leaderboard, follows) that feel native I can work comfortably within your 7–8 week timeline and share progress every week. If useful, I am happy to explain how I would structure WebSockets and UI state to keep the app fast under live data. Best, Rakesh

Hi, I can build the UI foundation for a WebSocket first prediction markets dashboard and keep it clean, stable, and easy to extend across new modules. I have shipped React interfaces that stream live data, handle fast updates without refresh, and keep state predictable under heavy real time traffic. I can work closely with your back end hooks to ensure the UI stays responsive while prices, spreads, and trade events update continuously. Deliverables. - Responsive React dashboard that streams prices and highlights price differences and arbitrage opportunities in real time. - Whale tracker and large trade feed with near real time flags and clear visual priority. - Social layer UI for posts, leaderboard, following, plus alerts UI and final polish with weekly progress demos. Do you already have WebSocket event formats defined, or should I propose the message schema for prices and trades.

Hi! I’m a strong fit for this and comfortable building real-time, WebSocket-driven UIs around live market data. I’ve worked on dashboards that stream prices without refresh, handle fast state updates, and surface signals like spreads, large trades, and alerts in a clean, usable way. I can help design and implement a responsive interface that streams odds from Polymarket, Kalshi, and PredictIt, highlights arbitrage opportunities, and flags whale activity in near real time. I’m also comfortable building social features like predictions, leaderboards, and follow systems so they feel native to the core trading flow. Are you already set on a front-end stack like React with a specific state-management approach, or is that still open? I work iteratively, ship weekly progress, and focus on clean component architecture that scales as features grow. Happy to share examples of live-data or market-style interfaces I’ve worked on and explain my role in each.

Hi, I’m a UI developer with hands-on experience building real-time dashboards and WebSocket-first interfaces for streaming data. I’ve shipped live-market UIs with robust state management, modular components, and clean data pipelines, and I’ll set up authentication, scalable database design, and a live odds pipeline pulling data from Polymarket, Kalshi, and PredictIt. The frontend will be a responsive dashboard that streams prices without refresh, surfaces near-term arbitrage opportunities, and highlights unusually large trades, while weaving in social features for posting predictions, a public leaderboard, and trader follows with smooth UX. I’ll structure the UI around a clean component architecture and efficient data flows to support iterative weekly progress and QA within your 7–8 week plan. What latency targets and API rate limits should I plan for, and do you have preferred data-hydration strategies for the live streams? Best regards,
