Karate Kata Referee Voting App (7 Judges + Main Tatami Controller)

@leadconcept

Greetings, I understand you need a lightweight, rock-solid web app for karate kata competitions, supporting up to 7 judges submitting RED/BLUE votes in real time, with a central Tatami Controller screen showing totals, live connections, and winner highlights, while handling unstable Wi-Fi, vote locking, session isolation, and automatic reconnections. Our approach would use a React or Vue frontend for both judges and controller pages, a Node.js or Python (FastAPI) backend with WebSocket support for real-time vote streaming, and server-side state persistence (in-memory with optional lightweight database like SQLite) to prevent vote loss on refresh or reconnection. Judges join via QR/session code, votes are locked after submission, and the controller page can reset or manually close rounds. Automatic reconnection ensures a judge or controller returning mid-round sees current vote state without duplication. Our team has built live-score and voting systems with real-time WebSocket updates, reconnection handling, and minimal, high-contrast interfaces optimized for events. Let us connect to review your timeline and deployment environment. The current bid amount is a placeholder to start the conversation. Regards Yasir LEADconcept PS: Let me know, if you want to see our team past work to determine our skills/expertise or past customer's references.

Hi There, 1.I am looking for a small, rock-solid web application to be used duri... ==> We understand your need for a real-time judging app. We have delivered similar real-time systems before. One past project had a unique feature where the controller could see a private readiness check from each judge before starting the vote, ensuring everyone was ready. We got the idea for the roles. The Controller gets a secure dashboard to manage the match and see live votes. Judges will join with a code and see just two big buttons, RED and BLUE, which makes voting fast and simple. For stability, we will use Node.js with WebSockets. This is perfect for instant updates and handling unstable Wi-Fi. Every vote is saved on the server instantly, so a browser refresh or network drop wont lose data. ## Queries : 1. If a judge loses connection before voting, should the controller be able to manually close the round, or must they wait for all assigned judges to vote? ## Initial Project Structure : - Controller Login - Controller Dashboard - Judge Session Join - Judge Voting Page - Judge Voted Screen We use advanced AI tools (Cursor, Claude, ChatGPT) to speed up coding and reduce manual work hours. We pass these time-savings to you, providing a high-quality app at a very competitive price. Waiting for your reply. :-) Regards, Ghanu & Samir. KESHAV INFOTECH

Hi I'm Divya Manocha, the CEO of CodeNomad and our professional history of over 12 years shows that we're no strangers to successfully delivering complex projects. Your Karate Kata Referee Voting App appeals to us not only because of the technological challenges it presents but also because we believe in leveraging technology to bring innovation in different domains. With a skilled team that has expertise in CSS, HTML, JavaScript, Node.js, React.js, Vue.js and more your project requirement is well within our skillset. Our competency with developing applications using real-time communication makes us the best choice for this project. We've ample experience working with WebSocket-based solutions or equivalent push mechanisms like SignalR etc. We fully understand the need for a reliable system that won't fall apart due to spotty Wi-Fi or connection loss and can store votes server-side so none are lost during refreshes or disconnections. Moreover, our thorough knowledge of handling data security and session isolation would ensure no unauthorized devices join the session to maintain system stability. As for reconnection and vote loss prevention, we implement robust strategies like involving Judge-specific session codes so even if they reconnect after dropping connection they don't lose their votes. Thanks....

As a seasoned full-stack developer with over 13 years of experience, I have traversed numerous projects that align closely with your requirements. Considering this Karate Kata Referee Voting App project, my expertise in real-time streaming and secure application design in the tech stack of Node.js, React.js as well as Websockets would be the perfect fit. I specialize in developing clean, robust, and scalable web applications that function optimally across devices and networks which precisely meets your demands. Handling spotty Wi-Fi is not a problem either because I ensure automatic reconnection through implementing Websockets or an equivalent push mechanism. Should a connection drop or loss occur momentarily, my system guarantees no vote data will be lost upon refreshing the page; ensuring every vote is securely stored server-side. I also implement efficient duplicate vote prevention and session isolation protocols to maintain the integrity of the voting process itself.

@Julian29

Hello, HAVE HANDS-ON EXPERIENCE WITH SUCH PROJECT I bring 15+ years of proven experience building real-time, multi-user web applications, and I fully understand your goal of delivering a rock-solid, low-latency voting system for karate kata competitions that is intuitive, reliable, and resilient under spotty Wi-Fi conditions. -->> Judge interface via QR/session code with single-tap RED/BLUE vote -->> Tatami Controller with live vote totals, individual votes, and winner highlight -->> Real-time updates using WebSockets with automatic reconnection -->> Session isolation, duplicate vote prevention, and server-side vote persistence -->> Lightweight backend deployable locally or on a cloud instance My approach emphasizes clean architecture, WebSocket-based push communication, persistent session state on the server, and client-side reconnection logic to ensure no votes are lost even if a judge disconnects. I would approach your project by first defining session and vote data models, then building the controller and judge interfaces with responsive, high-contrast design, followed by backend real-time state handling, reconnection/retry logic, and venue-tested deployment instructions. I’m confident I can successfully implement this project from start-to-finish. Let’s create a voting system that is fast, reliable, and competition-ready. Thanks & regards Julian

@kishanbwts

I can build the voting app with a React front end and a Node.js backend using WebSockets for real-time updates. Judges join via a session code and vote with one tap. The controller logs in with a PIN, creates sessions, and sees live votes with totals and clear winner display. For unstable Wi-Fi, I will implement automatic reconnection and keep votes server-side. This means votes remain saved if a judge loses connection or refreshes. When a judge reconnects, the server checks if they already voted to prevent duplicates and locks their vote. The controller page also maintains session state on refresh. I’ve built a similar app for a martial arts tournament where live scoring and judge voting needed the same reliability and instant updates. That project handled session isolation and vote lockout under fluctuating Wi-Fi with success. Would you prefer a self-hosted deployment on a local laptop or a cloud instance? Also, should the controller PIN be configurable or fixed? I estimate this can be completed solidly within 2-3 weeks for a fixed price of $1800. Ready to start as soon as you’re set.
