Hi! I noticed Dukandar’s main requirement is real-time inventory visibility that continues working when stores go offline. I can build the stock-sync layer so every sale updates inventory and sales history across connected devices without manual refresh. ++ What I’ll build: → Live Stock Tracking — exact current stock per SKU with latest sales history side by side → Real-Time Updates — WebSocket/event-driven updates targeting sub-2-second LAN latency → Offline-First Sync — local transaction queue with automatic cloud synchronization when connectivity returns → Conflict Handling — documented sync strategy to prevent duplicate or incorrect stock updates → Sales History — SKU-level history with 30-day CSV export → Live Dashboard/API — responsive interface for managers and cashiers → Scalable Backend — optimized database, change listeners and transaction handling → Reliability Testing — test dataset/script covering 500+ concurrent transactions → Deployment — production-ready code, documentation and IT deployment guide Why me: I focus on production-ready, real-time systems where data consistency, offline reliability and performance are critical. Happy to discuss your existing Dukandar architecture and recommend the best stack and implementation plan. — Abhishek

Hello, I’m a full-stack developer with 10 years of experience building production-ready inventory, POS, ERP, and real-time business applications. For Dukandar, I recommend Node.js with PostgreSQL, WebSockets, and a React.js dashboard. This stack is well suited to high-frequency stock events, instant device updates, and controlled offline synchronization. I would design an event-based inventory ledger that links every quantity change to its originating sale, while local queues preserve transactions during connectivity loss and reconcile them safely after reconnection. The solution will include secure REST APIs, efficient database indexing, documented conflict-resolution rules, 30-day SKU sales exports, and automated load tests covering 500 concurrent transactions. Let’s discuss Dukandar’s existing technology stack, database structure, and offline conflict priorities. Best regards

Hi, I can build the offline-first stock sync you need: a Laravel/Node backend with websocket or SSE push so scans reflect on every screen in under 2 seconds, local writes queued and auto-synced with conflict handling once connectivity returns. I'll design clean SKU + sales-history tables, load-test with 500+ concurrent transactions, and include a CSV export for 30-day sales history plus a deployment guide your IT team can follow. I can start now and deliver in 5 days.

Hi, I can build the real-time inventory layer for Dukandar with a Laravel/MySQL backend and an offline-first synchronization strategy, while keeping the scope focused specifically on stock and sales history. The solution will provide: • Current stock + latest sales history per SKU • API-based sale/stock updates • WebSocket/push updates without manual refresh • Offline transaction queue with automatic reconnection sync • Documented conflict-resolution rules • 30-day SKU sales-history CSV export • Concurrency/load testing and deployment documentation I would structure stock changes as transactional records rather than simply overwriting quantities, allowing each inventory update to remain traceable to the corresponding sale. For offline operation, transactions will be stored locally with unique identifiers and sync status so reconnecting devices can safely retry without creating duplicate sales or stock deductions. I’ll also benchmark the real-time flow against the required sub-2-second target and provide test results for concurrent transactions. Proposed stack: Laravel/PHP, MySQL, REST API + WebSockets, with the client-side sync layer adapted to your existing Dukandar application

Hello, I can build the real time offline first inventory tracking and live stock sync system for Dukandar. My plan is to design an offline first architecture using Node js with WebSockets on the backend and local SQLite or RxDB storage on the client app. I can write local transaction queues that store offline sales and stock edits on the shop device. When connection returns a background sync engine can send the queued records to the central database using timestamp based conflict resolution logic. I can implement WebSocket push channels to broadcast stock level edits and corresponding sales history to your dashboard screens in under two seconds. I can also write a load testing script in Python to simulate five hundred concurrent sales transactions and verify database sync stability. In a past project I developed an offline first retail inventory and point of sale sync system using Node js WebSockets and local SQLite data queues. 1) Which specific web or mobile frontend framework like React or Flutter is Dukandar currently running on? 2) Do you prefer hosting the central backend and database on a Linux VPS using Node js or leveraging Firebase Firestore for real time sync? 3) What conflict resolution strategy like last write wins or server timestamp preference matches your retail business rules? Thanks, Bharat

@arshig8

Hi, I’ve carefully gone through your requirements and can build the real-time, offline-first inventory system for Dukandar with live stock updates, sales history, automatic sync, conflict handling, and sub-2-second updates across connected devices. I’ll focus on a reliable database architecture, efficient listeners, WebSocket/push updates, offline queuing, and production-ready code with proper documentation. Do you already have the existing Dukandar codebase and database structure? Also, should the solution integrate with your current POS/scanning flow or be developed as a separate module? Let’s discuss the architecture and current setup in chat and proceed with the next steps. Best Regards, Arshiya

@thiagofoz87

Your requirement is essentially a distributed inventory synchronization problem with low-latency propagation and offline resilience. The critical part is not only updating stock in real time, but guaranteeing consistency when stores temporarily lose connectivity and later reconnect with pending transactions. I would approach this with an event-driven backend architecture using a lightweight synchronization layer between local store operations and the central inventory service. Each completed sale generates an immutable stock event containing SKU, delta, timestamp, terminal/store metadata, and sales reference. Connected clients receive updates through WebSocket or Firebase listeners with sub-2-second propagation on LAN conditions. For the offline-first behavior, local writes can be persisted in a queue/storage layer and replayed automatically when connectivity returns. Conflict handling would be deterministic and documented, including duplicate event protection and reconciliation logic for concurrent updates. The solution would include: - Real-time stock broadcasting service - SKU dashboard/API with current stock + recent sales history - Offline sync and retry mechanism - CSV export for 30-day sales history - Load validation for 500+ concurrent transactions - Deployment and operational documentation for your IT team From a technical perspective, I would recommend a stack based on Node.js or Kotlin/Spring Boot with PostgreSQL, Redis/pub-sub or WebSockets for live propagation, depending on your existing ecosystem and hosting preferences. I can deliver a production-ready implementation with clean structure, documentation, and test coverage focused on reliability under unstable network conditions.

@jaroslavcaprata

Hi, The important part here is making the inventory system reliable when connectivity disappears, not just broadcasting stock changes in real time. I’d design the feature as offline-first, with every sale recorded locally first and synchronized to the backend when connectivity returns. For the backend, I’d use a transactional database with stock movements and sales as separate records, so the current SKU quantity can always be derived and audited against the sales history. A real-time channel can then broadcast confirmed changes to connected devices without requiring manual refresh. For offline conflicts, I’d use deterministic synchronization rules and idempotent transaction IDs so the same sale cannot be applied twice. The dashboard/endpoint would expose the current stock alongside the latest sales affecting that SKU, while a server-side CSV export can handle the 30-day history efficiently. I’d also include a load test around the 500-concurrent-transaction requirement and document the sync and recovery behavior. One important question: does Dukandar already have a local database/storage layer and existing sale transaction IDs, or would the offline transaction and sync architecture need to be introduced as part of this work? Thanks, Jaroslav Caprata

@alluankit01

Hi, I can build the offline-first live stock update system for Dukandar with real-time inventory changes, sales-history tracking, local sync, conflict handling, and dashboard/API support. The best solution is to first review your current POS/inventory flow, SKU database, sale completion logic, offline storage needs, and deployment environment. Then I’ll design a backend with API/WebSocket updates, local write queue, cloud sync, conflict rules, and a dashboard showing Current Stock + recent sales history per SKU. I’m comfortable with Laravel/Node/Python backends, MySQL/PostgreSQL, WebSockets, offline-first sync, inventory systems, POS workflows, local-to-cloud data handling, conflict resolution, CSV export, API design, and performance testing. Deliverables will include: * Live stock update backend * API/WebSocket broadcast * Current stock per SKU * Sales history per SKU * Offline queue and sync logic * Conflict handling documentation * Dashboard or endpoint * 30-day CSV export * Test dataset/script for 500 transactions * Deployment guide * Clean documented code I’ll focus on reliable sub-2-second LAN updates, graceful offline operation, and clear stock-change history so managers and cashiers can always see accurate inventory with the sale record behind each change. Best regards Ankit
