We are launching an Electric Vehicle (EV) charging station business and are looking for an experienced full-stack development team or senior developer to build a complete EV Charging Management Ecosystem. The goal of this project is to build a user-facing mobile app (iOS & Android) and a robust backend Central Management System (CMS) that communicates seamlessly with our hardware chargers. Our chargers use standard OCPP 1.6J (with plans to migrate to OCPP 2.0.1), and the system must allow users to find, authenticate, activate, and pay for their charging sessions directly through the mobile application. Core Project Scope & Deliverables: 1. User Mobile App (iOS & Android - Flutter or React Native preferred) • User Onboarding: Quick signup via phone number (OTP), email, or social login. • Interactive Map (Google Maps API): Live status of nearby chargers (Available, In-Use, Out of Order), distance, navigation, and filter by connector types (CCS2, Type 2, AC/DC). • Charger Operations: Ability to scan a QR code on the physical charger to select a gun/connector and start/stop the charging session. • Live Session Tracking: Real-time dashboard showing charging speed (kW), energy consumed (kWh), elapsed time, and current cost during an active session. • Payment Gateway Integration: Integration with local payment methods (UPI, credit/debit cards, net banking, and an in-app prepaid wallet system). • Billing & History: Auto-generation of PDF invoices, charging history logs, and push notifications for session updates (e.g., "Charging Completed", "Battery at 80%"). 2. Backend & Central Management System (CMS Dashboard) • OCPP Gateway: A secure backend server to communicate with chargers via OCPP 1.6J/2.0.1 protocols (managing boot notifications, heartbeats, meter values, and remote start/stop commands). • Station Management: Admin dashboard to add/remove charging stations, track live telemetry, monitor uptime, and remotely reset hardware. • Tariff & Pricing Engine: Ability to set dynamic pricing (e.g., peak vs. off-peak hours, pricing per kWh, or flat time-based fees), and configure idle fees. • User & Analytics Management: Track total revenue, energy dispensed, active users, and export business reports. Required Technical Stack & Skills: • Mobile: Flutter / React Native (Cross-platform) • Backend: Node.js / Python (Django/FastAPI) / Go • Protocols: Deep knowledge of OCPP 1.6J / 2.0.1 and WebSocket communication is a strict mandatory requirement. • Database: PostgreSQL, MongoDB, or Redis (for real-time tracking). • Cloud Infrastructure: AWS / Google Cloud / Azure with robust security and scalability. What We Are Looking For in a Freelancer: • Prior, proven experience building an EV charging app or working with OCPP protocols. Please attach case studies, Github repos, or screenshots of past EV projects in your proposal. • A clean UI/UX designer or the ability to work with provided Figma designs. • Strong communication skills and a commitment to post-launch bug support.

EV charging platforms usually become challenging once charger hardware communication, real-time session tracking, payments, pricing logic, and mobile synchronization all need to stay reliable simultaneously. The important part is structuring the OCPP communication layer and backend state management properly from the beginning. For this kind of ecosystem, Flutter + a scalable Node.js backend would make a lot of sense because it keeps both the user experience and operational infrastructure maintainable long term. For charger communication and live tracking, we’d likely structure the system around: • WebSocket-based OCPP handling • centralized charger/session state management • async event processing • real-time telemetry pipelines • scalable payment & billing workflows • Redis-backed live session updates We can help with: • cross-platform EV charging apps • CMS/admin dashboards • QR-based charger activation • live charging session tracking • wallet/payment integration • tariff & pricing engine setup • analytics & reporting systems • scalable backend/cloud deployment One thing we’d specifically focus on is operational reliability making sure charger status, session billing, energy consumption, and payment states remain synchronized correctly even during unstable network or hardware conditions. Happy to discuss the architecture, OCPP handling approach, and rollout plan further over chat.

Hi Building an EV charging platform is much more than a standard mobile app — the key challenge is stable real-time communication between chargers, users, payments, and the CMS through OCPP protocols. That’s exactly the type of system I can help you build. I can help with: • iOS & Android mobile app (Flutter/React Native) • OCPP 1.6J backend & WebSocket communication • Live charger monitoring & remote start/stop • CMS dashboard for stations, pricing & analytics • Payment gateway & wallet integration • Real-time charging session tracking • Billing, invoices & push notifications Recommended stack: • Flutter • Node.js / FastAPI • PostgreSQL + Redis • AWS/GCP deployment I’ve worked on real-time systems, admin dashboards, payment integrations, and scalable backend architectures involving live data and WebSocket communication. Suggested milestones: 1. Architecture & OCPP Gateway 2. Mobile App Development 3. Charger Communication & CMS 4. Payments & Live Session Tracking 5. Testing & Deployment Estimated timeline: 10–16 weeks depending on hardware integration complexity. A few quick questions: • Which charger hardware/OCPP vendors are you using? • Do you already have testing firmware/environments available? • Will pricing vary by station or charger type? Post-launch maintenance and scaling support are also available. Regards, Abhishek

Building an EV charging ecosystem means solving real-time hardware communication, live session tracking, and seamless payments simultaneously, and that is exactly the kind of full-stack mobile challenge I can thrive on. With strong expertise in Flutter and React Native, I build cross-platform mobile apps that handle complex real-time data flows cleanly. My backend experience covers Node.js and Python with WebSocket-based architectures, which maps directly to OCPP 1.6J protocol requirements including boot notifications, heartbeats, meter values, and remote start/stop command handling. For your platform I will deliver: A Flutter mobile app with OTP/social login, Google Maps live charger status, QR-based session activation, real-time kW/kWh dashboard, UPI and wallet payment integration, PDF invoice generation, and push notifications. A robust CMS dashboard with the OCPP gateway, station telemetry, dynamic tariff engine for peak/off-peak pricing, idle fee configuration, and full analytics with exportable business reports. Cloud infrastructure on AWS or Azure with PostgreSQL for transactional data and Redis for real-time session state, built for scale from day one. I work with Figma designs or can contribute UI/UX direction, and I commit to post-launch bug support as part of the engagement. This is a technically deep project and I treat it with exactly that level of seriousness.

Hello, I can help you build a complete EV Charging Management Ecosystem including the mobile app and backend CMS. I have experience in building real-time systems, Flutter apps, and backend APIs with WebSocket-based communication, which aligns well with OCPP-based EV charging requirements. I can develop a cross-platform mobile app where users can locate charging stations on a live map, scan QR codes to start/stop charging sessions, track real-time charging data (kW, kWh, cost), and complete payments through integrated gateways including wallet support. The app will also include charging history, invoices, and push notifications for session updates. On the backend side, I can design a scalable CMS with OCPP 1.6J integration to manage chargers, handle real-time communication, monitor sessions, and control remote start/stop operations. The system will also support dynamic pricing, station management, analytics dashboards, and secure cloud deployment using AWS or similar infrastructure. I will ensure clean architecture, real-time performance, and scalability for future upgrade to OCPP 2.0.1.
