Stage 01Discovery & Project Scoping
Stakeholder interviews to understand operational reality, typical event size, attendee types, ticketing model, exhibitor management requirements, and integration needs. Competitor teardowns across ticketing platforms (Eventbrite, Ticketmaster) and engagement platforms (Whova, Cvent, Bizzabo). Deliverable: discovery document, prioritized feature list, locked Phase 1 scope.
Stage 02Requirement Analysis & Documentation
User stories and acceptance criteria for every workflow across attendee, organizer, exhibitor, sponsor, and admin roles. User flow diagrams for discovery, registration, ticket booking, check-in, in-event engagement, and post-event follow-up. Data flow diagrams for ticket lifecycle, payment processing, and integration adapters.
Stage 03UX/UI Design
Information architecture, wireframes, interactive prototypes, and a full design system in Figma using Blue Lotus typography. Designed for four primary personas: the attendee discovering and booking tickets, the organizer managing the event, the exhibitor capturing leads, and the admin running operations. Distinct visual treatments for each user type while maintaining a consistent shared design language.
Stage 04Architecture & Technical Planning
System design covering Flutter state management, web frontend (React.js + Next.js) architecture, Node.js backend API contracts, real-time engagement engine (Firebase), payment processor integration, and AWS infrastructure topology. Database schema for events, attendees, tickets, exhibitors, sponsors, payments, and analytics.
Stage 05Mobile App Development
Flutter build for iOS and Android, single codebase with platform channels for native QR scanning, push notifications, and biometric authentication. Two app experiences, the attendee app and the organizer app, share the underlying SDK but have distinct UX flows.
Stage 06Web Frontend Development (Parallel)
React.js and Next.js web platform with server-side rendering for SEO-critical event discovery pages. Component library aligned to the design system. Three interfaces: public event browsing, exhibitor portal, and admin dashboard.
Stage 07Backend & API Integration Development
Node.js backend with adapter modules for payment processing, email marketing platforms, CRM systems, and analytics tools. RESTful APIs with Swagger documentation. Real-time engagement pipeline using Firebase for live polls, Q&A, and messaging.
Stage 08Quality Assurance & Device Testing
Functional testing across 20+ device profiles covering iOS and Android, desktop browsers, and varying network conditions. End-to-end testing of registration, payment, check-in, and in-event engagement flows, including failure scenarios (payment decline, network drops mid-registration, concurrent ticket purchases for the last available seat). Independent security review against OWASP Mobile Top 10 and PCI-DSS requirements.
Stage 09Launch & App Store Submission
Phased rollout: web admin panel launched first for organizer onboarding, then iOS and Android apps submitted to App Store and Google Play. ASO optimization for both stores. Privacy policy review for GDPR compliance.
Stage 10Post-Launch Support & Iteration
2-week sprint cadence for performance fixes, UI refinements, and feature additions based on event organizer feedback and attendee usage patterns. Critical bugs are fixed within 24 hours, high-priority bugs within 72 hours. Quarterly performance reviews covering ticket sales conversion, check-in rates, engagement metrics, and exhibitor satisfaction.
