Platform Architecture Overview
QWIKO is built on a layered, microservices-inspired architecture ensuring scalability, maintainability, and rapid feature delivery. The platform connects homeowners, service professionals, and administrators through a unified digital backbone.
How a Booking Flows Through the System
From homeowner request to job completion, every interaction passes through defined service boundaries with full auditability.
Core Platform Modules
Each module is independently deployable and communicates over well-defined REST/gRPC APIs and async message queues.
Manages the full lifecycle of a service request — creation, assignment, status transitions, cancellations, and rescheduling with conflict resolution.
Geo-spatial search across service professionals filtered by skill, availability, rating, and distance. Uses PostGIS and Elasticsearch for sub-100ms results.
Handles payment collection, escrow holding, automatic release on job completion, refund workflows, and automated payouts to service professionals.
Unified notification dispatching via push (FCM/APNS), SMS (Exotel/Twilio), and email (SendGrid). Event-driven triggers through message queue.
Real-time operational metrics and business intelligence — booking conversion funnels, pro utilisation, revenue analytics, and SLA monitoring.
KYC verification for professionals, fraud detection on transactions, dispute resolution workflows, and community reporting mechanisms.
