Backend implemented with Go and integrated with paypal gateway, MySQL is used as main database. • Collector implementation (architecture, planning and development). Collector service collects, analyzes information sent from devices via MQTT protocol and is responsible for communication between cloud services and devices. Completely re-implemented old deprecated collector service written in python as old implementations struggled with big load. New collector implemented with Go and supports bigger quantities of devices. • Client statistics (planning). Collector module responsible for clients statistics. Tracks user session counters, connection-start event and disconnection events. Module implemented with Go language, data stored in ArangoDB (NoSQL) database. • Proximity service (architecture and planning). Store and analyze information sent by devices and proxy all data to third party services. Main requirements was easy scalability and ability to maintain high load. Backend implemented with Go and allows 3rd party HTTP integrations. Redis is used as main cache service. • Guest Access (architecture and planning). Platform to implement and use captive portals where clients can login with social logins or voucher codes or simple username/password credentials instead of WPA-PSK key. Backend implemented with Go language, RADIUS (with MySQL extension) to store and verify credentials, MQTT to communicate with devices.
