iOS application for safety training in the petrochemical industry, built from scratch in Swift 5 and used by 20+ enterprise clients to certify employees in oil and gas safety standards.
Classroom Locstatt is the mobile arm of the Locstatt safety training platform, designed specifically for the petrochemical industry where compliance and reliability are non-negotiable. The app serves two distinct roles: employees access published safety courses and complete their certifications, while instructors control the session in real time from a desktop interface.
On the mobile side, I built offline course synchronisation using Realm DB so employees could access content without a stable connection, and integrated real-time Socket communication so instructor actions on the desktop, like advancing slides, were reflected instantly on every student device in the room. Built end-to-end in Swift 5 with UIKit, from mockup design in Sketch to App Store release, and deployed across 20+ enterprise clients in the oil and gas sector.
