Jagveer Singh

I've delivered 10+ mobile apps across logistics, fleet, and B2B domains, from initial development through App Store and TestFlight deployment. At Instant Supply Chain Solutions, I lead development of an enterprise iOS application for order booking, real-time inventory tracking, vendor management, and automated alerts.

I reduced manual operational errors by 50% by automating key enterprise workflows and built offline-first synchronization for reliable use without connectivity. I also implemented Keychain-based secure storage, certificate pinning, multi-environment builds, and CI/CD pipelines with Fastlane and Azure DevOps.

I've shipped a production AI chat assistant using the OpenAI GPT API, including streaming responses, conversation context, and retry handling. I also built on-device face detection and photo capture validation with Vision Framework and AVFoundation, avoiding server-side image processing.

My work spans Swift, SwiftUI, UIKit, Objective-C, Flutter, scalable mobile architecture, performance optimization, and secure production delivery. I've also built vehicle tracking, driver, vendor, customer, inventory, compliance, and logistics analytics products.
