Designed and built the Veel iOS app from scratch using modular architecture, improving team velocity and scalability. Architected a cross-platform video editing SDK (SwiftUI + Metal) enabling real-time 4K processing and reduced partner integration time by 40%, while leading offline-first sync and TDD/CI/CD practices.

Architected a secure fintech platform using certificate-based mutual TLS and end-to-end CryptoKit encryption, reducing fraud risk by 20%. Improved transaction success rate by 35% through payment workflow optimization and test coverage, and built reusable internal SDKs adopted across multiple products.

Redesigned streaming architecture to support 500K+ concurrent users using adaptive bitrate streaming and multi-layer caching, improving video load time by 90%. Reduced app cold-start time from 3.2s to 1.4s via Instruments profiling and automated CI/CD and XCUITest regression, cutting deployment cycle time by 30%.

Led iOS development of a high-traffic consumer app (1M+ downloads) and implemented Core ML features for on-device product recognition and smart pricing. Reduced video processing time by 90% using Instruments-guided optimization and a Metal GPU pipeline, while integrating secure payments, real-time maps, and push notifications with 75%+ XCTest code coverage.

Built and shipped core fitness tracking modules in Swift/UIKit and integrated HealthKit with real-time activity sync. Improved App Store rating from 3.8 to 4.5 by identifying and resolving crash hotspots using Instruments and Crashlytics.

Built and shipped 6+ production iOS apps in Objective-C and Swift across digital document signing, workflow automation, and fintech domains. Developed expertise in UIKit, Core Data, REST API integration, PDF rendering, and App Store submission workflows.

Earned a B.E. in Computer Science from Acharya Institute of Technology (VTU, Bengaluru), graduating in May 2013.
