Senior Mobile Developer at Tech Mahindra

August 1, 2022 - August 1, 2024

Delivered production iOS applications in Swift, SwiftUI, MVVM, and Clean Architecture, driving technical design decisions and ensuring scalable, maintainable codebases across multiple enterprise client products. Owned the full App Store delivery lifecycle including certificate management, signing, provisioning, and coordinating releases across multiple build environments. Integrated third-party SDKs and RESTful APIs, including payment gateways and real-time data feeds, ensuring secure, reliable, and performant data flows in production. Mentored iOS engineers and established coding standards and code-review practices that reduced technical debt and improved consistency across multiple codebases. Used AI-assisted development workflows (Claude Code / Cursor) to accelerate refactoring, debugging, and automated test generation with mandatory human review.

iOS Engineer at Volansys Technologies

September 1, 2017 - August 1, 2022

Architected and delivered three production iOS applications from a single shared Swift codebase using a modular, multi-target architecture to enable significant code reuse. Designed data-flow architecture across networking, persistence, and presentation layers using REST and WebSocket transports, Codable models, and Combine pipelines with retry/reconnection and background-state handling. Built BLE and Wi-Fi communication layers for IoT hardware, including custom protocol handling and reconnection logic for field-deployed sensor systems. Implemented security-critical features including LocalAuthentication (Face ID / Touch ID), Keychain-backed credential storage, and encryption integrations for regulated production apps. Led performance profiling using Instruments and Memory Graph Debugger, resolving leaks/retain cycles and CPU bottlenecks; added deinit-level memory checks to CI to prevent regressions.

iOS Developer at Openxcell Technolabs

May 1, 2013 - August 1, 2017

Built and shipped multiple iOS applications in Swift and Objective-C across consumer and SMB products, developing strong fluency in memory management, app lifecycle, Auto Layout, and the Xcode toolchain. Migrated legacy Objective-C codebases to Swift and delivered interactive UIs with Core Animation and MapKit to improve type safety, maintainability, and responsiveness. Collaborated in cross-functional Agile teams through code reviews and developed systematic root-cause analysis practices for complex crashes and memory issues.
