Led an Agile squad of 5 iOS developers with two-week sprints, enforcing code quality, documentation, and reviews. Built a feature-rich notes app using Swift, MVVM, UIKit, Core Data, and GCD with async/await. Integrated in-app purchases, rich text editing, and Firebase analytics tracking. Developed reusable TCP client communication framework TSFClient with secure two-way SSL using OpenSSL. Created TDBEngine framework as an alternative to CoreData for database management, ensuring data consistency offline and online. Modularized codebase using Swift Package Manager reducing build time by 50%. Applied strong design patterns and TDD reducing development time by 50%. Used Instruments to fix memory leaks and optimize performance.

Led a team of 5 iOS developers in an Agile environment, delivering a feature-rich notes application using Swift, MVVM architecture, and core Apple frameworks. Integrated in-app purchases, rich text editing, and analytics with Firebase. Developed reusable TCP communication and database frameworks to improve security and data integrity, optimized build times by modularizing the codebase, and applied test-driven development practices to reduce development time significantly. Addressed memory leaks and performance issues using Instruments.

Developed Cummins Guidanz™, a BLE-integrated iOS diagnostic app used by over 50,000 technicians globally. Collaborated in a cross-functional Agile team with product, QA, firmware, and backend stakeholders. Integrated RESTful APIs and C++ backend for real-time fault code resolution. Reduced crash rate to under 1.5% and enhanced CI/CD via Jenkins and TestFlight. Delivered multilingual support and designed features with MVVM, Core Data, and GCD to handle 1,000+ fault code types using INLINE™ adapter (J1939 protocol). Increased test coverage by 35%, reduced hotfix deployments by 60%.
