Technical Leadership

• Lead the end‑to‑end design, development, and optimization of advanced iOS applications using Swift 6 and SwiftUI 3.0.
• Establish and promote scalable architectural patterns such as MVVM, Coordinator, Clean Architecture, and modular feature development.
• Evaluate and integrate emerging Apple technologies including Core ML, Vision, ARKit 6, and RealityKit.

Development & Delivery

• Translate business and product requirements into well‑architected technical solutions.
• Drive consistent implementation of best practices in coding, performance optimization, and maintainability.
• Integrate modern backend APIs using async/await, robust networking, and secure authentication flows.

Quality, Testing & DevOps

• Ensure high code quality through structured code reviews and architectural guidance.
• Advocate and contribute to automated CI/CD workflows (Xcode Cloud / GitHub / GitLab) and enforce quality gates.
• Develop and maintain a strong test automation suite including unit, UI, snapshot, and performance tests.

Performance & Monitoring

• Use Xcode’s advanced debugging and profiling tools to identify, diagnose, and optimize issues related to concurrency, memory management, and UI rendering performance.
• Implement monitoring, analytics, and crash diagnostics to ensure app stability at scale.

AI/ML & Emerging Technologies

• Build intelligent features leveraging Core ML, Create ML, and on-device inference for personalization and predictive experiences.
• Experiment with spatial computing, ARKit, and LiDAR-driven experiences to support next-generation use cases.

Collaboration & Mentorship

• Collaborate with product managers, designers, and backend engineers to ensure cohesive product development.
• Mentor and support junior engineers, providing guidance on architecture, coding patterns, and engineering best practices.
• Foster a culture of continuous learning, innovation, and engineering excellence.

• Deep proficiency in Swift 6 including modern concurrency, safety enhancements, and performance improvements.
• Strong experience with SwiftUI 3.0+, declarative UI building, advanced layouts, animations, and multi‑device support.
• Solid knowledge of UIKit for handling legacy or complex UI flows alongside SwiftUI.
• Expertise in architectural patterns (MVVM, Coordinator, Clean Architecture) and modular design principles.
• Strong experience integrating REST/GraphQL APIs with modern async networking patterns.

Frameworks & Tools

• Hands-on experience with Apple frameworks such as Core ML, Vision, ARKit 6, RealityKit, Combine, and Core Animation.
• Proficiency using Xcode’s latest debugging tools, Instruments, and enhanced IDE features (Xcode 15/16).
• Experience with CI/CD pipelines, version control, automated testing, and App Store deployment best practices.

Leadership & Communication

• Strong technical decision-making and ability to influence architectural direction.
• Excellent communication skills for cross-functional collaboration and technical documentation.
• Ability to mentor, coach, and raise the technical bar for the team.

Mindset

• Passion for continuous learning, staying updated with iOS ecosystem advancements (iOS 18+).
