Experience

Apple

At Apple, I am part of the client team working on the Fitness+ app, building and maintaining the experience across iOS, iPadOS, tvOS, and watchOS.

• Served as the DRI from the client team for the effort to bring Apple Fitness+ to 28 new countries, launched in December 2025.
• Contributing to the server-side stack in addition to client development.

Apple

At Apple, I was a part of the HD Maps team, where I designed and developed a metrics tracking dashboard. It was an internal tool to be used by the team to track metrics generated by the teams automation processes. The dashboard

• was built for macOS, iOS and iPadOS
• was built using UIKit and SwiftUI
• used Swift Charts framework for Charts
• had data modelled using Protobuf.

Apart from the dashboard, I got to work on their automation and validation processes using C++. Additionally, I helped out with features and bug fixes in other internal iOS apps and Vapor backend applications.

Pratilipi

Pratilipi is one of the leading startups in India (backed by Tencent). I served as the lead iOS Developer for their flagship product, a novel reader app with 8 million+ users. My contributions significantly enhanced user experience and streamlined development processes. My main accomplishment during my tenure was the development of the new reader module. To improve the reading experience, we introduced vertical and horizontal reading modes, color modes, and customizable font sizes and line spacing. This led to an increase in completed reads by 7% (as of August 2023). Some of my other accomplishments include:

• Overhauling the app's analytics system to clean up event tracking, enabling the product team to gain better insights into user behavior.
• Introducing a custom font system mimicking Apple's UIFont.TextStyle.
• Keeping the app's crash rate below 1% by resolving critical bugs using Firebase Crashlytics.
• Adding introductory offers to in-app purchases and fixing flows to enhance user retention and monetization.
• Developing a Swift wrapper for UICollectionView to minimize redundancy, improve modularity, and reduce development time.
• Mentoring an intern, helping him transition into a full-time developer role.

SETabView

I developed SETabView, a customizable and visually appealing tab bar library for iOS and iPadOS, designed to add beautiful animations to your app’s tab bar. It offers a variety of animation types and supports customization of tab bar colors, icons, and selected indices. This library integrates easily with your project, using CocoaPods or Swift Package Manager. SETabView’s API mirrors that of UITabBarController for familiar functionality while allowing for dynamic tab management and smooth transitions. All animations are built using Core Animation.

Joyride Games

At Joyride Games (a Web3 Game development platform), I was involved in the development of an SDK that allowed third party developers to plug in their Unity Games and integrate them into Joyride's ecosystem of games. I got familiarized with Modular + MVVM + Clean Architecture and its pitfalls (cicular dependencies). The codebase had Objective-C, Swift and SwiftUI. I was also involved in

• Migrating in game currency to crypto (Rally Token).
• Migrating core legacy modules (with memory leaks) from Objective-C to Swift.

QuizBee

QuizBee is a knowledge-based real money gaming app. It offers an immersive experience for gamers to play and compete on quizzes and various theme-based challenges with a chance to win real money.

I was the sole iOS developer, and built the iOS app from scratch. I donned mutliple hats, taking care of the design, while developing algorithms for different parts of the quiz engine. I spent significant time brainstorming features with the founders to drive and increase revenue. The company shut down in 2023 and the app is no longer available.

ConstraintKit

I developed ConstraintKit, a lightweight, flexible Swift library that simplifies Auto Layout in UIKit with a declarative approach. It enhances code readability by abstracting NSLayoutConstraint complexities, making it easier to create and manage layout constraints. The library supports common edge pinning, safe area handling, centering, and advanced constraint configurations. With extensions for both UIView and UILayoutGuide, it offers a unified constraint management system. It integrates easily via Swift Package Manager, helping developers build cleaner, and more readable and maintainable layout code.

Beacon Buddy

I built Beacon Buddy, an essential tool for developers working with iBeacon technology. It allows users to simulate iBeacons by entering UUID, major, and minor values, making it easy to test and develop beacon-related apps without actual hardware. The app also supports ranging and monitoring for iBeacons, and users can organize beacon configurations into folders for easy access. Ideal for speeding up development, Beacon Buddy simplifies the process of working with beacons by providing a user-friendly interface for testing and saving beacon data.

My Website

I built this website by taking a template and customizing it by adding and modifying HTML, CSS and JavaScript. I used Vapor (Server Side Swift) to build the backend. I used Leaf, Vapor's templating engine to render the HTML pages. I used Fluent, Vapor's ORM to interact with the database.

Freelancer

As a freelancer, I built 4 applications.

• Designed and developed the official application of MPBlitz, the interschool fest of M.P.Birla F.H.S. School, Kolkata.
• Developed ADG-VIT, the official app of ADG, a student club in VIT Vellore.
• Developed WalkIN Vellore, a comprehensive local guide to Vellore, Tamil Nadu. I built the backend intially using PHP and MySQL, but later migrated to Firebase.
• Developed the official application of Rivera, 2016, the cultural fest of VIT, Vellore. Used Firebase for backend.
