Mohali, India

Professional Software Application Developer with over 6 year's of experience. Video and photo editing app expert. I am an experienced iOS software engineer, and I've been working in Swift since the day it was released. My primary focus is building iOS apps in Swift and Objective-C. I love nothing more than designing a good, solid foundation for an app and then building it up! Over 6 years experience in mobile application development including iOS and Android based native and cross platform mobile application development. The rich exposure across various industry verticals helped in polishing my skills in following areas 1. iOS Apps Development (iPad, iPhone), Objective C, Swift, Cocoa, XCode and Android Apps Development (mobile, tablets), Java, Kotlin. 2. Cross Platform application development using React Native. 3. Google Map API and development of Location based mobile apps. 4. Social Networking apps and their interaction with PHP/.NET based webservices. 5. Video/Audio streaming and editing apps. 6. Deep Integration of social media APIs such as Facebook, Linkedin, Google or Twitter etc. 7. Integration of the third party SDK such as GoogleAdmob, iAd, Adwhirl, Revmob, Urban Airship, Flurry, Google Analytics etc. 8. Push Notification by using APNS and C2DM. 9. In-App purchases. 10. NFC Tech (QR and Barcode scanning by using Zxing and RedLaiser) and MDM (Mobile Device Management). 11. Photo Sharing and Image Processing apps. 12. Network Communication and Database programming using SQLite. 13 ARkit based apps. 14 Sinch based video and audio call and messaging. 15 Firebase integration based apps. 16 Beacon integration of both iBeacon and eddystone using estimate. Also we worked on the broadcasting of beacons from phone as well. My iOS skills include: • Deep learning. Ever since Apple introduced CoreML, I've gotten quite skilled at training and efficiently implementing on-device neural networks to do all sorts of tasks such as image recognition, handwriting recognition, ARKit and so on. • Animation and design: From simple swipe-based animations to complex GPU accelerated animation. • Location Services: I have years of experience working with GPS data and Apple’s Location Services framework. • Maps: I have had 5+ years of experience with both Google’s Maps SDK and Apple’s MapKit. Mapping (cartography) is actually quite an interesting and extensive field, but it can also be really fun and rewarding. In one app I worked on called Doozyrama, I built a map with a tile-layer on top (like a fog), and whenever the user moved around the city it would clear out tiles to show where they went. It was quite a challenge to make it fast, and involved a lot of fundamental computer science techniques and efficient data structures. • Advanced computation techniques: Techniques such as SIMD, multi-threading, GPU acceleration, and smart data structures can do remarkable things when implemented right. This is often one of the areas where iOS developers tend to fail, because if an algorithm isn't designed and tested right, it can cripple an app. • Core Data, Realm: I have years of experience with Core Data, however in recent years I've started to greatly prefer using Realm DB instead. Core Data is quite old at this point and requires a ton of boilerplate code that can be difficult to maintain, Realm is significantly simpler and faster. • Security: This is often a highly overlooked factor, and it has never been more important. Simple security techniques such as HTTPS, secure password hashing, and encryption can be easily implemented to make an app secure. We always stay up to date to recent technologies across all the platforms. And always work with the latest versions of software to give the best experience to our clients.
