Senior Software Engineer with over 10 years of experience in software development. I have designed and developed backend services using JSP. I have also built numerous Android applications from scratch and distributed them on Google Play. For the past 8 years, I have been working with iOS using Objective-C and Swift. My experience in switching between platforms has given me a strong understanding of how backend works with both iOS and Android. Developed numerous iOS applications used by millions of users, assisted many companies in resolving application issues, and implementing new features. Also, overhauled and completely redesigned applications from scratch. Worked on various projects in domains such as food ordering, advertising, travel, auction, video and audio streaming, delivery, and sound apps. It takes 10 times longer to write code than to understand bad code, so I always strive to write clean and understandable code to make other developers' lives easier.
