    WatchKit, Swift, iOS, iPhone, Android, Mobile App Developer

    Pakistan - Tests: 6 - Portfolio: 41

    My experiences which span 8+ years in business and 14+ years with computers are focused on business analysis, software development and quality assurance. I pay more attention to the requirements analysis phase as this is the basis for the upcoming phases. Regarding my technical expertise, my core areas of interest include: ✔ Apple Watch Development / Watchkit framework ✔ Native Mobile Development: iOS (Objective-C, Swift) + Android (Java) ✔ Web service: XML/JSON, REST/SOAP ✔ Cloud backend: Parse.com, Parse SDK, Parse REST, Parse Cloud Code ✔ Backend with hosting server: PHP / MySql Having worked with a variety of technologies, I am capable to take care of both backend (server side development / web services) as well as front end of mobile apps. I program while taking care of all the principles of OOP (Object Oriented Programming) which boosts speed as well as performance. Major APIs I have worked on go here: ✔ Alchemy API ✔ Clickbank Payment API ✔ Link Point Central API ✔ Paypal Payment API ✔ Google Maps API ✔ Facebook / Twitter / LinkedIn ✔ Yahoo Web Search API ✔ Google SOAP Search API ✔ Plaxo Email Address Import etc. These skills have been exercised across several domains including: ✔ Social media ✔ Audio & Video Processing ✔ Location services ✔ eCommerce ✔ Fitness ✔ Travel ✔ Sentiment Analysis/Natural Language Processing ✔ Data Mining ✔ Real Estate and ✔ Inventory Management. I am here to assist small business owners utilize their full potential by offering consultation, analytical business insights and technical services which will increase profit margins and add value to the company brand. In one phrase, I help bring ideas into reality. I will work closely with you to know your exact business objectives thus laying out the set of requirements accordingly. Together, we will discuss them and brainstorm potential scenarios until we narrow the field to a working solution. I'll start actual development once the final set of specification gets agreed upon and signed by my client(s). This helps them to have a realistic estimate of the time and the budget involved to get their project finished. I have been fortunate enough to work with serious clients on oDesk who appreciate the value I was able to deliver them. Having long term partners has a lot more worth than getting just a job. I hope to continue this trend and look forward to contributing to like minded and successful business owners. Update (April 2, 2015): I am recently done with learning of Apple Watchkit required for the apps for Apple watch. I have an in depth understanding of how an app with a small display screen should interact with the user. I will get the actual Apple watch device by June 2015 through which I will be able to perform live testing of your watch apps. Whats the need of a watch app? Here it goes: - Your existing app notifications can easily show up on Apple Watch - Existing iPhone apps can be taken even further by extending and enhancing their functionality on Apple Watch - New ideas based on the unique capabilities of the apple watch can be implemented as this is the high time to penetrate in the market of watch apps.
