    Geoff Hackworth

    Experienced iPhone/iPad/Watch Software Engineer (Native Apps)

    United Kingdom - Last active: 10 days ago - Tests: 17 - Portfolio: 15

    I am a highly-skilled software engineer and computer science graduate with 23 years of professional experience. Software development is my greatest skill and I have an incredible attention to detail and perseverance in getting the job done, and done well. I've been developing native Objective-C iOS apps for over 3 years. I don't use tools like PhoneGap or Appcelerator. I have direct experience with Apple's policies, device capabilities and account management procedures from publishing my own apps (see my portfolio for screenshots and iTunes links). By hiring me you would benefit from my extensive skills and experience. Technologies change, but first-class analysis, design, development, testing and debugging skills can only be built from many years of hard work and real-life development experience. I work from home in a distraction-free environment using a Mac with dual 23" monitors. For good test coverage I own several iOS devices: iPhone 4S, iPhone 5, iPhone 5s, 1st generation iPad, 3rd generation iPad, retina iPad mini, iPad Air 2 and 42mm Apple Watch. I don't believe you can get the true "feel" of an app by just using the simulator. For client testing, I can use TestFlight to deliver builds throughout the project. Thanks for taking the time to read my profile. I'm looking forward to working with high-quality product designers and creating some great apps together.
