I'm an experienced and motivated Senior iOS Developer with an interest in skillfully crafting creative mobile applications and utilities. I understand the importance of creating highly readable, reusable and easily maintainable source code. I am constantly striving to learn new technologies and look to ways to better myself in this rapidly changing industry. I've got an NDA signed with a personal QA assistant. The idea behind - is to have a long-term personal assistant with lower rate helping to ensure the quality, shape the Test Cases, verify the recently developed features on various iOS versions and devices, doing additional manual regression testing, in some cases extra QA automation - to deliver even more reliable and consistent product, decreasing the final cost/dev-time for you, and letting me focus on the challenging things. According to your business processes - you can onboard my assistant too or keep me as a single contact person, or directly inform that I should completely avoid letting my assistant access your project data in any way during negotiation process (Unfortunately once there was a miscommunication about this - and one client got upset that I gave a build to my QA to verify the features developed, though the manager from his side knew about that). My strengths and skills: - 13 years of successful international IOS Development - Firebase (JS Cloud Functions) Development Expert - Computer Science Masters Degree - Project Management & TechLead skills - Software Architecture, REST API design skills - iOS Unit/UI Testing - iOS Continuous Integration (CI) using Jenkins, Fastlane, Xcode Cloud Completed a number of projects, while working at/through: 1) Sloboda-Studio (sloboda-studio.com) 2) NIX Solutions (nixsolutions.com) 3) Search Concepts AG (searchconcepts.ch) 4) TopTal (toptal.com) 5) Upwork 6) imito AG (imito.io) If according to your business goals you'll need web frontend (React JS), backend (Node.js) and Android development to be handled - I can help to manage that through a network of trusted partners.iPhone App Development

I have 11 years of experience working full-time as iOS/macOS development. You can see more about my experience in Employment History section. Short version: First half of my career was in outsource company Onix-Systems, where I worked on a lot of very different projects, estimated pre-sales, and lead the whole iOS department of the company. During that time I also made my own startup of a simple loan recording app Evenly, which was my main playground to learn some development/product/marketing topics deeper that I could while working main job. Then I moved to MacPaw which is a product company, where I've worked for 6 years in a product team. There I learned industry standards and state of the art approaches to full-cycle development of a product, marketing, working in a focused team, development processes, infrastructure etc. There I worked on such apps: Gemini Photos (now CleanMyPhone), Gemini 2, Swoosh Video Editor.iPhone App Development
