As the creator of Swiftify, a leading product for Apple developers, I have experience with all aspects of the product development lifecycle. I have been working on a SaaS website, mobile and desktop apps, and integrations with external systems. I am particularly interested in these types of projects: - iOS and macOS apps (iPhone, iPad, Apple Watch, Apple Vision Pro); - Backend development using .NET Core, ASP.NET MVC, and WCF; - Plugins for web browsers, Microsoft Office applications, IDEs, and GPTs; - Language parsers and transpilers based on ANTLR. In addition to building my startup, I have also had a variety of roles, from freelance software development to building a software company. I pay great attention to detail and write very well-structured and documented code. I am comfortable working solo, as part of a team, or managing a team of developers.

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 assistant (QA specialist). 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, sign a second NDA, or directly inform that I should completely avoid letting my assistant access your project data in any way during negotiation process. 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.
