With the ever-evolving world of mobile app development, you need a freelancer who can not only keep up but stay ahead. I bring to the table more than a decade of experience in the IT industry, including extensive knowledge and skill in both Android (Java/XML) and iOS (Swift/Core Data/XCODE). I have expert-level familiarity with all the technologies listed in your project description, including robust databases such as SQLite and MySQL – critical for an app of this nature. My long-standing history in technology plus hands-on exposure in using IDEs like Android Studio and Xcode testify my skillfulness. Aside from mere maintenance, my team and I have deep experience posting apps on both platforms which guarantees bug-free uploads to the App Store and Google Play Store every single time. I've also worked with similar analytics systems like Stripe, PayPal, Twilio so ensuring uninterrupted delivery on these features will be second nature to me. Availability is another area of strength. I'm able to provide around-the-clock communication support and take care of any unforeseen problems promptly with supreme ease thanks to my strong troubleshooting skills. Engagement with me isn't just about getting the job done, but building a holistic working relationship that exceeds expectations. Let's craft an unmatched platform for your users; my availability on a month-to-month basis at a competitive rate feels perfect to move forward. Best, DK
