🚀 Are you building a mobile app and need someone who can take it from idea ➡️ App Store / Google Play release (and then keep improving it)? Or do you already have an app and want to ship features faster, fix bugs, improve performance, or refactor for scalability? I help startups and product teams deliver iOS + Android apps with clean architecture, predictable delivery, and clear communication - across native and cross-platform solutions, depending on what fits your timeline and budget. I also use AI-assisted coding to speed up routine work (boilerplate, refactors, tests) while keeping quality high through solid structure, reviews, and real-world testing. Here are some of the results my clients are getting: ✅ “Nataliia delivered professional code recommendations, improving the quality of my codebase. Very recommended.” ✅ “Amazing dev” ✅ “Smart, Autopilot, Great communication.” ✅ “Nataliia did a great job in a short time. Very capable iOS developer.” ✅ “Quickly and with high-quality coding. Nataliia is very recommended.” Industries I often work with: mental health and wellness, digital health, social networking/community platforms, sports & fitness tracking, chat-first products (coaching/companions/support), habit & productivity apps, and subscription-based consumer apps. Working with me, you will get a developer who can: 👍 deliver a bug-free and smoothly-running app that can boost your business or bring your idea to life on time 👍 take your project from idea to successful launch 👍 take ownership of the project and deliver it on time 👍 review the code, and improve it. 👍 work with your team and other stakeholders to deliver a great product How I work: 📌 Clear milestones + weekly progress updates 📌 Strong focus on stability, UX accuracy (design → app), and maintainability 📌 Ownership mindset: I flag risks early and propose options, not problems My background in numbers: 📊 8+ years in mobile development 📊 35+ projects shipped & supported 📊 100% Job Success Rate on Upwork 📊 Typical MVP first build: 3–6 weeks (scope-dependent) SOUND LIKE A FIT?
