With 7+ years of experience building, scaling, and debugging mobile apps, I help startups and businesses turn app concepts into production-ready software, or step directly into existing codebases to ship new features, optimize performance, and finalize AI-generated builds into production-grade apps. How I Can Help Your Project: • Greenfield Mobile Development: Building native Android or Flutter apps from scratch, complete with scalable backend infrastructure (Firebase / Cloud APIs) and seamless publishing to the Google Play Store and Apple App Store. • Existing App Enhancements & AI Cleanups: Joining active codebases to add complex features, redesign UIs, integrate third-party APIs, or take over and stabilize AI-generated prototype apps, turning raw code into a robust, app store-ready build ready for submission and release. • Full Mobile Infrastructure: Setting up web admin panels, databases, and payment integrations so your app operates seamlessly end-to-end. Proven Experience Across Industries: • Health & Medical: Doctor appointment booking & medical analysis tools • Hardware & IoT: Real-time drone control and tracking applications • E-Commerce & On-Demand: Food ordering, coupon sharing, ride-sharing, and inventory management systems • Media & Utilities: Business networking apps, short-form video streaming, and custom VPN platforms Core Technical Expertise: • Mobile: Kotlin, Java, Flutter, Dart, React Native • Backend & Cloud: Firebase, Node.js, REST, WebSockets • Integrations & AI: OpenAI/LLM multimodal API integrations, Stripe, PayPal, Google Maps API, Geolocation/GPS, Push Notifications Ready to discuss your project scope or get a technical review?
