As a mobile app developer and UI/UX designer, I specialize in crafting innovative Flutter and React Native apps for healthcare, eCommerce, and hospitality industries, delivering seamless cross-platform solutions for Android and iOS in 2025. With over 20 successful projects, I build AI-driven mobile apps with gesture-based navigation, dark mode, motion design, and inclusive UI/UX, ensuring responsive, secure, and user-centric experiences. My expertise in Kotlin, SwiftUI, and Figma, combined with cutting-edge trends like AR integration, blockchain security, and 5G optimization, empowers startups and businesses to achieve their digital goals. In healthcare, I develop telemedicine apps with EHR/EMR integration and remote patient monitoring, enhancing patient care and accessibility. My recent project, a Flutter-based telemedicine app, streamlined doctor-patient interactions with real-time data sync and voice UI, achieving a 30% increase in user engagement for a U.S. healthcare startup. I prioritize inclusive design, incorporating VoiceOver and adjustable text sizes to meet EAA 2025 accessibility standards, ensuring apps are usable by all, including users with disabilities. For eCommerce, I create AR-powered apps with biometric payments and personalized shopping experiences, leveraging beacon technology for proximity-based offers. A React Native eCommerce app I designed for a retail client integrated AR product previews and context-aware interfaces, boosting conversion rates by 25% through immersive 3D visualizations and micro-interaction animations. My focus on minimalistic UI/UX design, paired with blockchain for secure transactions, ensures trust and engagement in competitive markets. In hospitality, I build guest experience apps with beacon technology and motion design, enhancing user interactions through location-based notifications and adaptive themes. A recent Flutter app for a hotel chain integrated beacon-driven check-in and voice navigation, improving guest satisfaction by 40%. My designs emphasize neumorphism and gamified elements like progress bars, creating intuitive and engaging interfaces that align with 2025 trends. With a proven track record, I’ve delivered secure, scalable apps for startups and enterprises, using tools like Firebase, Jetpack Compose, and Figma to ensure high performance and trend-focused functionality. My cross-platform expertise in Flutter and React Native reduces development costs while maintaining near-native performance, as seen in apps for Shopify and Spotify-inspired projects. I incorporate predictive analytics and AI-driven personalization to tailor user journeys, from context-aware healthcare dashboards to eCommerce recommendation engines. As a freelance mobile app developer on Upwork, I’m committed to staying ahead of 2025 trends like 5G app optimization, blockchain security, and voice-enabled interfaces.

I'm a full-stack developer who helps small businesses automate their workflows and build custom web applications. Instead of just coding what you ask for, I dig into your business challenges first to identify the technical opportunities you might be missing. Having built applications from concept to deployment and helped scale a web platform from its initial launch to hundreds of active users across multiple franchise businesses, I now want to apply that experience to help small businesses punch above their weight with the right tech. Here's what I specialize in: - Custom Web & Mobile Applications: Client portals, inventory management systems, and customer-facing apps that streamline your operations and expand your digital offerings. - Business Process Automation: Eliminate repetitive tasks with custom scripts and integrations - from automated data entry to API connections between your existing tools. - Data Modernization: Transform your spreadsheet chaos into organized databases with real-time dashboards that give you actionable insights into your business performance. - AI Integration: Practical AI implementations that streamline workflows without enterprise-level complexity or cost - from custom LLM workflows to predictive analytics. For technology, I use a modern tools that let me build fast: React (or React Native), Tailwind, and PostgreSQL. I also like to use Python for AI development and automation. I start every project with understanding your actual business needs, not just your tech requirements. After a consultation to assess your challenges, I deliver a diagnostic report with actionable recommendations - whether that's custom development, existing tools, or alternative solutions. Only then do we decide together whether to move onto implementation. Small businesses don't need enterprise solutions - they need someone who understands their constraints and can deliver maximum impact quickly. I've learned what it takes to build something people actually want to use, from product-market fit to user experience considerations. Ready to discuss how technology can solve your business challenges? Let's start with a conversation about what's slowing your business down and explore solutions that actually fit your needs and budget.
