iOS Mobile Developer | Android & iOS | Cross-platform Flutter| BLE

I help healthcare companies and digital health teams build mobile apps faster, securely, and cost-efficiently, especially for connected devices, BLE integrations, and regulated environments. Instead of managing separate codebases, I deliver a single, scalable cross-platform architecture that supports medical-grade mobile applications, reduces development time by 40–60%, and maintains native performance. My focus goes beyond standard mobile development — I specialize in healthcare ecosystems, including: • Connected medical devices & wearables (BLE, IoT) • Real-time and near real-time health data processing • Apple Health / Google Fit integrations • HIPAA-aligned architectures & secure data handling • Remote patient monitoring & digital therapeutics apps Whether you're building an MVP or scaling an existing product, I help you choose the right architecture, avoid costly mistakes, and accelerate time to market.
