Dec 2022 - Present • 3 yrs 5 mos
Senior Mobile App Engineer specializing in Flutter development with proven AI integration expertise. I have built and launched 10+ production-ready applications currently serving active users on both App Store and Google Play across healthcare, FinTech, marketplace, and business management sectors. My AI-powered portfolio includes HealthiPlate (AI meal scoring with 30+ nutrient analysis), GetSimpple (AI-driven tax filing with OCR processing), and NOAH AI (GPT-powered assistant with document analysis). These demonstrate my capability to integrate OpenAI APIs, machine learning models, and natural language processing into user-friendly mobile interfaces. I specialize in cross-platform development using Flutter, delivering simultaneous iOS and Android deployment from single codebases while maintaining native-level performance. My technical stack includes Firebase (Authentication, Firestore, Cloud Functions, Storage), RESTful APIs, payment gateways (Stripe, Flutterwave, Paystack), real-time synchronization, and push notifications. My experience spans two-sided marketplaces (Omni Connects, Local Caregiver), multi-role enterprise platforms (Falke Facility Management, WorkBridge HRM), healthcare solutions (AskMed with HIPAA compliance), and booking systems with geolocation. I have implemented in-app subscriptions, OCR data extraction, barcode scanning, voice processing, gamification, and admin dashboards. I build scalable applications with clean architecture, state management (Riverpod, Provider, Bloc), and security-first approaches for sensitive data. My process emphasizes user experience, performance optimization, and production-quality code supporting long-term growth. I manage complete development lifecycles from concept to store deployment, including UI/UX implementation, backend setup, integrations, testing, and documentation.
