Vakul M.

I am Vakul, a Senior Mobile & AI Lead Developer with 9+ years of experience designing, building, and scaling production-grade mobile applications across healthcare, fintech, IoT, SaaS, marketplaces, EdTech, and AI. I don’t approach mobile development as simply building screens. I focus on the complete product architecture mobile applications, APIs, backend services, real-time communication, device integrations, security, AI capabilities, offline synchronization, testing, CI/CD, and production operations. I have extensive experience leading mobile development from requirements and architecture through implementation, code reviews, optimization, release management, and production support. AI & AI-Native Development - I have increasingly focused on AI-powered and AI-native application development, integrating intelligent capabilities into real products rather than building isolated AI demos. My experience includes: OpenAI / GPT API integrations Anthropic / Claude API LLaMA and open-source LLMs RAG and knowledge-based AI systems AI assistants, AI-powered search and recommendations Embeddings and vector databases Function/tool calling Structured LLM outputs AI memory and contextual personalization Document understanding and extraction AI-powered workflow automation Agentic workflows and tool-using AI Prompt engineering and response evaluation AI integration into existing mobile applications I also work with modern AI-native development tools, including Claude Code, Cursor, ChatGPT, Codex, GitHub Copilot, and Replit. I use these tools throughout the engineering lifecycle for architecture exploration, rapid prototyping, code generation, refactoring, debugging, test creation, documentation, code review, API development, and performance optimization. The goal is to combine AI-assisted development with strong engineering fundamentals to ship faster while maintaining maintainability, security, scalability, and code quality. I specialize in: Mobile architecture and scalable application design React Native and Flutter cross-platform development Native Android development with Kotlin Complex navigation and state management REST / GraphQL API integration Real-time applications and live updates Push notifications and background processing Offline-first architecture and synchronization BLE and IoT device integration Wearables and healthcare devices GPS, camera and native device capabilities Biometric authentication Payment and subscription systems App performance optimization Crash monitoring and production debugging Secure authentication and data handling CI/CD and automated releases App Store and Google Play deployment OTA updates and release management Technology Stack- Mobile: React Native, Flutter, Kotlin, Android SDK Languages: TypeScript, JavaScript, Dart, Kotlin State Management: Redux Backend/API: REST, GraphQL, Firebase, Node.js Databases: SQLite, Realm, PostgreSQL, Firebase Cloud: AWS, Firebase, AWS S3 AI: OpenAI, Claude, LLaMA, RAG, Vector Search, AI Agents Automation: n8n, APIs, Webhooks, workflow automation Authentication: Firebase Auth, Apple Sign-In, Social Login, Biometrics Payments: Stripe, Razorpay, Apple Pay, In-App Purchases CI/CD: Fastlane, Codemagic, GitHub Actions, GitLab CI/CD, CodePush AI Development: Claude Code, Cursor, ChatGPT, Codex, GitHub Copilot, Replit Tools: VS Code, Android Studio, Xcode, GitHub, GitLab, Bitbucket Healthcare & Connected Health - Built production healthcare applications supporting patient engagement, CCM, RPM, RTM and BHI workflows. Experience includes BLE medical devices, wearable integrations, real-time vitals collection, background synchronization, alerts, patient workflows, provider dashboards, secure authentication and structured healthcare data. I have also integrated AI capabilities to support contextual assistance, personalization and workflow automation. Fintech & Payments - Developed mobile applications for payments, subscriptions, lending and financial workflows, including payment gateway integrations, secure authentication, transaction processing, subscription lifecycle management and real-time status updates. IoT & BLE Applications - Built mobile applications communicating with BLE devices, wearables, sensors and connected hardware, including device pairing, background communication, data synchronization, connectivity recovery and real-time data processing. AI-Powered Applications - Built AI-enabled applications using OpenAI, Claude and LLaMA, including conversational assistants, RAG pipelines, contextual search, personalized responses and workflows. SaaS, ERP & POS Applications.- Developed mobile applications for inventory, orders, purchasing, field operations and multi-location businesses, with real-time synchronization between mobile users and backend systems. AI-Powered Mobile Applications Integrated OpenAI, LLaMA & RAG-based systems into mobile applications to provide contextual AI assistants, intelligent search AI-driven workflows.
