👋 Hello! I'm a Senior Full-Stack and React Native Developer with 7+ years of experience shipping web and mobile products with AI integrations, clean architecture, and reliable production delivery — across healthcare, edtech, and social networking. My core stack includes React Native, Expo, React.js, Next.js, Node.js, TypeScript, JavaScript, Nest.js, Express.js, REST API, GraphQL, PostgreSQL, MySQL, MongoDB, Firebase, AWS, Docker, CI/CD pipelines, and AI/LLM integrations (OpenAI and others). I work across both mobile and web — building cross-platform mobile apps, web dashboards, admin panels, backend services, APIs, authentication systems, payment and subscription flows, notifications, and real-time features. My recent projects have involved microservice-based backend architectures, secure authentication, payment integrations, robust APIs, and CI/CD pipelines for App Store, Google Play, and web deployments. My expertise includes: 📱 React Native & Cross-Platform Mobile Development - React Native / Expo app development - iOS and Android apps from one codebase - App architecture and feature development - App Store / Google Play release support - Push notifications - Authentication flows - Subscriptions and in-app purchases - Performance optimization - Bug fixing and app maintenance ⚙️ Full-Stack Web & Backend Development - React.js / Next.js web applications - Node.js / Nest.js / Express.js backend development - REST API and GraphQL integrations - PostgreSQL, MySQL, MongoDB - Firebase and AWS services - Admin dashboards and SaaS platforms - CI/CD, Docker, and deployment support 🧩 Architecture & Product Engineering - Clean architecture - Domain-driven design - Microservices - Modular monoliths - Event-driven systems - Scalable API design - Code refactoring and legacy system improvements - Unit and integration testing 🧠 AI Integration & AI-Powered Development - Integrating OpenAI and other AI APIs into web and mobile applications - Building AI-powered features: content generation, intelligent assistants, document automation, personalized recommendations - Hands-on experience shipping AI features in production (healthcare and edtech domains) - Using AI tools in my own development workflow to ship faster — while keeping the same engineering standards and code quality My experience spans healthcare, edtech, and social networking — from AI-powered clinical documentation platforms with EHR integrations, to AI-driven learning apps for kids, to event-based social networking products. Across these projects, I've built real-time data synchronization, payment and subscription flows, authentication and SSO, web admin dashboards, and robust backend services. I focus on long-term product stability, performance, and practical business outcomes — building products that are easy to maintain, extend, and improve over time. Whether you're launching a new product, modernizing an existing one, or extending a complex system, I bring senior engineering, modern AI capabilities, and reliable end-to-end delivery. Let's build something reliable and scalable 🚀

I architect and deliver production enterprise systems with AI integration. Not prototypes — systems that run businesses daily. Current portfolio includes platforms processing 1,000+ daily operations across construction, healthcare, IT management, and fintech. I work either alone or with a small technical team, which means you get architect-level thinking with full-stack execution speed. WHAT I BUILD: Enterprise SaaS Platforms - Multi-tenant business platforms with role-based access, real-time dashboards, and complex data models - CRM, project management, estimating, and operational tools — built from scratch, deployed to production - 40+ data model schemas, handling multi-project workflows with thousands of daily transactions AI Integration (Practical, Not Hype) - Claude and GPT-4 integration into real business workflows — not chatbots, but systems that analyze data, extract documents, auto-populate fields, and surface actionable insights - AI-powered document processing: upload contracts, reports, financial documents → structured data extraction with 25+ field accuracy - RAG systems, multi-model orchestration, and AI copilots embedded across entire platforms Full Production Stack - Next.js / React / TypeScript frontends - Node.js and Python (FastAPI) backends - PostgreSQL and MongoDB databases (Prisma ORM) - AWS infrastructure (EC2, S3, RDS), Vercel deployment - Stripe, Gmail API, Zoho, and third-party API integrations - Authentication (NextAuth, Clerk, JWT), DLP, audit logging RECENT WORK: → Construction Management Platform (10 months, production) Quality control, field reporting, time cards, budget tracking, AI image analysis. Used daily by field teams across multiple projects. 99%+ uptime. Evolved through 3 major versions. → CRM & Estimating Platform (7 weeks, concept to production) Full CRM with 40+ fields per record, AI auto-populate from document upload, cost code analysis against historical data, import pipeline for legacy data migration. Delivered ahead of 12-week timeline. → IT Device Monitoring Dashboard Real-time health scoring across 1,000+ devices, 500+ organizations. AI anomaly detection for disk, RAM, OS patches, and antivirus coverage. → Enterprise AI Wrapper Multi-LLM access platform (Claude, GPT-4, Gemini) with user management, DLP scanning, usage analytics, and zero data retention policy. → Telemedicine Platform Doctor-patient consultation system with image upload, Stripe payments, GDPR-compliant AWS S3 storage. Built for EU market. WHY $90/HR IS A DISCOUNT: Each of these platforms would cost $150K-$500K with an agency. I deliver them as a technical lead with a small team, which means lower cost, faster iteration, and one person who understands the entire system — not a rotating cast of junior developers. I'm selective about projects. Best fit: businesses that need a real system built, not a landing page.

Your last developer ghosted you. The one before that delivered spaghetti code you're still paying someone to fix. And now you're scrolling through 200 profiles that all say the same thing: "I am a passionate full stack developer with 6+ years of experience." Stop. Read this instead. Here's what I've done recently: → Built an AI-powered wellness platform — zero to 500+ users in 3 weeks. Sentiment analysis, recommendation engine, intelligent chatbot. My client called the quality "exceptional" and me "a true partner." → Shipped a multi-tenant AI marketplace with LangChain automation for a US-based startup. The CTO called me "a highly skilled AI Senior Engineer." → Built a healthcare staffing platform with nurse registration, compliance tracking, client dashboards, and Stripe payments. The founder said he "had no clue how complicated it would be" — I handled everything. What I build: → AI-powered SaaS from architecture to production → LLM systems — chatbots with memory, RAG pipelines, AI agents that actually work → Stripe-integrated platforms — subscriptions, Connect, marketplace payment splits → Multi-tenant apps with RBAC, admin panels, and clean APIs → MVPs that don't look or feel like MVPs I am NOT the right developer for you if: ⛔ You're shopping for the cheapest rate on the platform ⛔ You want 15 revisions because you don't have a clear vision ⛔ You think "MVP" means broken and ugly ⛔ You've already burned through 3 developers and blame all of them I AM the right developer if: ✅ You're a founder or product owner with a real vision. ✅ You want one person who owns your entire product — frontend, backend, AI, infra, deployment ✅ You're tired of explaining the same thing to developers who still don't get it ✅ You want to launch in weeks, not months — without accumulating technical debt that kills you later Here's how this works: you message me with what you're building, your timeline, and your budget. I'll review it. If I can deliver something great, I'll respond within 4 hours with a clear plan. If I can't, I'll tell you why and point you in the right direction. I don't pitch. I don't beg. I build.
