About Kundan
Full Stack Developer - React Native, Node.js, Next.js, AI and DevOps

Job Success
Mohali, India - 10:43 pm local time
Most clients need 3 to 4 different freelancers to build a complete product - a mobile dev, a backend dev, a web dev, and someone for deployment. I do all of it, solo, from one codebase to production.
📱 Mobile - React Native
Cross-platform iOS and Android apps. Firebase, Supabase, Stripe payments, push notifications, real-time features. Single codebase, both platforms, shipped on time.
🌐 Web - NextJS and ReactJS
Server-side rendered web apps with TypeScript, SEO optimization, and clean component architecture. Figma to production ready.
⚙️ Backend - NodeJS and Express
REST APIs, OpenAI and Gemini AI integration, MongoDB, PostgreSQL, Supabase, AWS. Backends built to scale from day one.
🚀 DevOps and Deployment
Docker, CI/CD pipelines, AWS, Heroku, App Store and Play Store publishing. I do not just build. I deploy and maintain.
🤖 AI Integration
OpenAI API, Gemini - chatbots, automation workflows, real-time AI responses built into your product.
Industries I have built for:
💰 FinTech - payment apps, digital wallets, banking dashboards, Stripe integration, transaction tracking and financial reporting systems.
🛒 eCommerce - full shopping platforms with cart, orders, product management, payment gateways and real-time inventory systems.
🏥 HealthTech - fitness tracking apps, medical appointment booking, wellness platforms, health data dashboards and push notification reminders.
🏠 Real Estate - property listing apps, booking and scheduling systems, map integrations, agent dashboards and lead management platforms.
📊 SaaS - admin panels, multi-tenant dashboards, subscription billing, role-based access control and analytics platforms.
🎓 EdTech - online learning apps, course management systems, video streaming, progress tracking and student dashboards.
🤖 AI Apps - OpenAI and Gemini powered chatbots, automation workflows, AI content generation, smart search and real-time AI response systems built into mobile and web products.
💬 Social and Community - real-time chat apps with Socket IO, community platforms, social feeds, user profiles, notifications and dating app features.
Whether you need an MVP shipped in 2 weeks, a full production system with DevOps setup, or AI integrated into your existing product - I have built it across all these industries. Just message me with your idea and I will tell you exactly how I would build it.
I write clean, documented code. I communicate daily. I do not disappear after delivery.
Stack: React Native, NodeJS, NextJS, ReactJS, TypeScript, Firebase, Supabase, MongoDB, PostgreSQL, OpenAI API, Express, AWS, Docker, Heroku, CI/CD, Socket IO
