Plenty of apps look great in a demo, then fall over the moment real users and traffic arrive. I build full-stack Node.js SaaS platforms with React, Next.js, and clean APIs, engineered to hold up when it counts. I've spent 7+ years building and leading production software across travel, fintech, healthcare, and real estate. One I'm proud of: I worked on SastaTicket, one of Pakistan's largest online travel-booking platforms, building flight and hotel booking with live Galileo GDS integration, payments, and SMS/email notifications on a Node.js and React stack serving a high daily volume of users. On the backend I work in Node.js, Express, and TypeScript to design clean, scalable REST and GraphQL APIs and microservices. On the frontend, React and Next.js for fast, responsive interfaces. I've shipped across web, mobile (React Native), and desktop, and I deploy on AWS and Azure with Docker and CI/CD so what I build stays reliable as it grows. A few products I've led or built: SastaTicket: high-traffic travel-booking platform with flight/hotel search, GDS integration, payments, and notifications. (Node.js, Python/Django, React, Redis, GCP) Waybase: web and mobile platform on a clean Node.js/Express microservices architecture. (Postgres, Redis, GraphQL, React, React Native, Azure, Docker) Carma Project: vehicle safety-recall platform solving a real problem, since 40 to 50% of recall notices never reach owners due to outdated addresses. (Node.js, Python, Angular, AWS) Homepie: real-estate SaaS with Stripe payments and DocuSign e-signing. (Node.js, React, Postgres, AWS) Code Tribe: online coding-education platform. (Node.js, Express, GraphQL, Postgres, React) I'm also actively expanding into AI integration, connecting LLMs like OpenAI's GPT and Claude into applications and building practical AI features like chatbots into existing products. If your project blends solid full-stack engineering with smart AI functionality, that's exactly where I like to work. Tell me what you're building and what "done" looks like for you, and I'll tell you straight how I'd approach it.
