Our core stack is Node.js, React.js, Next.js, and Express.js, with MongoDB or MySQL for data and React Native for mobile. We deploy on AWS, Google Cloud, or a well-configured VPS with Docker and CI/CD pipelines. AI work builds on foundation models such as OpenAI GPT and Google Gemini through their APIs, and payment integrations span Stripe, PayPal, JazzCash, and EasyPaisa.
