At ARJ Technologies, I developed and maintained production web applications with React.js and Next.js, alongside Android and iOS applications using React Native CLI. I also built and integrated Laravel/PHP and Node.js/Express REST APIs with MySQL for ERP, education, business, sales, and management platforms.
I developed features including authentication, role-based access, payments, notifications, and QR, barcode, and RFID workflows. My work covered development and API integration through testing, deployment, and maintenance on Linux/VPS production servers.
