MERN Stack Developer | Full-Stack Engineer with a Security-First Mindset
I build modern web/mobile apps that are clean, fast, and secure using the MERN stack, GraphQL, PostgreSQL, and RabbitMQ. My goal is to create developer-friendly APIs, scalable systems, and user-first experiences—all fortified with best-in-class security (2FA, RBAC, brute-force protection, and anomaly detection).
🧠 Learning never stops: I’m currently diving into n8n, message queues, and Shopify development to expand my automation and e-commerce skillset.
