Who I am
Application Engineer and Full-Stack Web Developer with hands-on experience in React, Next.js, Node.js, Express, and MongoDB, specializing in system design, backend architecture, and production deployment. I deploy apps on Linux VPS environments and manage Nginx, SSL, PM2, and automated backups. A strong collaborator with a growth mindset and real-world DevOps exposure.
I enjoy owning features end-to-end: designing the API, building a clean UI on top of it, and putting it behind Nginx with SSL, PM2 and automated backups. Currently based in Dhaka, Bangladesh.
