What I'm looking for

I’m seeking an opportunity to contribute as a full-stack developer while advancing my professional growth, building secure, user-centered products with React, Node.js, MongoDB, and Postgres.

At GeeksSort, I enhanced and maintained full-stack applications using React.js, Next.js, Nest.js, and Express.js. I improved API response times by optimizing database queries and middleware structure.

I also managed deployment and monitoring of live applications on Hostinger and Contabo. As a Software Engineer Intern at GeeksSort, I improved and debugged full-stack features used by real clients.

In my RealEstate project, I developed a platform with a NestJS REST API, Prisma, and PostgreSQL, along with a secure JWT-based admin dashboard for managing website content. I also integrated Cloudinary for image uploads and content management.

My other projects include a restaurant management system with Stripe payments and Firebase authentication, a digital wallet with SSLCommerz payments, and a tour booking platform with password and Google OAuth authentication. I work with React, Node.js, and databases including PostgreSQL and MongoDB.
