MERN Stack Developer for Dashboard Setup & Subscription Module.
Working with Harendra was a great experience. He quickly set up a MERN stack dashboard connected to my existing database and implemented a smooth subscription module. The entire workflow was clean, efficient, and exactly what I needed. His knowledge of MongoDB, Express, React, and Node.js is solid, and he delivered within the agreed budget and timeline. Highly recommended for anyone looking for a reliable MERN stack developer to build dashboards or subscription-based features.
