Node.js Developer to maintain & enhance existing AWS-hostedv application

We have an existing Node.js / JavaScript web application running on AWS (cloud server). The app connects to a product database and provides a web interface where users select product codes/SKUs. The system loads product data (photos, prices, specs etc) and generates quotations using standard templates. Users can edit or add products, fill a few additional fields in the UI and then export the quotation to PDF and Excel. We’re looking for an experienced Node.js developer to take over maintenance and implement enhancements/changes based on our needs. Also we need the freelancer to examine the charges on the AWS server and how we can minimize them. The ideal candidate should have a strong background in developing and deploying applications in cloud environments, particularly AWS. You'll be responsible for troubleshooting issues, optimizing performance, and implementing new features as needed. If you have a passion for coding and a commitment to delivering high-quality solutions, we would love to hear from you!
