We are looking for a MERN specialist who can take full ownership of a production-grade web application. The immediate focus is on modelling a complex data structure: expect dense many-to-many relationships that demand rock-solid data integrity and expressive, lightning-fast queries in MongoDB. Beyond the database layer, you’ll be building and hardening REST endpoints in Express/Node, wiring in third-party services, and tying everything together with a clean React front-end. Firebase will handle authentication, real-time messaging, and push notifications, so any prior experience there is a plus. On the infrastructure side, you’ll manage Docker-based deployments to AWS or DigitalOcean, keep CI/CD pipelines humming, configure domains and SSL, and watch logs and uptime dashboards to catch issues before our users do. Security matters: role-based access control, secure file uploads, and well-guarded APIs are non-negotiable. Deliverables • Optimised MongoDB schema supporting many-to-many relations with advanced querying and integrity safeguards • Secure REST API layer, documented and fully tested • React components that consume these APIs seamlessly • Automated Docker pipeline from commit to production (AWS/DigitalOcean) • Monitoring, alerting, and performance tuning in place If you thrive on solving data-heavy challenges while keeping servers, pipelines, and users happy, let’s talk.
