You will be taking full ownership of a brand-new MERN stack build, wiring MongoDB, Express, React and Node.js into a single, cohesive product. The codebase must follow modern JavaScript (ES6+) practices, leverage HTML5 semantics and clean CSS3, and expose or consume well-structured RESTful APIs. Quality and performance matter: I will review your commits, run the test suite, and profile the app to confirm robust error handling, efficient database queries and minimal bundle size. Expect to tackle real-world debugging scenarios, tune performance, and document every decision so the project stays maintainable. Deliverables • End-to-end MERN application pushed to a Git repo • Clear setup/launch instructions in a concise README • Commented, lint-clean ES6+ code with meaningful commit history • Brief performance report highlighting optimizations made Ship workable increments—feature branches and pull requests are welcome—and be ready for quick feedback rounds as we refine the product together.

Hi, React bundle size and slow Mongo queries will likely be the first user-facing issues given your emphasis on performance and minimal bundle size. You want a full MERN app with ES6+, RESTful APIs, and documented commits — I’ll enforce linted code, meaningful commit history, and a concise README. Initial debugging/build angle: - profile React bundle (code-splitting, tree-shaking) and optimize critical routes - analyze Mongo queries (indexes, aggregation pipeline) and fix N+1 or unindexed filters I’ll deliver incremental PRs, run tests, and include a short performance report noting any data or uptime risks. Ready to start first sprint and open the repo access? — Smith
