Objective We need an expert front-end developer to conduct an unbiased, in-depth audit of our codebase — focusing on long-term scalability, performance, security, maintainability, and compliance with industry standards. The goal is to receive a detailed, actionable, and critical report, not a surface-level review. Scope of Work Evaluate architecture, modularity, and state management for scalability and maintainability. Assess performance: bundle size, lazy loading, caching, and build optimization. Audit for front-end security risks (XSS, CSRF, token handling, dependency vulnerabilities). Check accessibility (WCAG 2.2), code quality, and compliance with standard practices. Review testing strategy, CI/CD setup, and code quality tools. Deliverables Detailed Audit Report (10–30 pages) with findings, severity levels, and concrete recommendations. Prioritized Fix List with effort estimates and clear next steps. Sample Fixes or Code Snippets showing how to address critical issues. Executive Summary highlighting top risks and improvement roadmap. Requirements Proven experience auditing large-scale React/Next.js (or relevant stack) apps. Strong expertise in front-end architecture, performance tuning, and security. Clear, technical writing and ability to justify findings with evidence. Must sign NDA before receiving access to code or repository. What to Include in Your Proposal Brief background + sample audit or report (redacted OK). Tools and methodology you use (e.g., Lighthouse, WebPageTest, dependency scanners). Estimated timeline and fixed-price quote. Deliverable Expectation: An honest, critical, and detailed audit document, written by a senior developer, not generic advice.
