You will get Next.js Code Audit + Cleanup - Production-Ready in 7 Days
Top Rated
Project details
Most SaaS codebases I review have the same set of problems: missing TypeScript types, no error boundaries, hardcoded API keys, leaky auth, untested critical paths, and a bundle size that takes 8 seconds to load on mobile. Your senior engineer would catch these in a two-hour review. You probably do not have one yet.
I do senior-level code reviews for Next.js and React applications, deliver a prioritized fixes report, and (in higher tiers) implement
the critical refactors so your codebase is production-ready before your next launch, fundraise, or hire.
WHAT YOU GET
• Full senior code review of your Next.js or React codebase
• Prioritized fixes report: critical, high, medium, low severity
• Security check: env handling, auth flows, exposed endpoints
• Performance scan: bundle size, render bottlenecks, query waste
• Top tier: full refactor with tests, docs, CI/CD ready
WHY ME
Frontend Lead at an enterprise platform. Years migrating legacy codebases (PHP Yii to Laravel microservices). I do not just find problems - I tell you which ones matter for YOUR roadmap.
NEXT STEP
Share repo access. First-pass review within 24 hours.

Hijab and Ammar helped us to rebuild our website - they did so with a great attention to detail and quality, making sure that all of the animations and information was accurate whilst taking feedback in-flight. Great communicators and fast work.

Mia-OS Front End Development
Hijab took our vision and brought it to life across three complete applications our public marketing site, our customer portal, and our internal admin dashboard. Built end-to-end on Next.js, React, TypeScript, and Tailwind, every product she shipped is polished, animated, type-safe, and production-ready. She owns features from design through deploy, communicates clearly, and is consistently outcome-focused. When requirements changed, she stayed flexible and dynamic, offering clear options and trade-offs, then executing without drama. She’s well-versed in modern front-end tools and workflows and needs minimal direction to take designs from handoff to polished, production-ready UI.Code is organized and maintainable, performance is considered, and her testing and QA instincts are strong. Collaboration was smooth—concise standups, thoughtful questions, realistic estimates, and dependable delivery. Bottom line: she elevated the product, reduced my management overhead, and proved to be the most effective front-end developer I’ve worked with to date; I’d rehire her immediately and recommend her without reservation.

Hijab delivered numerous major milestones for my React/TypeScript project, and I truly enjoyed working with her. Her communication was seamless throughout, and she consistently met deadlines — often even working weekends when needed to keep progress on track. She demonstrated a strong willingness to tackle challenging issues and handled multiple tasks and projects with impressive reliability. I especially appreciated her attention to detail in ensuring pages matched the Figma designs precisely. She was also very receptive to feedback during PR reviews and quick to incorporate improvements. Overall, a 10/10 experience — I would gladly work with her again in the future.

Steps for completing your project
After purchasing the project, send requirements so HIJAB can start the project.
Delivery time starts when HIJAB receives requirements from you.
HIJAB works on your project following the steps below.
Revisions may occur after the delivery date.
Repository Access and Context Gathering
You share repo access and answer the requirements form. I confirm the framework versions, deployment setup, and your top 3 concerns to prioritize correctly within the audit window.
Initial Codebase Walkthrough
I clone the repo, install dependencies, and run the project locally or against a staging environment. I verify the build, type-check, lint, and test commands all execute and document any that do not.
