You will get front-end code review of your app (React and Next.js)
Project details
Get a professional front-end code review of your React / Next.js application.
I analyze your codebase to identify architectural issues, maintainability risks, and potential scalability problems before they turn into costly refactoring. This is especially useful if your app was built quickly, by multiple developers, or is starting to grow in complexity.
I focus on real-world production concerns — not just style or linting.
I review your codebase to identify:
• architectural, maintainability and scalability problems
• anti-patterns
• bad practices
What you’ll get:
• concise written feedback
• prioritized list of issues
• practical suggestions you can apply immediately
Scope & notes:
• no performance benchmarking or profiling
• no code changes
This service is designed to give you a second opinion on your codebase without long calls or overcomplicated reports. Code changes and implementation can be discussed.
Send me a repository link and a short description of your goals or concerns, and you’ll receive structured, actionable feedback without unnecessary overhead.
P.S.
Very large or unusually complex codebases may require a custom offer depending on scope.

Full Stack Developer | E-com | React Angular Vue | Web development
Dnipro, Ukraine - 6:07 am local time
My work spans MedTech, FinTech, and e-commerce, covering both B2B and B2C platforms. I’ve launched and supported production-ready solutions for some of the largest companies in Ukraine, including PrivatBank, TASCOMBANK, Podorozhnik, and Citrus.
I take ownership of the entire development process — from architecture decisions to deployment and support.
