You will get Senior React and Next.js Code Review and Architecture Assessment
Project details
I review React and Next.js codebases from a senior engineering perspective, focusing on architecture, maintainability, and long-term scalability.
This is not a superficial code review. I analyze how your application is structured, how data flows through the system, and where technical debt or hidden risks may slow you down as your product grows.
You will receive a clear, actionable report with prioritized issues, explanations, and practical recommendations your team can implement.
This is especially useful for teams preparing to scale, refactor, or stabilize an existing codebase.

Frequently asked questions
About Sinisa
Senior Frontend Engineer | React, Next.js, TypeScript, A11y
Rijeka, Croatia - 5:31 am local time
I am a Senior Frontend Engineer with 18+ years of experience building complex web applications, specialized in React, Next.js, TypeScript, frontend architecture, performance, accessibility, and long term maintainability.
Clients usually bring me in when a frontend has grown messy, performance has become a real problem, accessibility needs proper implementation, or a React / Next.js codebase needs senior level refactoring without disrupting delivery.
I work especially well on long lived products, complex user flows, legacy codebases, reusable UI foundations, and frontend systems that need both technical judgment and practical execution.
What I can help with:
- React and Next.js development
- TypeScript codebases
- frontend architecture and refactoring
- performance optimization
- accessibility and WCAG minded implementation
- reusable component systems
- code reviews and technical audits
- stabilizing and improving legacy frontends
I care about clarity, maintainability, and shipping work that still makes sense months later.
