You will get a frontend audit for performance, accessibility and UX issues
Project details
I help SaaS teams identify and fix real frontend issues that affect performance, accessibility, and user experience.
This is not a generic audit. I focus on production problems in React and Next.js applications, slow load times, poor Core Web Vitals, accessibility gaps, and frontend architecture issues.
What you will get:
• a clear list of prioritized issues (high, medium, low)
• concrete, actionable fixes you can implement immediately
• performance insights (LCP, CLS, rendering, bundle size)
• accessibility issues with practical solutions
If your app feels slow, hard to maintain, or has UX issues, this audit will give you a clear direction on what to fix first.

Senior Frontend Engineer | React, Next.js, TypeScript, A11y
Rijeka, Croatia - 4:18 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.
