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.

Sinisa gets my highest marks. He's consistent, talented, and loyal. We went through tons of tough times over the past few years, and he stuck with us through thick and thin.
When other remote engineers on our team lacked commitment or had poor communication, he really got in their stuff, encouraging everyone on the team to hold themselves to as high a standard of professionalism as he holds himself.
Sinisa can really make a team, and his work product is exceptional. Hire him before someone else does, and pay him whatever he asks for. He's worth it.

About Sinisa
Senior Frontend Engineer | React, Next.js, TypeScript, A11y
Rijeka, Croatia - 9:59 pm 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.
