Senior frontend engineer (6+ yrs) shipping production React, TypeScript and Angular apps for enterprise clients in the US, UK and Ireland. Currently building the frontend of a large ERP platform (stealth). On Fiverr I rescue vibe-coded apps (Lovable, Base44, Replit, Bolt): Supabase auth and RLS, broken builds, failed deploys, security holes, then make them production-ready. Also n8n and AI-agent automations, and Chrome extensions (two published on the Web Store). Clear scope before you order, root causes explained in plain English, fast replies.

FAQ
What frameworks and tools do you work with?
Angular (all versions 2–20), React, Next.js, Vue, TypeScript, webpack, esbuild, Vite, and Rollup. If your app uses a modern JavaScript framework, I can optimize it.
What will I receive in the audit report?
A detailed PDF covering Lighthouse scores, Core Web Vitals breakdown, bundle size analysis, render-blocking resources, and a prioritized list of fixes ranked by performance impact and implementation effort
How much faster will my app get?
Results vary by app, but typical improvements are 30–60% better load times and significantly improved Core Web Vitals scores. I’ll give you an honest estimate after reviewing your app before you order.
Do you need access to my codebase?
For the Basic audit, I only need your live URL. For Standard and Premium packages, I’ll need read access to your Git repository. All code is treated as strictly confidential.
Will you actually implement the fixes or just report them?
Basic is report-only. Standard includes fixing the top 5 issues. Premium is a complete optimization where I implement all recommended changes and verify improvements with before/after metrics.
Can you help with WordPress or Shopify speed?
No. I specialize exclusively in JavaScript application performance (Angular, React, Vue, Next.js). For WordPress/Shopify, there are many great sellers on Fiverr who focus on those platforms.
Should I message you before ordering?
Yes, please! A quick message lets me review your app, confirm the right package, and set accurate expectations. This ensures we’re both aligned and you get maximum value.
