You will get a modernized React/Next.js app — Vite, latest React, zero known CVEs

Project details
You will get your aging React or Next.js app brought fully up to date — safely. Stuck on Create React App, an old React version, or a pile of outdated dependencies with security warnings? I migrate React apps to modern tooling incrementally, behind a test safety net, so nothing silently breaks along the way.
Proof: I led a full frontend modernization of a legacy platform — CRA → Vite, React 17 → 19 across 6 major dependency upgrades (React Router, TanStack Query, Headless UI, Tailwind), shrank node_modules from 446 MB to 272 MB, and eliminated all 41 known vulnerabilities across 138 dependency paths.
You get a current, secure, maintainable codebase — with the upgrades explained so your team knows exactly what changed and why. Scope agreed in writing, clear communication throughout, and smoke tests so you can trust the result.

About Ahmad
React/Next.js Engineer | Test Automation & AI-Augmented Dev
Berlin, Germany - 8:30 pm local time
I specialize in two things teams usually struggle to find time for:
Test automation & TDD retrofit
Your app works, but every release is a gamble. I add real Vitest + Playwright test suites (unit + end-to-end) so you can ship without breaking things. Recent results:
- Raised one React app's coverage from 4.82% to 97.19%
- Built 2,000+ automated tests with 3 enforced quality gates on a production app
React/Next.js legacy modernization
Stuck on an old stack with security warnings piling up? I handle the migrations cleanly, without breaking your app:
- CRA to Vite, React 17 to 19
- Eliminated 41 CVEs and upgraded 6 major dependencies on one codebase
My stack: React, Next.js, TypeScript, JavaScript, Vitest, Playwright, Vite, CI/CD (Jenkins), dependency & supply-chain security (Renovate, SBOM/CycloneDX).
I work test-first, communicate clearly, and scope everything in writing before I start. Based in Berlin (fluent English, C1 German) — comfortable working with international teams across time zones.
If you need your React app tested, modernized, or both — let's talk.
Steps for completing your project
After purchasing the project, send requirements so Ahmad can start the project.
Delivery time starts when Ahmad receives requirements from you.
Ahmad works on your project following the steps below.
Revisions may occur after the delivery date.
Audit & plan
I review your stack, run a dependency/security audit, and give you a clear, prioritized upgrade plan.
Incremental migration
I perform the migration/upgrades in safe, reviewable steps (build tool, React version, dependencies), resolving breaking changes as I go.
