You will get Your Next.js App Optimized For Speed And Core Web Vitals
Project details
Slow load times cost you rankings and users, Google's Core Web Vitals directly affect Next.js SEO, and every extra second of load time measurably increases bounce rate. I fix the specific things actually slowing your app down, not generic advice you've already read.
This is the same optimization work that cut dashboard load times by 40% on a production SaaS platform I built, through SSR tuning, structured caching, image optimization, and bundle size reduction, not guesswork.
What you get: a full performance audit identifying your real bottlenecks, then targeted fixes, server-side rendering strategy, caching, image and font optimization, and bundle analysis, with before-and-after metrics so you can see exactly what improved.
Send me your live URL or repo access, and I'll show you where the actual bottlenecks are before proposing any fix.

Job Success
Gilgit, Pakistan - 6:53 am local time
I'm a full-stack engineer with 8 years building production web applications, the last several years specifically inside the modern Next.js stack, App Router, TypeScript, Tailwind CSS, deployed on Vercel, backed by Supabase or PostgreSQL. I've led development on SaaS platforms used by real users daily, not portfolio demos.
What I bring to your project:
✔ Next.js (App Router), React, SvelteKit, TypeScript — daily stack, not a side skill
✔ Node.js backend architecture, REST API design, and clean API integration with third-party services
✔ Supabase / PostgreSQL — schema design, auth, row-level security, real-time features
✔ Stripe payment integration, webhook handling, subscription logic
✔ Tailwind CSS + pixel-perfect Figma-to-code implementation
✔ Vercel deployment, CI/CD, and Next.js SEO/performance optimization done right from the start
✔ Comfortable reviewing and hardening AI-generated code (Claude, Cursor, v0) and integrating OpenAI/Claude APIs cleanly into production apps
Proof, not just claims:
✔ Co-led front-end and backend development on an HR SaaS platform used by thousands of employees daily
✔ Cut dashboard load times by 40% through SSR optimization
✔ Reduced a client's manual operations by 70% through workflow automation
✔ Built and shipped multi-tenant systems, real-time dashboards, and role-based access control for platforms handling live user data
How I work:
✔ I read your actual codebase or spec before quoting anything — no generic timelines
✔ I test every change and flag risks before they become problems, not after
✔ I communicate early if something's blocked — no silent delays
✔ I don't rewrite what doesn't need rewriting, and I don't over-engineer what does
Availability: Full-time, 30+ hours/week, available to start immediately. I'm based in Gilgit, Pakistan (GMT+5), and I typically respond within 0–4 hours, most of my working day overlaps well with US morning/evening hours and all of European business hours.
If your Next.js app needs to go live, needs fixing, or needs a backend built underneath a frontend that's already designed, send me your repo, your Figma files, or just a description of what's broken. I'll give you a straight answer on scope and timeline before you commit to anything.
