Performance Optimization
Freelance full-stack developer in Pakistan, based in Gujranwala — fixed scope, written timeline, daily updates.
Slow products leak revenue. I run performance engagements on React and Next.js applications: measure, fix the top bottlenecks, then lock the wins in with budgets so regressions can't sneak back after I leave.
The wins usually come from four places: rendering strategy (server components, streaming, correct caching), bundle diet (dependency audits and code splitting), the data layer (Redis caching, query tuning, payload pruning), and asset discipline (next/image, font strategy, edge delivery via Vercel or AWS).
This portfolio is itself the demo: fully server-rendered HTML, optimized images, and zero layout shift on load — built to pass Core Web Vitals on a mid-range phone in Karachi or a laptop in London.
What's included
Audit & baseline
Lighthouse and field data analysis, with a ranked bottleneck report — what to fix first and what it's worth in milliseconds.
Rendering fixes
Server components, streaming, cache headers, and ISR where it fits — so pages render fast and stay fast.
Data-layer speed
Redis caching, query optimization, and payload pruning for dashboards and heavy lists.
Budgets & monitoring
Performance budgets wired into CI so the speed wins survive your next ten releases.
Who this is for
- —Products failing Core Web Vitals
- —Apps with slow dashboards or heavy lists
- —Teams preparing for a launch or traffic spike
- —Anyone whose mobile users are on Pakistani 3G/4G networks
