I make your applications faster and your infrastructure ready for growth. I find the bottlenecks, fix them, and put systems in place so performance stays excellent as you scale up.
Systematic profiling of your application covering database queries, API response times, frontend load speed, and resource utilisation. Data-driven analysis that pinpoints exactly where time is being wasted.
Query tuning, index optimisation, connection pooling, read replicas, and caching strategies. I turn slow database interactions into millisecond responses.
Multi-layer caching with Redis, CDN edge caching, and application-level caching. This dramatically reduces load on your origin servers while keeping data fresh.
I simulate real-world traffic patterns to find breaking points before your users do. Capacity planning ensures your infrastructure grows ahead of demand, not behind it.
Core Web Vitals optimisation, bundle size reduction, lazy loading, image optimisation, and rendering performance. I make your application feel instant for every user.
Systems that scale automatically with demand and degrade gracefully under pressure. Circuit breakers, queue-based architectures, and failover strategies that keep you online.
Establishing baselines with real metrics and identifying the biggest bottlenecks.
Targeted fixes, biggest impact first, measured with each change.
Infrastructure changes to handle growth: caching, CDNs, and auto-scaling.
Ongoing performance tracking with alerts for regressions.
Let's discuss how I can help bring your project to life.
