Why Choose MicrocosmWorks for Performance Optimization?
Slow applications lose users, revenue, and SEO rankings. We take a data-driven approach to performance — profiling every layer of your stack, identifying the highest-impact bottlenecks, and implementing solutions that deliver measurable improvements. No guesswork, just measured results.
Our Performance Optimization Capabilities
- Full-Stack Profiling — Profile frontend rendering, network waterfalls, API response times, database queries, and infrastructure utilization to identify root causes.
- Frontend Performance — Optimize Core Web Vitals (LCP, FID, CLS), implement code splitting, lazy loading, image optimization, and critical rendering path improvements.
- Backend Optimization — Fix N+1 queries, implement caching layers, optimize serialization, and reduce API response times from seconds to milliseconds.
- Database Tuning — Analyze query plans, add strategic indexes, implement connection pooling, and optimize schema design for your access patterns.
- Infrastructure Right-Sizing — Match resources to workloads, implement auto-scaling, optimize container configurations, and reduce cloud costs.
- Monitoring & SLOs — Establish performance budgets, set up real-time monitoring, and create alerting that catches regressions before users notice.
Technology Stack
We use Lighthouse, WebPageTest, and Chrome DevTools for frontend analysis; APM tools (DataDog, New Relic) for backend profiling; pg_stat_statements and EXPLAIN ANALYZE for database optimization; and k6 for load testing. Results are validated with real user monitoring.
Who This Is For
Applications suffering from slow page loads, high API latency, poor Lighthouse scores, or degraded performance under load. Whether you're preparing for scale, fixing user complaints, or optimizing for SEO and conversion rates, we deliver measurable performance gains.
Our Process
1
Performance Audit
Comprehensive profiling across all stack layers. Identify top bottlenecks and quantify improvement potential.
2
Optimization Plan
Prioritize fixes by user impact and effort. Set target metrics and define success criteria.
3
Implementation
Execute optimizations — caching, query fixes, bundle optimization, infrastructure tuning.
4
Validation
Load test, measure improvements against baselines, and validate under production-like conditions.
5
Monitoring Setup
Deploy performance dashboards, set budgets and alerts, and establish regression prevention.

Frequently Asked Questions
We optimize the full application stack including frontend rendering, API response times, database queries, memory usage, CPU utilization, network latency, and third-party service calls to deliver a fast, responsive user experience.
Application performance optimization at MicrocosmWorks is available at $20-$50/hour. We prioritize optimizations by impact, so you see the biggest improvements early in the engagement.
Yes, we optimize React and Next.js applications by implementing code splitting, lazy loading, server-side rendering, image optimization, bundle size reduction, memoization, and virtual scrolling to achieve sub-second page loads.
We use distributed tracing with tools like Jaeger or Datadog APM, frontend profiling with Lighthouse and Web Vitals, and backend profiling to trace every request from browser to database, identifying exactly where time is spent.
Yes, we specifically optimize Largest Contentful Paint, First Input Delay, and Cumulative Layout Shift by addressing render-blocking resources, optimizing images, reducing JavaScript execution time, and implementing proper layout reservations.
