Full-Stack Velocity
Unifying frontend and backend performance to build faster, more engaging web experiences by optimizing the entire request chain.
Performance is a Full-Stack Story
Unified Observability
Combine frontend RUM, backend APM, and tracing to get a complete picture of the user journey and pinpoint the true source of delays.
Perceived Performance
Use skeleton screens, optimistic UI updates, and lazy loading to make the application feel faster, even when backend work is ongoing.
Correlation Analysis
Move from guesswork to data-driven optimization by linking specific backend latencies to frontend user experience metrics like LCP and TTI.
The Performance-First Workflow
A continuous cycle of testing and optimization is crucial. Always validate changes under realistic load, not just in local development environments.
A Coordinated Attack Plan
Frontend Tuning
- βLazy load images & components
- βMinimize request counts (batching)
- βTrim payloads (GraphQL, field selection)
- βUse modern image formats & compression
Backend Tuning
- βOptimize slow database queries & add indexes
- βImplement multi-layer caching (memory, CDN)
- βUpgrade server resources & infrastructure
- βUse asynchronous workers for long tasks
Overcoming Common Hurdles
Challenge: Attribution is hard. Where is the actual slowdown?
Solution: Implement unified observability tools that connect user actions on the frontend (RUM) with backend service performance (APM) to trace the full request lifecycle.
Challenge: Micro-optimizations distract from real bottlenecks.
Solution: Use load testing and APM data to identify the critical pathβthe sequence of requests that most impacts user-perceived metrics like LCP. Focus optimization efforts there first.
Challenge: Performance degrades under real-world traffic.
Solution: Validate all performance improvements with load tests that simulate realistic user concurrency and traffic spikes. Local benchmarks are not enough.
