Expletech are performance engineering experts for web apps, SaaS platforms, and high-load systems. Lighthouse 100/100, Core Web Vitals, and measurable business impact.
Milliseconds cost real money
Every 100ms of latency reduces revenue. We diagnose, optimize, and monitor your product until it's fast enough to delight users — and rank higher on Google.
Slow products bleed revenue
Users abandon pages that take more than 3 seconds to load. Google demotes slow sites. Your competitors keep shipping — while you debug.
Users Leave Before It Loads
A 1-second delay in page load drops conversions by 7%. Slow sites bleed users every minute they stay unoptimized.
Google Penalizes Poor CWV
Core Web Vitals are a direct Google ranking factor. Poor LCP and CLS scores push you down in search results — and drive traffic to competitors.
Database Queries Choke Under Load
N+1 queries, missing indexes, and inefficient joins turn peak traffic into downtime. The bigger you grow, the worse it gets.
Cloud Bills Spike With Traffic
Unoptimized infrastructure and bloated bundles cause compute costs to skyrocket. You're paying for problems, not growth.
End-to-end performance engineering
We fix performance from the browser rendering pipeline to the database query plan — no surface left untouched.
Core Web Vitals & Rendering
We eliminate render-blocking resources, fix CLS jumps, and optimize LCP to hit 90+ Lighthouse scores on mobile and desktop.
- LCP / CLS / INP optimization
- Bundle splitting & tree-shaking
- Image & font pipeline
Database & API Speed
We profile slow queries, add smart indexes, introduce caching layers, and restructure API responses to reduce server response time to under 100ms.
- Query profiling & indexing
- Redis / CDN caching
- API response optimization
Cloud & CDN Setup
Proper CDN configuration, edge functions, HTTP/2, Brotli compression, and server-side optimizations that make a measurable difference at scale.
- CDN & edge deployment
- Compression & HTTP/2
- Container right-sizing
Ready to make your product blazing fast?
Let's diagnose your bottlenecks and build a clear optimization roadmap.
Speed is a
growth lever
Performance optimization isn't just technical hygiene — it directly moves your revenue, rankings, and user retention metrics.
Measured outcomes
Faster pages mean less friction. Users buy more when they don't wait.
Core Web Vitals improvements directly boost your Google position.
Sub-second load times keep users engaged instead of leaving.
Leaner code and better caching reduce compute spend without cutting capability.
From slow to lightning fast
We follow a proven 4-phase process — from deep diagnostics to validated, stable performance gains you can measure.
Powered by industry-grade tools
We combine automated profiling with manual expert analysis to cover every layer of your stack.
Frontend & CWV
Browser-side profiling and Lighthouse auditing.
Once fast, stay ahead of the curve
After optimization, many clients engage us for ongoing Technical Audits, DevOps, or Dedicated Teams to maintain and improve performance as the product scales.
