Our approach

Performance: every millisecond counts

A slow site means lost users and revenue evaporating. We build applications that are fast from day one and optimize the ones that aren't.

Why performance is business-critical

53% of users abandon a site that takes more than 3 seconds to load. Google penalizes slow sites in its rankings. Performance is not a technical luxury, it's a measurable competitive advantage.

  • Load times under 2 seconds to maximize conversions
  • Core Web Vitals optimized for SEO and user experience
  • Architecture built to scale: from 100 to 100,000 users
  • Continuous monitoring: we catch regressions before your users do

Our performance approach

The technical fundamentals we apply systematically

01

Measure first

Before optimizing, we measure. Lighthouse, WebPageTest, RUM monitoring. We identify the real bottlenecks.

02

Critical path optimization

We cut time to first render: inline critical CSS, lazy loading, smart prefetching.

03

Optimized assets

WebP/AVIF images, subsetted fonts, bundle splitting. Every kilobyte counts on mobile.

04

Smart caching

CDN, browser cache, ISR (Incremental Static Regeneration). We serve content from the edge, not from the server.

05

Optimized database

Relevant indexes, optimized queries, connection pooling. The backend should never be the weak link.

Performance by design

Performance is not an afterthought at PeakLab. It's baked into the stack choice, the architecture, and every technical decision. We don't build a slow site and optimize it later.
