What a performance engineer from Krapton does
Hire a performance engineer from Krapton when your website or web app is slow and nobody on the team has time to find out why. A performance engineer measures first, with real-user data, Lighthouse, WebPageTest and profiler traces, then fixes the causes: oversized JavaScript, render-blocking resources, slow server responses, heavy images and third-party scripts, and database queries that do not scale.
The job does not end with a better score on one day. A good performance engineer adds budgets and checks to CI and monitoring to production, so a later release cannot quietly undo the gains, and explains each change so your developers keep the habits.
What we vet performance engineers for
Performance work is diagnosis first. These are the skills we test for.
Measuring before fixing
Reading field data from CrUX and real-user monitoring alongside lab tools, and knowing why the two disagree.
JavaScript and rendering
Profiling long tasks, hydration cost, bundle make-up and rendering strategy in React and Next.js.
Core Web Vitals
Practical fixes for LCP, INP and CLS: resource priority, script scheduling, layout stability and font loading.
Network and caching
CDN and HTTP caching, compression, modern image formats, and preload or preconnect used only where they help.
Back-end latency
Server response time, slow SQL and N+1 queries, caching layers, and behavior under a load test.
Guarding the gains
Performance budgets in CI, synthetic monitoring and alerts, and notes the team can follow.
Work our performance engineers are hired for
- Failing Core Web Vitals. Search Console marks pages as poor and rankings or conversions are at risk.
- Slow web apps. Dashboards and SaaS products that feel sluggish on real devices and networks.
- Reviews before a launch. An audit and fixes before a redesign, migration or marketing campaign.
- Load and scaling problems. APIs and databases that slow down as traffic or data grows.
Hear from teams that hired our performance engineers
Founders and product leaders sharing what it was like to build with Krapton.
“Quick, Professionals, Always going above and beyond.”
“Rush Racing League needed more than just a website — we needed a full system that could run as fast as our races. Krapton built exactly that. Live race results flow automatically from Discord straight to the website — no manual updates, no delays. Team management is seamless, driver rosters update in real time, and our admin panel lets us control every piece of content on the site without touching a single line of code. They didn't just build us a product — they built us a machine. Huge thanks to the Krapton team.”
“Krapton built our admissions platform end-to-end — content, SEO, dashboards. Enquiries from international students grew steadily after launch.”
- Admissions platform delivered ahead of schedule
- SEO + content built into the launch, not bolted on after
- Ongoing engagement for new courses and dashboards

Frequently asked questions
Quick answers to the questions teams ask before getting started.
What does a performance engagement look like?
Week 1: we measure how your site is performing today. Week 2: we fix the slowest parts. Week 3: we put automatic checks in place so it stays fast. You get a clear before/after report.
Frontend, backend, or both?
Both. Our performance engineers cover page speed, image and bundle work, server response times, database queries and load testing.
What kind of results should I expect?
Most clients see clearly faster pages within 2–3 sprints. We promise measurable improvement — if we don't deliver, we extend at no extra cost.
How do you stop the gains from regressing?
We install automatic checks that flag any change which slows the site down — so the speed wins stay won, not just for one launch.
Can you audit without implementing?
Yes — fixed-scope audits are available. You get a prioritised fix-list your own team can ship.
