Interfaces that stay fast under real traffic
React, Vue and modern JavaScript builds where design fidelity and performance are non-negotiable. Page speed, web traffic and website performance optimization are the skills our clients endorse us for most.
How we build frontends
Ship HTML, not a loading spinner.
Server-first rendering, hydration only where things actually move — a third less JavaScript before optimization even starts.
Fast on your laptop means nothing.
Google scores 28 days of real users at the 75th percentile. We watch field data, not Lighthouse screenshots.
Regressions die in code review.
Performance budgets run on every pull request — a slow merge is a blocked merge, not next month’s mystery.
The design system outlives us.
Tokens, Storybook, visual regression tests — built to survive handover to your own team.
What we obsess over
Open each one — this is the checklist your build is measured against before we call it done.
LCP, CLS and INP measured on real devices, not just Lighthouse on a MacBook. Performance budgets are set at the start of the project, not discovered at the end.
Frontend performance is business performance
Not our opinion — measured results from Google, Deloitte and the HTTP Archive. This research is why we treat speed as a feature.
0.1 seconds = 8.4% more sales
Deloitte and Google measured 37 brand sites across 30+ million sessions: a 0.1s improvement in mobile speed lifted retail conversions 8.4% and order value 9.2%. Milliseconds are revenue.
Most of the web fails the bar
Only 48% of mobile sites pass all three Core Web Vitals (Web Almanac 2025). Passing is not hygiene — it is a competitive advantage most of your competitors do not have.
INP is the new hard part
Since March 2024 Google measures responsiveness (INP), and it is now the hardest vital to pass on interactive UIs. It rewards disciplined JavaScript — main-thread work under 50ms — not lucky lab runs.
Field data beats Lighthouse screenshots
Google judges the 75th percentile of 28 days of real-user data. A perfect Lighthouse score on a fast laptop proves nothing, which is why we wire up real-user monitoring and CI budgets that block regressions before they merge.
Ship less JavaScript
The median page ships ~697 KB of JavaScript and roughly 250 KB of it never executes (HTTP Archive). Server-first rendering — now the industry default — typically cuts bundles 20–40%.
The proof it pays
Rakuten measured +53% revenue per visitor after investing in Core Web Vitals; Vodafone got 8% more sales from a 31% LCP improvement. Google publishes these case studies — links below.

Which frameworks do you actually work in?
React and Next.js, Vue and Nuxt, plus classic Twig templating for Craft CMS builds. We pick per project — and will tell you when a framework is overkill.
Can you work inside our existing design system?
Yes — a large share of our work is embedding into established teams and codebases (Fandom, Australian Ballet, Grill’d) and matching their standards, not replacing them.
How do you keep animations from hurting performance?
Transform-only animation, will-change discipline, lazy-loading heavy assets, and profiling on mid-range phones. Motion is part of the performance budget, not exempt from it.
Can you guarantee a 100 Lighthouse score or passing Core Web Vitals?
Nobody can honestly guarantee field data — Google evaluates 28 days of real users at the 75th percentile, and a third-party script added after launch can undo any lab score. What we commit to: a defined performance budget, CWV targets at handover, CI that blocks regressions, and real-user monitoring so problems surface in dashboards, not in lost rankings.
Do we need a full rebuild, or can you refactor what we have?
Incremental refactoring is usually cheaper and lower-risk — big-bang relaunches concentrate all SEO and UX risk into one day. A rebuild earns its cost when the architecture is fundamentally broken or the framework is end-of-life. We audit first, and sometimes the honest verdict is that you do not need us yet.
