Make your site or web app fast → get more revenue & happier users

education

We worked with Google on educating developers about web performance. This targets the long-term goal of making the web faster.

• A guide to making web apps faster with webpack
• A list of tricks to optimize dependencies
• A training project to practice optimization strategies

This is some of the highest quality tutorial style documentation on webpack I’ve come across

Hugo helps to keep meeting notes and tasks in one place.

react performance

core web vitals

The Hugo team was noticing their React app was slow here and there. They weren’t sure what was causing that, so they reached out to PerfPerfPerf for help.

We identified multiple loading and runtime performance optimizations and guided Hugo through implementing them. As a result, Hugo’s JS init time decreased 2.5×, the editor input latency improved 1.7×, and the Lighthouse score (even not being a goal) increased by 23 points.

We were more than satisfied working with Ivan. Ivan communicated very well throughout the whole process, and the level of detail in his suggestions and recommendations was just outstanding.

Finder helps 2 million Australian customers track spending, find deals, and save money.

core web vitals

A huge chunk of Finder’s new customers come to Finder from search. Finder wanted to make the site faster and grow their organic traffic, and they asked us to help.

We helped Finder to move Core Web Vitals to green for 98% of their pages. As a result, Finder’s organic traffic grew 50%, and conversion also increased.

Castor is a tech platform that makes clinical trials easier.

Castor reached out to us when they were building a new product. They noticed the product’s bundle was too large, realized Castor’s design system caused this, but weren’t sure how to fix it.

We jumped in and made the design system load faster. We also optimized the runtime performance of a few critical components, increasing their responsiveness from 1..2 to 20..30 FPS.

In just a couple weeks, Ivan significantly improved runtime performance and tree shaking of our key components. One of our products’ bundle got 3 times smaller – with 10× less JS needed for the initial load.

Appsmith is a low-code platform for building internal apps.

react performance

With Appsmith, we did three React rendering performance audits. This helped us to focus on different aspects of app’s UI speed. With audit recommendations implemented, the app got 1.9…2.8× faster across multiple user interactions.

This customer was an enterprise marketing agency with an undisclosed name.

lighthouse score

PerfPerfPerf worked with an enterprise marketing agency to push its site’s PageSpeed Insights score from ~50 to ~95. This was critical for converting customers – before the optimizations, some customers would see a poor score and churn away.

We analyzed the site, found every issue affecting the score, figured out how to solve them, and guided the team through implementing the solutions.

Ivan’s advice was all exceptionally clear. I really appreciated Ivan including his whole thought process, including what he tried that may not have worked – before arriving at a final solution.

Ivan’s responsiveness was a godsend and a clear cut above any other consultants we’ve used in the past, and the overall level of organization + timetable he brought was truly fantastic!

Framer is an website design tool.

For Framer, higher performance means happier users and better retention.

We worked with Framer to perfect the loading speed of Framer UI and Framer Sites. At the Framer UI, we reduced Speed Index and First CPU Idle of the UI by 40-45%. With Framer Sites, we’ve been working together to improve the Core Web Vitals and the Lighthouse score. We also improved the performance of internal tools, to make engineers more productive and save costs.

We’ve been very satisfied by working with Ivan! Ivan helped us to improve loading performance, runtime performance, and tooling around it. The quality of his work, approach, documentation, etc. has been outstanding.
