A ton of extremely useful, actionable feedback that directly and significantly improved our First Meaningful Paint, Time to Interactive, [and] Speed Index
What: we’ll analyze the site, identify all performance issues, and compose a document with potential optimizations.
Great when: you have a team that wants to learn a lot about their website performance, and that is ready to implement all optimizations themselves.
I want to marry that audit document ❤️ the level of detail, including going through our own codebase and pin-pointing where exactly improvements need to happen, it’s just... wow
Want an example? See this public Notion case study.
What: we’ll join your project, roll up our sleeves, find all performance bottlenecks, and apply precise optimizations – all by ourselves.
Great when: you don’t want to distract the team from delivering business functionality, and you want to make sure all quirks and implementation nuances are considered.
What: we’ll teach your team everything we know about React performance or Core Web Vitals. We’ll take a slow site, figure out what makes it slow, and gradually fix every performance issue we encounter.
Great when: you want a foundation to make sure your team knows how to keep you fast.

Are you a non-commercial open-source project? Our work wouldn’t be possible without open-source tools. Reach out, and, if we have capacity, we’ll be glad to help for free.
Want something custom? We’ll be glad to chat. Reach us, and let’s figure out how we can help you.
We worked with Google on educating developers about web performance. This targets the long-term goal of making the web faster.
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.
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.
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.
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.
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.
Framer is an interface prototyping product.
We worked with Framer to perfect loading speed of Framer Web, Framer Desktop and Framer Sites.
By working together, we reduced Speed Index and First CPU Idle of Framer Web by 40-45%. We also set up tooling around runtime perf – to help Framer keep & maintain achieved results in the future.
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.
