Make your site faster → earn more

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

We worked with Framer to perfect their user experience – by making user interactions smoother and app loading faster.

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.

We made Castor’s React design system load and execute faster.

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.

With Appsmith, we did not one but 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.

Common wanted to improve their marketing ROI – and reached to us to help make their website faster. We jumped in and improved the PageSpeed Insights score from 39 to 75.

Working with Ivan was an absolute joy. He reliably produces world-class work, communicates effectively and often, and is always willing to share his deep expertise in application performance optimization.

Fat Llama had issues with page loading performance. They successfully improved a lot of things themselves, but reached to us before finishing the optimization.

We helped Fat Llama to find low-hanging (and not so low-hanging) fruits that went unnoticed – and improve performance metrics even further.

Ivan gave a ton of extremely useful, actionable feedback that directly improved our First Meaningful Paint, Time to Interactive, Speed Index, First CPU Idle metrics significantly. Also, he helped with some bundle size optimization too.

Interaction with Ivan is dense in terms of knowledge transfer, and I guarantee you that you will learn a lot of new things. On top of all these, he’s a super smooth person to work with. All in all, I cannot recommend Ivan enough!
