Forget about your front-end performance problems.
I’ll take care of them.

Hi, I’m Ivan Akulov, a consulting front-end developer.

I can help you optimize your front-end app or site to make users more satisfied and increase your conversion:

Why performance is important

Slow apps earn less. As Aberdeen Group learned, slowing down the page loading by 1 second leads to 7% loss in conversions.

+1s in loading time is −7% in conversions

Slow sites get lower in the search results.

Users dislike slow apps. Up to 40% will abandon a website if it loads in more than several seconds.


I’ve helped several projects:


Optimized size of the Polished library, dropping it from 16 KB to 7.9 KB (in my setup). Case study

That is awesome! Thank you for putting in that work

51% smaller

A major Eastern European hosting provider

Analyzed a hosting panel and explained how to decrease the loading time by approximately 60%. We’ll implement the improvements soon. Case study

60% smaller

I can help you too

I offer two options:


to fix a specific problem.

I’ll analyze and solve your particular performance issue – as well as I can. If your app loads slowly, or some pages don’t work fast enough, this is for you.

If I’m unable to solve the issue, I’ll return you the money.


to constantly keep the app fast.

Once per month, I’ll analyze your app and fix all the performance issues I can find. If you want to never think of your app’s speed, this is for you.

To make this reliable, we’ll define specific performance budgets (loading time or app size), and I’ll keep the app inside them.

The first three months are paid together in advance.

In every option, I work with the loading performance of your app + rendering performance of app pages.

Currently, I focus on apps and sites written with React or without a framework. That’s my primary expertise.
