Performance improvements
Make your app feel faster.
Slow starts, stuttering screens, and long loading times make an app harder to use. I help investigate where time is being spent and what to improve.
Focus on the experience that feels slow.
Tell me which screen or action takes too long, on which device or browser, and under what conditions. Startup, scrolling, rendering, and loading can require different investigations.
Measure before choosing the improvement.
Useful performance work starts with a baseline for the affected flow. We can agree what to measure and use those observations to identify the changes most relevant to your users.
Compare the result in the same conditions.
A meaningful comparison uses the same devices, data and actions before and after a change. The scope and outcome depend on the app; I don’t promise a percentage improvement before investigating it.
Before we start
Can you improve an existing mobile or web app?
Yes. Performance work is available for existing products. Share the stack and the slow behavior so we can discuss access and scope.
Can you guarantee a perfect performance score?
The goal is to improve the actual user experience. A score or percentage depends on the product, hosting, devices and measurement conditions, so it cannot be promised in advance.
What should I send first?
Send a product link or build, the affected screen or action, and the device or browser where you notice the slowdown. Existing measurements or recordings are helpful if you have them.
Tell me what you’re working on.
Share the product, the problem, or the role you have in mind.
