Core Web Vitals Optimization for MODX Site
Budget: $30 – $250 USD
Title: Improve INP to <200ms on MODX site (Core Web Vitals Optimization)
Description:
We are looking for a frontend performance expert to help us optimize INP (Interaction to Next Paint) on our MODX-based website. The goal is to bring the homepage INP below 200ms so that it falls within the green zone of Core Web Vitals.
Important Context:
We are aware that MODX has architectural limitations. Many low-level performance techniques are not available out of the box, such as:
* Async/defer control over 3rd-party scripts
* Custom asset bundling or tree-shaking
* Inlining critical CSS
* Advanced lazy-loading or priority hints
* Performance profiling for layout shifts or long tasks
We've already tried minor performance tweaks and custom code, but the INP is still not improving significantly.
Your Task:
* Analyze the current INP score and identify the most realistic improvements possible within MODX limitations
* Optimize JS execution, reduce long tasks, and improve responsiveness of interaction events
* Defer non-essential scripts, reduce render-blocking behavior
* Minimize DOM complexity if applicable
* Provide a short performance audit report (before/after)
Budget: \$195 (fixed)
Requirements:
* Experience with Core Web Vitals (especially INP, TBT)
* Proven track record of improving interaction responsiveness
* Comfortable working within MODX limitations
* Able to explain what's feasible and what's not
If you understand the limitations and believe you can realistically improve INP under 200ms — apply with your plan of action.
