Making a healthcare site feel fast for patients

Outcomes

• Shippedcode-splitting, lazy loading and caching against Core Web VitalsVerified

The problem

populardiagnostic.com is the entry point for patients looking up services and booking. Slow loads on mid-range phones over Bangladeshi mobile networks cost real appointments.

What I did

• Led a performance push using code-splitting, lazy loading, caching and render optimisation.
• Measured against field Core Web Vitals on the devices patients actually use.

Constraints

• Mid-range Android devices on variable mobile connections
• Content-heavy pages driven by non-technical editors

Stack & tools

• React
• Tailwind CSS
• Core Web Vitals
