05 / FREQUENT QUESTIONS

Inquiry Solutions

Do you build WordPress themes from scratch or use builder templates?

I develop completely custom, tailormade WordPress themes and plugins from the ground up using clean PHP, responsive Tailwind CSS, and optimized database queries. This keeps code bloat-free, secures your system, and delivers the highest performance.

How do you guarantee a 90+ PageSpeed score on heavy sites?

I perform asset optimizations: minifying CSS/JS payloads, caching server queries, using next-gen image conversions, deferred script execution, and cleaning DB transients. This ensures lightning-fast speeds and satisfies core web vitals.

Can you integrate third-party payment gateways and ERP APIs?

Yes, I have extensive experience setting up secure third-party connections. I regularly integrate Stripe, PayPal, Razorpay, Twilio SMS APIs, custom CRM systems, and database ERP architectures via secure cURL queries.

Do you provide technical support after code delivery?

Absolutely. I provide standard warranty support for bug-fixes and security maintenance for 30 days after deployment. I also offer custom retainers for ongoing optimization and theme updates.
