Common questions

FAQ — PHP Development

Which PHP version do you work with? +

I primarily work with PHP 8.0, 8.1, 8.2, and 8.3. I also handle legacy projects on PHP 7.x and can assist with migration to modern versions.

Can you work without a framework? +

Yes. I can write clean, structured vanilla PHP when a framework is overkill, or when working on existing codebases that don't use one.

Do you handle database migrations? +

Yes. I design and optimize MySQL/MariaDB schemas, write migrations, and handle data transformations for legacy system upgrades.

Can you integrate my PHP app with third-party services? +

Absolutely. Payment gateways (Stripe, PayPal), CRMs, shipping APIs, social logins, email services — I've integrated them all.

How do I get started? +
