My experience includes high-load systems, browser games, admin panels, online stores and learning applications. My main interests are Laravel, custom PHP, APIs and complex business logic.

FAQ

Before we start

Can you work with an existing product?

Yes. I can review an existing application, improve features, connect services and provide ongoing support.

Do I need a technical specification?

No. Describe your users, goal and current process. We can turn that into a scope and implementation plan.

Can we work through written communication?

Yes. Requirements, progress updates and feedback can be handled in writing.

How is the price determined?

After reviewing scope, integrations and priorities. The budget field is an indication, not a quote.
