Paweł Potacki case studies: WordPress, Craft CMS, e-commerce, Linux and DevOps

Quick.CART w prostszych sklepach z jasno określonym katalogiem

Quick.CART zapisuje dane w plikach zamiast w tradycyjnej bazie SQL. Może być dobrym wyborem przy mniejszych sklepach, które nie potrzebują rozbudowanej logiki, wielu integracji ani skomplikowanego zaplecza.

Nie jest rozwiązaniem dla każdego projektu. W odpowiednim zastosowaniu pozwala jednak zachować prostą obsługę, małe wymagania serwerowe i czytelną strukturę.

Tell Me About Your Project

I usually reply within 24 hours

What You Can Expect When Working with Me

A good project starts with understanding the real problem. Before I write any code, I review the requirements, look at the current setup and suggest an approach that makes sense for the business, the budget and the expected scale.

Security and stability from the beginning

I think about data protection, maintainability and failure prevention before development starts. These are part of the architecture, not fixes added later.

Performance matched to the project

I optimize the code, database and server environment according to the way the system will actually be used. This includes everyday traffic, seasonal demand and predictable spikes during campaigns or product launches.

Clear communication

I explain the technical decisions in plain language. You know what is being built, why a particular solution was chosen and what alternatives were considered.

How We Work Together

I do not treat projects as an assembly line. I work on a limited number of implementations at a time so I can stay involved in the details and make sensible technical decisions throughout the process.

1. Initial Review

You describe the project, the current problem or the planned changes. I review the requirements and usually reply within 24 hours with initial feedback, follow-up questions and an estimated scope of work.

2. Architecture and Scope

Before development starts, we define the scope and select the right tools. Depending on the project, this may include WordPress, WooCommerce, Craft CMS, PrestaShop, custom PHP development, external integrations or Linux server configuration.

3. Development and Deployment

I handle the implementation, testing, deployment and performance tuning. After launch, I can also take care of updates, monitoring, further development and server maintenance when ongoing support is needed.
