E-commerce Development for Online Stores and Sales Platforms

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

Online stores selected around the way the business works

I have been building online stores since 2015. I choose the platform based on the size of the catalog, the order process, planned integrations, maintenance needs and budget.

Depending on the project, I work with PrestaShop, WooCommerce or lightweight systems such as Quick.CART. The goal is not to add as many features as possible. The goal is to build a store that works reliably and remains manageable as the business grows.

Performance, checkout and integrations

I pay attention to loading speed, mobile usability, payment security and the purchasing process. When needed, I integrate the store with payment gateways, invoicing, inventory systems, ERP or CRM platforms and courier services.

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.
