Linux, DevOps and Web Platform Performance

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

Linux, DevOps and web platform performance optimization

Projects involving Linux servers, caching, Cloudflare, Varnish, deployment automation and web platform performance optimization.

I configure and optimize environments based on Debian, Nginx, Apache, ISPConfig, Varnish and Cloudflare. My work also covers caching, deployment automation and Core Web Vitals. I look for the actual source of the problem instead of limiting the solution to installing another plugin.

Depending on the project, I analyze the application code, database queries, caching layer, external services and server configuration. This makes it possible to improve not only benchmark results, but also the stability and long-term maintainability of the entire environment.

From infrastructure to CMS integration

I work both on server configuration and on solutions that connect infrastructure with WordPress or Craft CMS. This includes Varnish Cache for ISPConfig 3, cache and preload automation for Craft CMS, static file versioning and performance optimization for existing web platforms.

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.
