Hi

I'm Rafał. Welcome to my website.

I'm a software engineer from Poland, and this site is primarily for recruiters and engineers involved in the recruitment process.

I created this site in 2014 to make the recruitment process more efficient. At the time, many job offers I received were either not relevant to my experience or didn't align with my expectations. So, I always asked recruiters to visit for_recruiters page first, where I tried to address the most common questions typically asked in the first phase of interviews.

Over the years, the percentage of recruiters and engineers who visited my page before contacting me has grown from about 10% to 75%, so I believe it serves its purpose.

Some additional numbers

• 300k of concurent players
• $800 per second via payments API
• 15k DB transactions / second
• deploying to 500k MySQL DBs
• 6 years of on-call
• improved games integrations process (the technical part) from ~6 months to 0.5 - 2 days
• most of the frontends I built backend for, were written in React, Vue, Phoenix LiveView and mobile Apps (Flutter, React Native, iOS, Android)
