Hi!

Thanks for visiting this page! I'm a self-employed, classically-trained software engineer behind the 4Comprehension blog. I created parallel-collectors and lead Vavr. You can find me on X/Twitter.

I'm also a former Founding Engineer at @QuesmaOrg, former Lead Architect at @hazelcast, and former Principal at miim.ai.

While I'm a Java Champion, I always choose the right tool for the job.

My heart has always been drawn to helping people rather than corporations. Obtaining sponsors would allow me to dedicate more time to non-commercial activities on my blog, low-budget community events, and OSS projects. At the end of the day, my main occupation is working on software.

Thank you,
Grzegorz
