About Me

I write custom WordPress plugins for awesome people.

Having worked as a developer on large PHP web apps and tweaks to WordPress sites, I know how to write code that is clean, extensible and reliable using current best practices.

  • ROLE
    Software Engineer
    PHP, React, design patterns, WordPress plugin development

My primary focus is back-end development, most of the time in PHP – the language that powers WordPress. With years of experience as a full-stack developer, I am also fluent on the front-end and I am familiar with React and modern tools and technologies.

I put an emphasis on keeping the code I write clean utilizing proven software design patterns. Software architecture is a subject I am strongly interested in.

I am also proficient in writing automated tests for the code that I write to make sure it is as reliable as possible.

After work, I enjoy making music and I am currently working on building my knowledge in the field of music theory. My instrument of choice is the bass guitar.

    Waclaw Jacek is the best developer I have worked with—hands down. He is responsive, thorough with details and communication, and writes the cleanest code I've seen thus far. He's gone the extra mile for the projects we've worked on, and I can't wait to work with him again soon. Thank you, Waclaw!

    Waclaw was incredible to work with. I absolutely couldn’t have hoped for a better expert or outcome. He took care of my most pressing issue (which had stumped my original website developer), practically before our project even began. He then handled my very long and ever-evolving wish-list of improvements and tweaks to my site. I am not tech-minded and had very limited time to dedicate to the project, which became overwhelming for me, but Waclaw kept everything on track, organized, and laid out so I didn’t lose sight of any of the pieces. He handled everything in stride with patience, professionalism and talent. Waclaw is the ideal codeable expert: a tech ninja, with impeccable communication skills. I couldn’t be happier and recommend him with the highest regard.
