Hey there! 👋
My name is Wacław Jacek and I am a Senior+ Software Engineer with 18 years of professional experience.
If you would like to learn more about my career, I invite you to check out my LinkedIn profile. For a brief summary of my most recent past, I spent my working hours:
Engineering shipping and payments at WooCommerce
I spent the past 4.5 years at WooCommerce (Automattic) working on the company's flagship shipping and payments offerings: WooCommerce Shipping and WooPayments, as well as Woo's entire shipping product suite.
Having gained tons of experience working on shipping in ecommerce, I became one of two founding members of a re-established shipping team, working closely with leadership to establish a new product strategy, leading cross-functional initiatives, and managing key partner communications, including leading the integration of WooCommerce Shipping with the top 1 shipping carrier in the United States.
Freelancing
I worked closely with clients on projects big and small, spanning from completely custom web apps to WordPress and WooCommerce plugins and website builds.
Working as a Certified Expert at Codeable, I achieved an average rating of 5/5 based on 102 completed projects.
Here are some of my favorite reviews from my fantastic clients:
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. [...] I couldn't be happier and recommend him with the highest regard.
The best developer I've ever worked with!
