Plans for 2026

• I’ll keep on looking for ways to improve the newsletter anyway possible :) With every year, there are additional things that I add or make improvements to the newsletter.

• I am writing a book with O’Reilly → you are now the first one to know, outside of my close friends and family :) The plan is to publish it in 2026, and I’ll be making an announcement about it soon. Excited to share more details about it!

• Do a pre-recorded video course of the Senior Engineer to Lead: Grow and Thrive in the Role course. Stay tuned for that!

• I have many other initiatives in mind, including a possibility of additional course, more podcast-type style videos, and I would like to do a live conference/event someday as well.

• Keep on attending and speaking at conferences, as I enjoy them a lot!
