You've identified an area of math where, despite many books, it's difficult to find one that isn't too abstract.

Below are a couple of personal favorites:

1) In keeping with the numerical theme of this forum, A. David Wunsch's book: "A MatLab® Companion to Complex Variables" is all about calculating with complex numbers. While written as a supplement to other textbooks (including Wunch's own "Complex Variables with Applications" - find a less expensive used 1st or 2nd edition), it stands fairly well on its own. Open-source GNU Octave can be used to do the calculations or it might be fun translating commands to 15C or 42S RPN or to RPL.

2) Some of the most practical examples of complex analysis can be found in the complex variables chapter of (old) books on Laplace transforms, e.g., "Introduction to Laplace transforms for radio and electronic engineers" by W. D. Day - a vacuum tube era book using British notation (p instead of s for the transform variable) but with a nice graphical example of complex integration.
