If both strands of the DNA are complementary why complementary codons don’t codify for the same amino acid?

If I read a strand rather than the other I should obtain regardless the same protein, but I checked and the codons are not complementary. So if on a strand I have CGC (alanine) the other should code too for alanine but complementary GCG codes for arginine. Am I missing something?

Don’t forget that you read each strand in a different direction. The ribosomes receive instructions about where and in what way a gene is to be read by promoters and other helpers. It’s the same way you can have multiple proteins be read from the same sequence.
