Brokerage dealer interested in algorithmic trading — where should I start if I don’t know coding?

Hi everyone, I’m currently working at a brokerage firm and have experience in product development and operations. Right now I’m working as a dealer.

Market knowledge-wise, I’m quite familiar with trading, but I would like to explore algorithmic trading. The challenge is that I don’t have any coding background.

For someone starting from zero in coding, how should I begin this journey? What basic skills should I learn first, and are there any courses or certificates you would recommend?

I would really appreciate any guidance
