How to find first freelance clients as a Web & Shopify Developer?

Hi everyone,

I'm a web developer with hands-on experience in frontend technologies (HTML, CSS, JavaScript) and Shopify development—including theme customization, store setup, catalog management, and troubleshooting.
I'm looking to build up my freelance workflow and secure more projects. For experienced freelancers and agency owners here:

1. What platforms or outreach strategies worked best for you when starting out?

2. How do you usually approach small business or store owners to offer custom dev work?

Any advice, resources, or tips would be greatly appreciated!
