Seeking Advice: How to Break Into Ecommerce Development? I will not promote

Hi everyone! 👋 I’m a freelance developer with experience building apps and web apps (like local delivery services and sales platforms), but now I am diving into custom-coded ecommerce websites and want to master building them from scratch. If you’ve worked on custom ecommerce projects: 1. What challenges should I prepare for? 2. What advanced features do clients eventually request? 3. Any tips for balancing security, scalability, and cost? To practice, I’m offering simple custom websites for $900 (no Shopify/WooCommerce, fully custom coded). What I can deliver: ✅Custom product catalog, cart/checkout, user accounts, and admin dashboard. ✅Secure payment integration (Razorpay/Stripe/PayPal/Cashfree) and basic security setup. I guess it would be perfect for small businesses or startups that want a unique site and don’t mind guiding me. I’ll keep communication open, share progress, and welcome feedback! If you have a small project and want a custom solution, you can message me! I’m happy to discuss ideas. P.S.: I am new to Reddit, please let me know if I missed any posting rules. Thanks for your patience!
