Finding a team that actually understands scalability is the hardest part. When we launched our e-commerce platform, we made the mistake of hiring a cheap freelancer, and the code was an absolute mess when traffic started growing. My biggest piece of advice is to ensure whoever you hire builds on a clean, modular framework so you can add features later without breaking the site. We eventually transitioned to a dedicated web development agency<.a> to rebuild everything from scratch. It cost more upfront, but having a solid infrastructure for API integrations saved us so much head scratching later on.
