This is an excellent discussion on building future-proof products. In my experience, the biggest challenge isn't just the technology itself, but maintaining an architectural flexibility that allows for the seamless integration of new models and features without a full rewrite. During our work at ion301, we tested various approaches and found that a modular, API-first design from day one was a game-changer for long-term scalability. Have you also found that focusing on the foundational architecture early on is the key to avoiding future technical debt?
