One thing I've learned as a product engineer is that a tech stack is rarely the starting point.
The real starting point is the problem.
A common mistake developers make is adopting a predefined stack for every project, regardless of the client's goals, budget, timeline, or maintenance capacity.
Recently, I chose a headless CMS over building a custom backend for a client project.
Why?
Because the client needed a simple way to manage content after launch. A custom backend would have given us more control, but it would also have increased maintenance overhead and long-term complexity.
In another project, I preferred guest checkout over mandatory authentication.
Why?
Because reducing friction during checkout was more important than collecting user accounts. Fewer steps meant a smoother buying experience and potentially higher conversions.
These decisions aren't always the most technically impressive.
But product development isn't about choosing the trendiest stack or building the most complex architecture.
It's about making the right trade-offs for the people who will use, maintain, and pay for the product.
The best tech stack is often the one that solves the problem with the least unnecessary complexity.
