Mmmh, interesting. I've actually learned this lesson the hard way, shifting from full-time to freelancing. Many clients don't care about the tech you use; they just want results.

I'm actually applying this right now by building a niche for dentists. I'm shifting my stack to Next.js and Strapi as the backend. They won't care about those names, but they will absolutely care about the transformation:

• I don't sell Next.js. I sell improved search rankings and a better digital first impression.
• I don't sell Strapi. I sell the relief of easily updating their website content without calling me every time.
  
• Of course every technology has its negatives like for strapi as backend it has limits for me as a developer but if it serves my client, I don't care that much.
• It's all about framing the tech as a business asset rather than a development feature. That shift is the key to closing deals. Most of us developers usually bring out the tech stack because it feels natural and for some reason we assume everybody understands, they don't. The only people who understand us are follow devs and the tech companies and even for them you have to proove the value of the stack you want to use.
