Six Roles, One Founder: What Solo AI Development Actually Looks Like
When building Kvalty.cz, I'm not just a developer. I'm a tech lead, art director, PM, QA tester, brand manager, and copywriter. Here's how the split actually works.
“Solo founder” is a slightly misleading term in 2025. When I’m building Kvalty.cz, I’m not alone. It’s more like a constant meeting between me and AI.
But who actually does what?
Most people think AI writes code and that’s it. The reality of development is much more varied. I had to learn to switch between these roles:
Tech Lead & Code Reviewer
This is where AI does the most work. Churning out code, proposing features. My role? Gatekeeper.
I watch code quality, architecture, and security. AI is a powerful engine, but I have to make sure the machine doesn’t fall apart under the pressure of new features. I often spend time refactoring what AI “quickly” produced.
Art Director (UI/UX)
Visuals are a dance. I come with the vision and wireframes. I try to guide AI toward the right style.
But sometimes I give it free rein: “Design me a component for the driving school detail page.” And sometimes it surprises me with a solution I wouldn’t have thought of. It’s a dialogue, not a dictate.
Product Manager
Here, the human rules. AI can’t see inside users’ heads.
I watch analytics, read feedback, and decide WHAT gets built. AI is then my “Solution Architect” — helping me figure out HOW to technically implement it in a way that makes sense.
QA Tester
AI is an incurable optimist. It usually claims “everything will work.”
Reality? Not so much. What if a user enters nonsense? What if the API goes down? Testing and finding holes is purely on me. AI fixes bugs, but finding and replicating them — that’s my job.
Brand Manager
Here, AI is (still) blind.
Sensing tonality, emotion, and brand trustworthiness? That’s a purely human discipline. Knowing what the product is about at its core and how it should affect people — no algorithm will figure that out for me.
Copywriter
I’ll be completely honest: even my LinkedIn posts are written with AI help.
But it’s not like I say “write a post.” I provide the thoughts, context, and direction. AI polishes it. I iterate and finalize. For Kvalty.cz, I even had to create a “Brand Voice” document. Without it, AI kept sliding into boring corporate phrases.
The Bottom Line
Working with AI doesn’t mean you stop working. It means AI is your engine, but you hold the steering wheel. From the first line of code to the last word on the website.
