Nobody had the job title - fractional vibe coder - two years ago. That’s the point.
A fractional vibe coder embeds into your team or business part-time to build, ship, and iterate on digital products using AI tools. No full-time hire. No agency. No freelancer taking a brief and disappearing.
Someone who thinks like a founder, builds like a developer, and charges for outcomes, not hours.
What They Actually Do
A fractional vibe coder sits at the intersection of product thinking and AI-powered building.
They take your idea from napkin to working product. They iterate based on real feedback. They know which tools to use, how to prompt them well, and how to make decisions fast enough that things actually ship.
The building happens through AI tools: Lovable, Cursor, Claude Code. The value is in knowing what to build, in what order, and how to cut scope without cutting the thing that matters.
Why Fractional
Most early-stage founders don’t need a full-time developer. They need someone who can move fast on a few key things, bring product judgment, and get out of the way when the work is done.
Fractional means senior-level thinking without the salary, the equity conversation, or the six-month hiring process.
Why Vibe Coder Specifically
Traditional developers write code. Vibe coders direct AI to write code while staying focused on what the product needs to do and who it needs to serve.
Same output. Faster process. Lower cost. Tighter feedback loop.
Who Needs One
You need a fractional vibe coder if:
You have a product idea and no technical co-founder. You’ve been quoted $30k+ for an MVP and it feels wrong. You want to validate something fast before committing real resources. You’re a non-technical founder who needs to move at startup speed without startup overhead.
This Is What I Do
I’m Nina Kolari. I’ve shipped 6 iOS apps in 6 months, won a solo hackathon against 27 teams, and spent 17 years building businesses from anywhere in the world.
I embed into early-stage teams as a fractional vibe coder, bringing product thinking, AI building skills, and the judgment that comes from actually shipping things to real users.
