Build better MVPs, prototypes and POCs in the AI era.
I help founder-led teams turn rough ideas into testable product versions fast, so you can learn from real users before you commit to full development.
AI made building faster. It did not make product choices easier.
You can generate screens, but still miss the product logic
Teams now ship UI fast, but users still get confused. Not because the interface looks bad, because the flow does not answer what they need to do next.
Ideas get built before they get tested
When roadmap pressure is high, teams skip the fast learning loop. Then expensive development starts before anyone has clear evidence that the concept solves the right problem.
Prototype work and production work get mixed together
MVPs, proof of concepts and prototypes are for learning. Full software projects are for scale and reliability. These are different jobs and should be treated that way.
What product design means in the AI era
It is not only making polished screens. It is framing what should be built, building the fastest test version, watching how people use it, and deciding what is worth taking to full development. I use AI heavily in this work. The judgment stays human.
MVP framing
Define what to test before you build too much
We start by making the idea sharp. What is the core user problem, what is the smallest testable version, and what would count as a useful signal.
- One clear test goal for the MVP
- Scope that fits weeks, not quarters
- Clear assumptions to validate
Vibe coding build
Build prototype and proof of concept versions fast
I build with you in the tools that make sense for speed. Sometimes that is Figma. Often that is code. The point is simple, get something real in front of users fast.
- Prototype or POC in days, not months
- Flow and interaction quality, not only visuals
- Built for learning, not fake click-throughs
Evidence loop
Test with users and tighten the concept
We run lightweight feedback rounds and look at behavior, not opinions only. Then we improve the concept based on what people actually did, not what we hoped they would do.
- Fast user sessions on key tasks
- Clear notes on where users hesitate
- Practical iteration plan for the next build
Handoff to build
When it needs full software, continue with simplified.fi
When the concept is validated and you need full software delivery, architecture, and production implementation, that work is done with simplified.fi.
- Clear split between discovery and production
- Smoother transition from prototype to software
- No confusion about scope or ownership

Frequently Asked Questions
MVPs
Lean versions you can put in front of real users to test demand and usability fast.
Prototypes
Interactive flows for testing core tasks, onboarding, and value communication before bigger build work.
Proof of concepts
Focused test builds that prove whether a technical or product direction is worth scaling.
This service focuses on early product design and fast validation work. When you are ready for full software delivery, production architecture, and long-term implementation, that is done with simplified.fi.
I use Cursor, Lovable, and Claude actively in the work to move faster from idea to testable product. They help with speed and execution. Product judgment, user understanding, and final decisions stay human.
Week 1
We define the problem, scope the smallest meaningful build, and agree success criteria.
Weeks 2-4
We build, test with users, and iterate quickly so you can decide what to scale and what to drop.
We pick one primary metric before we start, for example activation, time to value, or drop-off at a critical step. Then we track before and after each iteration, not just opinions from the room.
You can pause anytime. The work is scoped in clear monthly chunks, so you always keep usable outcomes and documented decisions.
