Product Builder
From scoped idea to shipped product. I own the entire build using AI-assisted development. You do not manage a single developer or review a single pull request.
Why founders choose Product Builder
One person. Full accountability
No dev team to manage. No communication chain to maintain. One person owns the build from scope to launch and is accountable for the outcome.
AI-assisted means faster and in-budget
What a four-person agency team would take six months to build I can deliver in half the time at a fraction of the cost. Zenpost is the proof.
You stay in the loop without being in the weeds
Weekly demos and updates. You see progress constantly. You never wonder what is happening because I show you.
Scope discipline built in
I built the scope document. I know exactly what is in V1. I protect the project from additions that would delay the launch because I designed the boundaries.
The build starts with the scope. Not the code.
Before anything gets built I make sure we both agree on exactly what is being built. Feature list. User flows. V1 versus V2 definition. Technical architecture. This is the work most agencies skip because they are eager to start billing for development. I do not skip it because a wrong build costs everyone more than getting the scope right upfront.
I did not learn this from a course. I built a production platform solo and it is live right now.
Zenpost is an AI-powered marketing platform with a website builder, social media scheduler, blog editor, CRM, email tools, booking pages, and lead capture. I built it solo using AI-assisted development in 8 months. It runs in production today.
A traditional agency would have quoted 18 to 24 months and $500K or more for an equivalent build.
That is the methodology I bring to every client engagement.
Every engagement has a finish line. On purpose.
The last week is the handoff: written guidelines, a workshop with your team, and a 30-day check-in. Then I'm gone, and your team owns the work without me in the loop.
I don't sell drift. If you need a full-time leader after we wrap, I'll help you find them — that's part of the deal, not a separate engagement.
“Dave is amazing! Super easy to work with and an effective collaborator, taking complex problems and developing successful tech solutions.”
How a Product Builder engagement runs.
- 01
Discovery call
30 minutes to understand what you are building and whether the scope and budget are realistic.
- 02
Scope and architecture
Before any code gets written we align on exactly what is being built. Feature list. User flows. V1 definition. Technical stack. You sign off before I start.
- 03
Weekly build demos
Every week you see what has been built. Real working software, not mockups. You give feedback. I adjust. No surprises at launch.
- 04
Scope discipline throughout
Every feature request gets evaluated against the agreed V1 scope. Good ideas that are not in V1 go on the V2 list. This keeps the launch date real.
- 05
Launch and handoff
When the product meets the agreed launch criteria I deploy it, document the codebase, and deliver a 30-day post-launch support window for bugs and adjustments.
Is a Product Builder right for you?
This is for you
- You have a validated idea with a clear scope and you want it built.
- You do not want to manage a development team yourself.
- You want to move faster and spend less than a traditional agency would charge.
- You are comfortable with AI-assisted development as the methodology.
- You have a realistic budget for the build and want it spent efficiently.
This is not for you
- You do not have a defined scope yet (start with Product Consultant).
- You want to hire a team and manage them yourself.
- You need enterprise-level security certifications like SOC2 or HIPAA on day one.
- You expect daily availability and round-the-clock communication.
- You are not willing to hold the V1 scope once we have agreed on it.
Questions about this engagement.
What does AI-assisted development actually mean?
I use tools like Cursor and Lovable to build faster than traditional development. AI handles the repetitive work. I handle the architecture, the decisions, and the quality. The output is real production code, not a prototype.
Is AI-built code reliable enough for a real product?
Zenpost runs in production with real users. That is the answer. The code quality depends on the developer using the tools, not the tools themselves.
Do you do What happens if the build takes longer than estimated? than three months?
Scope is agreed upfront. If the build runs longer because of scope changes you requested that is a separate conversation about timeline and cost. If it runs longer because I underestimated the work that is my problem to solve, not yours.
Do I own the code when it is done?
Yes. All code, all repositories, all assets are yours at delivery. I retain no rights to anything built for you.
What tech stack do you use?
It depends on what you are building. For most web applications I use modern React-based frameworks with Supabase for the backend. I choose the stack based on what will serve the product best long term, not what I am most comfortable with personally.

Every engagement is scoped. Pick the one closest to where you are.
Product Consulting
You have an idea or a problem. I turn it into a clear plan with a scope document, realistic budget, honest build recommendation. Everything a dev team needs to build it correctly.
Product Lead
I embed into your project as your technical co-founder. Product strategy, development team leadership, and roadmap execution without the full-time hire.
