Product Engineering Sprints
From $6,000 / 2-week sprint
Fixed sprint pricing · Focused outcomes · No daily tracking

From $6,000 / 2-week sprint
Fixed sprint pricing · Focused outcomes · No daily tracking
What’s included
Sprint scope is defined upfront. If we need more time, we book another sprint — no hourly billing.
MVP Development
From $12,000
Scoped & quoted · Fixed timeline · Definition through launch

From $12,000
Scoped & quoted · Fixed timeline · Definition through launch
What’s included
Minimum engagement is $12,000. Every project is scoped and quoted based on the feature set, so you know the exact cost before we start.
Full Product Build
From $15,000
Scoped & quoted · Milestone-based

From $15,000
Scoped & quoted · Milestone-based

Larger builds run on milestones, so payment tracks delivery rather than time.
Fractional CTO
From $6,000/month
3-month minimum · Cancel anytime after · No long-term lock-in
Perfect for post-MVP startups who need senior architecture without a $200k/year full-time hire. I provide clearer technical decisions, stronger architecture, and keep your engineering team unblocked.
From $6,000/month
3-month minimum · Cancel anytime after · No long-term lock-in
What’s included
Priced on leadership and ongoing availability, not by the day.
How the work actually runs
01
Understand
We discuss the idea, product, users, goals and constraints.
02
Define
We clarify scope, priorities, architecture and the best path forward.
03
Build
The product gets designed and engineered for quality, usability and maintainability.
04
Launch & Improve
It goes into users’ hands and iterates on real-world feedback.
Why work together
Product thinking, engineering and architecture in one person
Most builds fail in the gap between what a founder pictures and what an engineer delivers. Here there is no handoff across that gap — the same person scopes the product, designs the architecture and writes the code.
