Low-risk first step
Half-Day Technical Diagnostic
$400–$800 · half day
One focused question, a senior technical review, and a written next-step plan
Bring one concrete iOS, macOS, architecture, performance, sync, App Store, or on-device AI problem. We review the relevant material, work through it together on a call, and turn the result into concise written recommendations.
- • Pre-session review of the relevant code or product context
- • Focused working call
- • Written findings and prioritized next steps
- • Clear scope if follow-on implementation is useful

How Engagements Work
Clear expectations, senior execution, no surprises.
Fixed scope. Documented changes.
Deliverables are defined upfront. Out-of-scope changes are reviewed and agreed before implementation.
Direct work with a senior engineer.
No project managers, no juniors, no handoffs. You work directly with me.
Async-first communication.
Updates via email/Slack. Live calls only when needed for technical alignment.
Long-term product thinking.
Code architected for evolution. Clear trade-offs documented. No technical debt shortcuts.
Project Fit
These engagements work best for specific teams and scenarios.
Good fit
- •Funded startups building their first iOS app
- •Privacy-first products needing on-device processing
- •Complex data-driven apps requiring solid architecture
- •Teams needing senior-level execution without hiring
- •Validated product with clear decision maker
Not a fit
- •Marketing websites or simple content apps
- •Unbounded full-build requests without a defined scope
- •Template customization or white-label solutions
- •Projects requiring 24/7 support or immediate turnaround
- •Unpaid speculative work or open-ended discovery
Common Questions
Can I start with a smaller paid engagement?
Yes. The Half-Day Technical Diagnostic costs $400–$800 and focuses on one product, architecture, performance, or implementation question. It includes a working session and written recommendations.
How much does an Apple platform architecture audit cost?
$1,500. Delivered async over 5 days with one live review session. You receive a prioritized roadmap, architecture assessment, and AI readiness evaluation.
What's included in the MVP Sprint?
Full SwiftUI architecture for iOS or macOS, a Core Data or SwiftData persistence layer, CloudKit sync configuration where appropriate, and an App Store–ready build. $9,000 over 4–5 weeks. Fixed scope, fixed price.
Do you work with non-technical founders?
Yes, if the product problem is defined. Technical decisions are explained in plain terms. You will understand what is being built and why — without needing to read Swift.
What happens after the MVP Sprint?
The codebase is yours, fully documented. A retainer for ongoing development or support is available on request. No lock-in.
Can I start with an audit before committing to a build?
Yes. The Architecture Audit is designed exactly for this — evaluate the technical approach before committing to a full build engagement.
Ready to Start?
Start with a half-day diagnostic or describe the implementation work you need. A short email is enough.
