Put a senior engineer behind your AI app for five focused days. I inspect the code, infrastructure, data flows, and launch controls—then tell you what can break and exactly what to fix first.
Fixed scope. Five business days.Leave with a launch decision: ship, fix first, rebuild the risky parts, or move into ongoing support.

Most requests move to a meaningful milestone within a few business days. Larger work is broken into smaller releases so progress stays visible.
We start with a 30-minute fit call. The production-readiness review creates the shared map of your codebase, risks, and highest-value next steps.
Demari does. There are no account managers, hidden subcontractors, or handoffs to junior developers.
No. Add as many requests as you need to the shared queue. I work through one active priority at a time.
The membership is month-to-month. Pause before the next billing cycle when you do not need an active engineering slot.
Yes. Larger work is broken into clear, shippable milestones. If the project needs a full delivery team, I will say so before we start.
The service is best suited to modern web products, including JavaScript and TypeScript applications, React and Next.js, APIs, cloud infrastructure, databases, and common deployment platforms.
Changes move through your existing development workflow. I add tests and review gates where needed, document the release, and keep a rollback path for production changes.
Active clients get a private workspace with a shared request queue. Add context, links, screenshots, or acceptance criteria, then choose the highest priority.
Say so early. I will clarify the requirement, explain the tradeoff, and revise the active request before moving to the next priority.
Yes. Large greenfield builds, around-the-clock on-call coverage, and work that requires a full delivery team are scoped separately.
Start with the fixed-price production review or book a call. A monthly membership is best when you have an ongoing queue of engineering responsibility.
Try the ownership membership for one week. If it is clearly not the right fit, you can receive 75% back—no drawn-out process.
Yes. There is no long-term contract. Keep the membership while it is useful, then pause or cancel.
