FAQ

Before you reach out

How do you charge — hourly or fixed?
I prefer working on a fixed-scope basis. We define deliverables, timelines, and budgets beforehand, so you know exactly what you are paying for with no hidden fees. If a project is highly experimental or undefined, we can start hourly at $35/hr until the scope solidifies.
What does a typical project cost?
For a mobile MVP (built to ship), the typical budget starts from $3,000. AI-based audits or rescue services start at $300. Every project has a clear, written estimation with a fixed number before any contract is signed.
How long does it take?
A typical MVP takes between 4 to 8 weeks depending on complexity. Audit and rescue projects are much faster—usually delivered within 3 to 7 days.
How do payments work?
We start on a 50% upfront payment to lock in the timeline and scope. The remaining 50% is due upon completion and delivery. Payments are accepted via Wise or Payoneer. If you prefer escrow protection, we can run the contract through Upwork.
Do you take small projects or fixes?
Yes! If you have a broken app, need a performance audit, or want to integrate an AI/LLM agent, I can jump in. My AI app rescue package ($300 audit) is designed exactly for this.
What happens after launch?
You get 30 days of free support to resolve any bugs. If you need ongoing maintenance, feature updates, or server monitoring, we can set up a monthly support retainer starting at $1,500/mo.
Who owns the code?
You do. Absolutely. Once the final invoice is paid, all intellectual property rights and codebase access (GitHub/GitLab repos) are transferred to you. No hostages, no hidden contracts.
Do you sign NDAs?
Yes, I regularly sign NDAs before any sensitive project details or designs are shared. Your intellectual property and confidentiality are fully protected.
