What you get:

FAQ
Do I need to provide my own API keys (OpenAI, Claude, etc.)?
Yes. AI usage is billed by the provider to your own account, so you stay in control of costs and data. I'll help you set up the keys and store them securely.
Are hosting and other running costs included?
No, my price covers development only. Hosting, database, domain, and AI API usage are billed by those providers directly to you. Many offer free tiers for early-stage apps.
What do you need from me to get started?
Your project goal, key features, any design references, and preferred tech stack if you have one. Not sure yet? Message me before ordering and I'll help you scope it and pick a package.
What technologies do you use?
Next.js, React, TypeScript, Tailwind CSS, Node.js, Express.js, PostgreSQL/MongoDB, plus OpenAI, Claude, LangChain, and RAG for the AI features.
Do you provide source code?
Yes, full source code is included in every package, and you own it once the order is complete.
Do you help with deployment?
Yes, deployment support is included in every package. I'll deploy the app to your hosting account (for example Vercel) and confirm it works live.
How long will it take?
Basic takes 6 days, Standard 10 days, and Premium 14 days. Larger or more complex projects can be quoted with a custom offer.
Can I request more features later?
Yes. Changes within the agreed scope are handled through revisions, and new features through a custom offer.
How many revisions are included?
Basic includes 2, Standard 3, and Premium 5. Revisions cover changes to the agreed scope. New features are quoted separately.
Can you work on my existing project?
Yes, in many cases. Message me with details about your codebase and what you need added or fixed, and I'll send a custom offer.
