Frequently Asked Questions
Please share a description of your project — what the app should do, who it is for, any reference sites or apps you like, and details of any existing systems (such as logins or APIs) we need to connect to. The more detail you can provide upfront, the smoother the build will go. You can share everything via the order chat after purchase.
If you want to quickly test an idea or need a simple proof of concept, the Prototype tier is the right starting point. If you need a more complete application with authentication and a backend, choose Standard. If you want a full SaaS platform with chatbot integration, AI model fine-tuning, and a desktop application, the Full SaaS Platform tier covers everything.
Yes. The team works with OpenAI, Gemini, Claude, and LangChain. If you have a preferred model or an existing API key, share those details in the order chat and the integration will be built around your setup.
Yes. All tiers include full source code delivery so you own the build outright and can continue developing it independently or with another team if you choose.
Deployment support means the application is set up to go live, not just run locally. Depending on scope, this covers deployment to Vercel, Cloud Run, or equivalent hosting. Any credentials or environment variables you need to supply will be requested via the order chat.
Once a build or milestone is delivered, you review it and submit your revision requests via the order chat. Each round of revisions covers amendments within the originally agreed scope. Changes that represent new features or significant scope additions may be quoted separately.
The core service focuses on web applications and desktop applications (Premium tier). If you have a mobile requirement, describe it in your brief and the team will advise on what is achievable within or alongside your chosen tier.

⭐ 1,000,000 STAR REVIEW ⭐ Title: "If a million stars existed, they still wouldn't be enough!" This developer is NOT a human; he is a coding monster sent from another galaxy. I've hired many freelancers before, but this guy completely blew my expectations into another dimension. The quality is so unreal that I'm convinced he secretly time-travelled and brought future technology back with him. Delivery Speed: Faster than light. I sent the requirements, blinked once, and the project was DONE. Quality: So clean and flawless that even big tech companies would be jealous. Communication: Smooth, clear, and professional — it felt like talking to a genius AI. GOAT Coder and developer.
Assylkhan is not only a real expert in his field, but also deeply kind and proactive. He had so much patience with me and answered all my questions with an open heart, understanding and professionalism. He delivered really quickly and I could rely on him 100%. I highly recommend having him on your team!
Great+++++
