Veelgestelde vragen
Do you only build AI features, or can you handle the full SaaS platform?
Both. I can integrate a single OpenAI feature into your existing app, or build the entire SaaS platform from scratch — including auth, database, billing, and cloud deployment. Message me with your current situation and I'll scope the right package.
How do you keep OpenAI API costs under control at scale?
I implement token budgets, prompt caching, streaming responses, and usage monitoring dashboards so you're never surprised by API bills. I also optimize prompts specifically to reduce token count without sacrificing output quality.
What's RAG and do I need it?
RAG, lets your AI answer questions using your own data — documents, databases, PDFs — instead of just general knowledge. If your product involves any kind of 'ask questions about our content feature, you need it. I'll tell you honestly during scoping if it applies to your use case.
Can I see examples of your AI SaaS work?
I've built enterprise AI search tools, document intelligence platforms, and financial AI applications for US-based clients. Due to NDAs I can share sanitized screenshots and architecture diagrams — just ask in the message.
What tech stack do you use?
Frontend: React / Next.js. Backend: Python, Node.js / Express / TypeScript. AI: OpenAI API, Lang Chain, Llama Index. Databases: PostgreSQL, MongoDB, Pinecone / pgvector. Cloud: AWS (EC2, Lambda, S3) or GCP. I match the stack to your requirements, not the other way around.
Will I own the code and IP after delivery?
Yes. Full source code, documentation, and complete IP transfer to you on final payment. I'm happy to sign an NDA before any technical details are shared — just request it in the message.
What if my idea changes mid-project?
Minor scope changes within the same feature set are handled at no extra charge. Significant pivots (new AI features, new integrations) are quoted separately before any work begins — you'll never get a surprise invoice from me.
Do you handle deployment and hosting, or just hand over the code?
Both. All packages include deployment to your cloud environment (AWS, GCP, or your choice of provider). I set up CI/CD, environment variables, and production configs — you get a running product, not just a code repo.
How long does it take to build an AI SaaS MVP?
A focused MVP (core AI feature + auth + basic UI + deployment) typically takes 10–14 days. Complex platforms with RAG, multi-tenancy, and payments take 18–21 days. I confirm exact timelines during the free scope call before you order.
I'm non-technical. Will I understand what you're building?
Absolutely. I send weekly plain-English progress updates, explain architectural decisions in simple terms, and deliver a handover document written for non-technical founders. Many of my best clients are non-technical — you don't need to understand the code to own the product.

The delivery is outstanding for this price and time. Mr Myasir Khan got a copy that was used on the app store (3 pages of text in a pdf), and some screenshots and managed to string all that together into a very nice product page that is just minor tweaks from a deployment. I'm happy to see how Khan has really put though into placements of texts and images.
