I will build an ai saas web app with openai api integration

AI SaaS platforms, chatbots trained on your documents, AI features inside an existing web app, and internal tools that summarise, extract or classify data. Backend in Laravel or Node, frontend in React, Vue or Next.js, with a dashboard showing usage and cost.

Yes. I build retrieval augmented generation: your PDFs, docs, spreadsheets or web pages are chunked, embedded and stored in Pinecone or pgvector, so answers come from your content instead of guesswork. You can upload new files any time and the bot updates itself.

OpenAI GPT, Claude, Gemini and open models through OpenRouter or Ollama, plus Whisper for audio and vision models for images. I keep the model layer swappable, so you can switch provider later for price or quality without paying for a rewrite.

I estimate token cost per user action before we build, then cut it with caching, smaller models for simple steps and usage limits per plan. You get an admin view of spend, plus Stripe billing with credits so heavy users pay for what they actually consume.

Yes. I work with existing Laravel, PHP, Node, React and WordPress codebases and add AI through isolated services and REST APIs, so nothing else breaks. I start with a read only review of your repo and a short written plan before anything touches production.

One AI feature or chatbot takes 5 to 10 days; a full AI SaaS with billing usually runs 3 to 6 weeks in milestones you approve. Message me before ordering with your idea or a sample of your data. I reply with a feasibility check, scope, timeline and fixed quote.

Yes. Your files, prompts and outputs stay in your own database and storage, I use API endpoints that do not train on your data, and access is limited by role. If you prefer nothing leaving your infrastructure, I can run open models on your own server.

You get ongoing support after handover. I fix bugs in the delivered scope, tune prompts that drift and hand over source code, environment notes and a short walkthrough so your team can run it. Features outside the agreed scope are quoted separately.

Yes. I work in milestones, so you review each part and request changes before we move on. Small tweaks inside the active milestone are included; anything outside the agreed scope gets a clear price and timeline first, sent as an offer you approve.
