I will develop ai integrated web and mobile applications
Abdul Haseeb
About this gig
Want to build an intelligent, next-generation AI web or mobile product?
Off-the-shelf wrappers aren't enough. Modern AI products require fast streaming interfaces, optimized vector search, secure server-side API handling, and scalable full-stack code.
I develop custom AI-powered web applications and mobile apps using Next.js, React Native, Node.js, and modern LLM APIs (OpenAI, Anthropic, open-source models).
What I Build:
- End-to-end AI web platforms and cross-platform mobile apps (iOS & Android)
- Custom RAG pipelines for chatting with private documents/databases
- Real-time token streaming and responsive chatbot UI
- Autonomous AI agents, task automations, and structured JSON outputs
- User auth, Stripe subscription payments, and database architecture (MongoDB/PostgreSQL)
- Zero-downtime deployment with complete source code ownership
Why Work With Me?
- Production-first engineering with low latency and clean architecture
- Secure API key management and token-cost optimization
- Clear communication and structured progress updates
Please message me to discuss your AI product concept and scope before ordering.

I’m Haseeb, a Full Stack and AI Engineer specializing in building scalable web applications and intelligent AI solutions. I bridge the gap between robust web architectures and modern AI systems. Whether you need a custom RAG chatbot trained on your company data, seamless OpenAI/LLM API integrations, or high performance web platforms using Next.js and the MERN stack, I deliver secure, production ready code tailored to your business goals.
FAQ
Can you build both the web platform and the mobile app for the same AI product?
Yes. Under the Premium package (or a custom offer), I build a Next.js web application and a companion React Native mobile app (iOS & Android) powered by the same backend API and shared user database.
Which AI models and tools do you support?
I integrate OpenAI (GPT-4o, embeddings), Anthropic (Claude), open-source models via Groq or HuggingFace, and vector engines like Qdrant, Pinecone, or Supabase pgvector.
How do you keep API token costs low and prevent abuse?
I implement server-side rate limiting, context window truncation, semantic caching (via Redis or vector thresholds), and input validation to keep external API costs strictly controlled.
Do I need my own OpenAI / LLM provider account?
Yes. You provide your own API credentials so billing stays under your control and your data remains private. I guide you through the setup process if required.
Will I own all the source code?
Yes, 100%. You receive complete source code, deployment configurations, environment file templates, and instructions to run and manage the product.
