About this gig
Need an AI-powered web app built properly not just a ChatGPT wrapper?
I build full stack AI web applications using Next.js, Django, and RAG architectures that are production-ready, secure, and actually shipped to real users.
What I can build for you:
- AI chatbots and LLM-powered assistants
- RAG pipelines with vector search (Pinecone, Embeddings, PgVector)
- AI document processing and PDF parsing workflows
- SaaS platforms with subscription billing (Stripe, Paddle, Square etc)
- REST APIs, WebSockets, and Server-Sent Events
- Authentication systems (JWT, OAuth 2.0, session-based)
- AWS, Docker, K8S, Google Cloud, Railway deployment
My stack:
- Frontend: Next.js, React, TypeScript, Tailwind CSS
- Backend: Django, FastAPI, REST APIs, Celery, Redis
- AI: OpenAI API, Ollama, LangChain, RAG, Pinecone, LM Studio
- Database: PostgreSQL, MongoDB, Elasticsearch, Redis
I have shipped a live AI-powered SaaS platform covering 100+vuniversities across 5 European countries, built RAG-based testvgeneration tools, and integrated LLM features into production
e-commerce systems.
Every delivery includes clean code, documentation, and a handover call.
Message me before ordering I confirm scope within a few hours.

FAQ
Are you available for full-time or part-time work on my project?
Yes, this would be even great as I look for long-term opportunities.
Do you work with existing codebases?
Yes. Share your repo before ordering and I will review it and confirm scope within few hours. I have extended and refactored existing Django and Next.js codebases for previous clients
Which AI models do you work with?
OpenAI, Gemini, Claude and also open-source models via LM Studio and Ollama for clients who need on-premise or cost-efficient setups.
What is a RAG pipeline and do I need one?
RAG (Retrieval-Augmented Generation) lets your AI answer questions based on your own documents or data instead of just general knowledge. If your app needs accurate, source-based answers, you need RAG. Message me and I will advise.
Do you handle deployment?
Yes. I deploy to AWS, Google Cloud, Azure, Railway, Vercel, Cloudflare or Render depending on your requirements. Domain setup, SSL, and environment config are included.
Can you integrate with my existing tools or APIs?
Yes. I have integrated Stripe, Paddle, QuickBooks, TaxJar, Elasticsearch, and more. Share your requirements and I will confirm compatibility before you order.
Will I own the source code?
Yes. Full source code ownership is transferred on completion. I can also sign an NDA before project discussions if required.
How do you handle project communication?
I provide updates at key milestones and respond within a few hours during working hours. For larger projects I share a brief scope document before starting so we are aligned from day one
What if I need changes after delivery?
Revisions within the agreed scope are included per package. For changes outside scope I provide a fixed quote before proceeding - no surprise costs.
How do I get started?
Message me with a brief description of your project - what it does, your stack if you have one, and your timeline. I will respond with questions or a scope outline within a few hours.
