I will build production grade agentic and rag applications
Karthikeyan TS
About this gig
Hi! I'm Karthikeyan. I build production RAG and agentic AI systems that work with your real documents, records and databases not generic chatbots or demos that break the moment real data shows up.
You brief me on the problem. I design, build and deploy the system on your infrastructure, then hand it over 100% of the code and accounts are yours. No lock-in, no retainer.
WHAT I BUILD
- RAG systems, end to end ingestion, retrieval, reranking, citations, evaluation
- Agentic AI multi-agent orchestration, tool calling, memory, autonomous workflows
- Private assistants that answer from your internal docs and databases
- LLM integration into your existing product, API or database
- Custom AI apps backend architecture through production frontend
TRACK RECORD
- Multi-agent engine for a startup open-ended questions on company data, 6-8s, fully offline
- RAG assistant over a large recipe dataset for a fitness community
- Journal platform (100+ weekly users) and a community events platform (1,000+ members), both live
- National Finalist, NSCIF 2026
Best fit: teams losing hours searching documents, or AI experiments that aren't reliable enough for real users.

FAQ
Do I own the code?
Yes, all of it, on every package. I build on your infrastructure and accounts wherever possible, and hand over the full repo plus documentation at the end. No lock-in, no hosting on my side, no retainer required.
