I will build production ready ai agents and llm apps
Ragavendra S
Acerca de este Servicio
Hi, I'm Ragavendra, founder of FRE|Nxt Labs and InterviewLM (850+ AI assessments delivered).
I build PRODUCTION-READY AI agents, RAG systems, and LLM applications for founders and SaaS teams who need real engineering, not demos that break in week two.
WHAT I BUILD:
AI agents with tool calling, memory, and multi-step workflows
RAG systems over your docs, databases, or APIs (vector search, hybrid retrieval)
AI chatbots with Claude, GPT-4, Llama, or open-source LLMs
Custom MCP servers and LangChain/LangGraph pipelines
Full AI SaaS MVPs (Next.js, FastAPI, PostgreSQL, AWS)
WHY ME:
- 9+ years engineering (ex-Amazon, Groupon, Series A Tech Lead)
- Built and shipped my own AI SaaS (InterviewLM)
- AWS Partner Network member
- Anthropic Claude SDK, Deepgram, LangChain expert
- Production code, not prototypes that leak prompts
Message me before ordering so I can scope your project properly and confirm timelines.

With over 8 years of experience, I specialize in designing and developing scalable, high-performance systems. Currently, as an AI Consultant and Founder at InterviewLM, I focus on leveraging my expertise in Google Cloud Platform (GCP), LangChain, and Langgraph to create innovative AI solutions tailored to complex business needs.
FAQ
What LLM providers do you work with?
I work with Anthropic Claude (my primary, deepest expertise), OpenAI GPT-4 and GPT-4o, Google Gemini, Meta Llama, Mistral, and open-source models via Ollama or Hugging Face. I'll recommend the right model for your use case, cost, and latency requirements.
Do you build production systems or just prototypes?
Both, but my specialty is production. Every project includes proper error handling, logging, evaluation pipelines, and deployment. I've shipped InterviewLM (850+ assessments) and built systems at Amazon and Groupon scale. If you need investor-demo-ready or paying-customer-ready code, I am here
Can you integrate AI into my existing app?
Yes. Most of my work is adding AI capabilities to existing SaaS products (Next.js, React, Python, Node.js stacks). I can integrate via API, build custom MCP servers, add RAG to your existing data, or wrap your APIs with AI agents. Send me your stack and I'll scope it.
How do you handle data privacy and security?
All client data stays in your infrastructure or under your API keys. I sign NDAs (please send yours), follow least-privilege access, and never train models on your data. For sensitive workloads, I deploy on your AWS, GCP or cloud of your choice so you retain full control.
What if my project is bigger than the Premium package?
Message me. FRE|Nxt Labs takes on larger AI engineering retainers and multi-month builds outside Fiverr packages. We can scope a custom milestone-based engagement. Fiverr is great for defined deliverables; for ongoing AI infrastructure work, I'll propose a structured contract.
