Gig Summary

Vetted by Fiverr Pro

Safiullah R was selected by the Fiverr Pro team for their expertise.

About this gig

LLM applications engineered for production: RAG pipelines and LangGraph agents with evaluations, guardrails and monitoring, for teams whose prototype works in a demo but not reliably with real users.


What this covers

  • Review of your current LLM, RAG or agent system, with a written list of failure cases
  • Evaluation datasets and automated tests for answer accuracy, retrieval quality and tool calls
  • New build or rebuild with LangGraph, LangChain or LlamaIndex, structured outputs and fallbacks
  • Guardrails, cost and latency tuning, caching and model routing
  • Tracing and dashboards (LangSmith, Langfuse or OpenTelemetry)


How it works

  1. Access to the code and a sample of real queries
  2. Baseline measurement, then each change measured against it
  3. Report, merged code and a handover call


Background

Machine-learning researcher focused on reliable AI (calibration and failure analysis). Top Rated seller and Fiverr Pro in AI and software development, with 100+ completed orders since 2022.


Please message me with a short description of your system and what is going wrong before ordering.

I build AI products that keep working after launch: agents that take real actions, assistants that answer from your own documents, and full-stack AI web and mobile apps. Since 2022 I have completed 100+ orders on Fiverr for clients in 16 countries. My background is research in reliable machine learning (M.E. Mechatronics, medical-imaging AI), so I measure where a system fails before it ships. A small team covers frontend, backend and LLM engineering on larger builds.
