Hi! 1. I’ve implemented multiple RAG systems on Neo4j Vector Search, improving retrieval accuracy through better chunking/metadata. 2. I debug LLM apps by tracing each request end-to-end (inputs, retrieved context, tool calls, output, latency) and isolating the issue to retrieval, prompting/output constraints, model choice, or tool execution. Then I fix the root cause and lock it in with small eval tests plus monitoring to prevent regressions. 3. I’m available for 30+ hours per week. 4. My rate is $20/hour.

@Shaiwan

Hello!!! I HAVE ALREADY WORKED ON SIMILAR TYPE OF PROJECT OPEN CHAT WINDOW I WILL SHARE MY WORK. I have a couple of questions: 1. Which embedding model and vector database are you currently using in your RAG pipeline? 2. Is Vapi handling both STT and TTS, or is it integrated with external providers? What I offer: ⭐ Deep debugging of RAG pipelines using LangChain or LlamaIndex ⭐ Vector search tuning and embedding alignment fixes ⭐ Context window optimization and prompt restructuring ⭐ Voice interruption, timeout, and retry logic correction ⭐ Output validation enforcing clinical template structure ⭐ Clear root cause analysis, tested fixes, and deployment notes I bring 7+ years of experience in Python, AI systems, LLM integration, and debugging production-grade ML applications. My approach: 1. Audit RAG flow, embeddings, and retrieval scoring logic 2. Diagnose voice interaction edge cases and retry handlers 3. Implement structured output validation with test verification Let’s connect and resolve these issues with a systematic fix. Best Regards, Shaiwan Sheikh

@slavkom1

Hi, I’m looking at your Python healthcare app and the mix of RAG issues, Vapi voice bugs, and output validation gaps makes sense. I’ve debugged similar RAG setups with LangChain and LlamaIndex, plus voice flow problems in Vapi, so I know how these fail in real use. I’d focus on clear fixes: - Trace vector search and embeddings to remove mismatches - Tune context window logic for stable clinical responses - Patch interruption detection and silence timers - Repair retry handling after user breaks - Enforce template structure with tight output filters I can start quickly and expect a couple of days to stabilize things. Which part of the RAG pipeline do you want profiled first: embeddings, chunking, or retrieval scoring? Greetings, Slavko

@albertc1996

Hello, I’ve worked on debugging production RAG systems and voice-enabled LLM applications, particularly around retrieval relevance, embedding alignment, and structured output enforcement. My approach to troubleshooting would include: • Auditing embedding generation and chunking strategy • Verifying vector index configuration and similarity thresholds • Evaluating prompt layering and context window allocation • Testing interruption logic and timeout handling in the voice flow • Implementing structured output guards to enforce clinical template format I focus on root-cause analysis rather than surface fixes, and I document all changes clearly for maintainability.

@chiragardeshna

Hi there, I am a strong fit for this project because I have debugged production RAG pipelines and voice-enabled LLM systems where retrieval quality, prompt control, and interruption handling were failing under real user load. I have worked with LangChain and LlamaIndex-based RAG stacks, tuned embedding strategies and chunking logic, implemented re-ranking and metadata filtering, and resolved STT or TTS interruption and timeout issues in Python-driven voice agents. My approach would begin with structured root cause isolation: validate embedding consistency, audit chunking and vector store indexing, trace retrieval scoring, instrument context window usage, and simulate voice interruption flows with controlled test scripts to reproduce failure states. I reduce risk by adding deterministic output validators, enforcing template schemas post-generation, implementing retry guards for interruption recovery, and delivering documented test cases that prove accuracy, stability, and compliance improvements. I am available immediately for focused debugging work and can provide a detailed hourly or fixed proposal once I review your current architecture and logs. Regards Chirag
