Acerca de este Servicio

Is your AI application slow, broken, or giving poor results? I'll fix it.


I debug and optimize RAG systems, LangChain agents, and LLM applications. Whether you have retrieval issues, API errors, slow performance, or accuracy problems I can help.


WHAT I FIX:

Poor search accuracy, slow vector lookups, chunking problems, memory leaks, integration errors, API failures, prompt issues, outdated dependencies, incorrect metadata handling.


TECH STACK:

LangChain, LlamaIndex, Chroma, Pinecone, FAISS, Weaviate, Qdrant, OpenAI, Anthropic, Claude, Llama, Ollama, FastAPI.


YOU GET:

- Working code with all fixes applied

- Explanation of root causes

- Performance benchmarks (if needed)

- Optimization recommendations

- Clean documentation


BEFORE ORDERING:

Message me with your setup details: tech stack, error logs, what's not working. This helps me scope the work accurately and give you a realistic timeline.


I have QA testing background I don't just patch bugs, I find root causes.

I build production-ready AI features: LLM-powered apps, agents, and automation for real business workflows. What I can help you with: LLM chatbots with tool use, structured outputs, and guardrails. AI agents that search, reason, and take actions. RAG systems with vector databases (FAISS, Chroma, Pinecone). FastAPI backends for AI services. Data extraction and ETL pipelines. Dockerized deployment. My portfolio includes a Self-Initiated Research Agent and an AI Business Knowledge Assistant, both built end-to-end. I'm reliable, communicate clearly, and deliver working code.
