Acerca de este Servicio

I build production AI chatbots and RAG systems that actually work from simple Q&A bots to complex multi-agent applications with document retrieval.


What I Deliver

Chatbot Development: LangChain conversation chains and agents. OpenAI GPT-4 / Claude integration. Custom prompt engineering and templates. Conversation memory and context management.

RAG (Retrieval-Augmented Generation): Document ingestion and chunking strategies. Vector embeddings with OpenAI/HuggingFace. Vector databases: Chroma, Pinecone.

User Interfaces: Streamlit chat interfaces. FastAPI backend for production.


Tech Stack: LangChain, LlamaIndex, OpenAI GPT-4, Claude, HuggingFace, Chroma, Pinecone, Weaviate, FastAPI, Streamlit


Background:

  • Built course recommender chatbot using LangChain, Chroma, and OpenAI
  • Created career guidance bot with profile-based recommendations
  • Developed serverless AI proofreader on AWS with OpenAI integration
  • Published ML research on text classification and neural networks (IEEE, Springer)


Use Cases:

  • Customer support chatbots
  • Document Q&A systems
  • Knowledge base assistants
  • Course/product recommenders
  • Internal company assistants
  • Legal/medical document analysis

I build backend APIs and data systems that scale. 5+ years building production systems: FastAPI/Django backends, AWS serverless platforms (10K+ users), async data pipelines, OpenSearch integrations (100K+ docs), web scrapers, and InfluxDB time-series systems with Grafana dashboards. I deliver clean, documented, production-ready code — APIs with proper validation, ETL pipelines with error handling, and infrastructure that doesn't break at 3 AM. Published researcher (Springer, IEEE) on distributed systems. Message me with your requirements — I'll give you an honest assessment.
