Summary

AI/ML Engineer focused on designing and building production-grade AI systems.
My work centers on integrating machine learning models into backend systems, with emphasis on reliability, scalability, and real-world deployment.

I specialize in LLM-based applications, retrieval-augmented generation systems, and backend architecture for AI-driven products.


Core Expertise

  • Applied AI Systems (LLM applications, RAG pipelines, prompt orchestration)
  • Backend Engineering (REST APIs, system design, service integration)
  • Retrieval Systems (semantic search, embeddings, document QA)
  • AI Workflows (automation pipelines, structured reasoning systems)
  • Model Integration (ML models in production environments)

Technical Stack

Languages: Python, C/C++

Backend: FastAPI, Flask, REST APIs

Databases: PostgreSQL, MySQL

Machine Learning & Deep Learning: PyTorch, TensorFlow, Scikit-learn

LLM & Retrieval: Hugging Face, LangChain, LangGraph, FAISS

Tools: Docker, Git, MLflow
