Aritra Ghosh

ML Engineer with 3+ years shipping AI systems that run in production — not just prototypes. I help businesses automate manual work, build smart APIs, and integrate LLMs like GPT 4o/Sonnet 4.6 into real products.

What I can build for you:
• AI powered backends FastAPI on AWS for text classification, image analysis, or document processing
• RAG chatbots that answer questions from your own data — PDFs, databases, websites
• Migrate older ML models to LLM based solutions to cut infrastructure cost
• Automated reporting pipelines: SQL queries → PDF reports → dashboards
• Speed up slow Python code and optimize MySQL databases

Tech stack: Python, FastAPI, OpenAI/GPT, LangChain, ChromaDB, AWS, MySQL, TensorFlow, PyTorch.

Past work includes audience segmentation classifiers, retail vision APIs, and GenAI reporting systems serving live traffic.
