What I'm looking for

I'm looking to build production-grade AI-enabled backend systems for large-scale products, especially RAG applications, LLM integrations, document processing solutions, and distributed platforms.

I've built scalable backend platforms across Ascendion, Paytm, Kosh, and Granalyze Technologies, using Python, Django, Flask, FastAPI, Kafka, SQL, and cloud services.

At Ascendion for ZS Associates, I built an AI-powered medical document summarization solution with OpenAI GPT, integrated a healthcare training-document chatbot, and deployed Dockerized Selenium scraping workloads to Azure Function Apps. I also led the AFM project independently across development, deployment, monitoring, and maintenance.

At Paytm and earlier roles, I delivered POS and authentication systems, Kafka integrations, ETL pipelines, REST APIs, payment gateway integrations, and database performance improvements. I'm focused on production-grade AI-enabled backend systems, including RAG applications, LLM integrations, and multi-agent systems.
