At Publicis Sapient, I designed and deployed an enterprise AI Assistant for an IT Data Control platform, grounding answers in more than 15K documents. I built its RAG pipeline with pgvector, hybrid retrieval, and real-time index synchronization.
I designed LLM routing with tool and function calling, plus a custom evaluation framework using golden datasets, regression tests, and LLM-as-a-judge scoring. I cut latency by 80% through parallel calls, streaming, and caching, and added production observability.
At ClickPost, I built a Python and Django dispatch management system handling more than 30K daily dispatches, improving efficiency by 40%. I also built background processing for refund transactions and a webhook fallback that reduced transaction failures by 90%.
Earlier, at Wipro, I developed Python APIs and data-processing tools, and implemented pytest test suites. I work across Python backend development and production GenAI applications, using tools including FastAPI, Docker, Kubernetes, AWS, and Azure.
