Vishnu Viswanath

An AI Developer and Forward Deployed Engineer with a deep focus on building intelligent systems that bridge cutting-edge research with real-world applications.Started my career in data science, but over time I gravitated towards Large Language Models and applied AI. Today, my work revolves around designing and deploying solutions powered by OpenAI APIs, RAG pipelines, prompt engineering, and speech-to-text audio models, as well as document intelligence tools like Azure Document Intelligence and AWS Textract.I’ve built and scaled products across multiple domains - from document extraction systems and OCR-driven workflows to marketing analytics platforms, workflow automation tools, and enterprise-level AI integrations. Along the way, I’ve worked extensively with FastAPI, Django Stack, MongoDB, and AWS, making AI models not just intelligent, but also fast, reliable, and production-ready.What excites me most is the intersection of AI and business impact - transforming complex problems into solutions that save time, cut costs, and fuel growth.Toolkit HighlightsAI & ML: LLMs, RAG, OpenAI APIs, Prompt Engineering, Transformers, LangGraphDocument Intelligence: Azure AI Document Intelligence, AWS Textract, OCR modelsWeb & Backend: Python, FastAPI, Django, HTMX, MongoDB, SQLCloud & Automation: AWS (Lambda, EC2, S3), Workflow AutomationExperimenting fearlessly, and constantly pushing the boundaries of what AI can achieve.
