Experience
Ai Engineer
May 2025 — Present
Working on building Agent in the domain of Agentic AI for USA Healthcare surgery center Company.– Developed an AI agent using the AGNO Agentic Framework. I used models such as OpenAi-oss-120b,LLaMA3.3 70B, Claude 4.1 Opus, DeepSeek R1, etc, to generate SQL queries from natural language input andexecute them against an AWS PostgreSQL database. During evaluation, I found Claude to be more accurate,correct, and less prone to hallucination.– Implemented a caching mechanism to store the database schema for faster query generation, instead offetching it from AWS for each query, which reduced latency.– Connected the frontend (HTML) and backend (FastAPI) using Socket.IO to enable real-time responses.– Enabled conversational memory for continuous conversation, with all conversations stored in the AWSPostgreSQL database.– Enabled the agent to handle and display query results dynamically as pie, line, or bar charts, tables, and text,with advanced high-quality analytics and suggestions based on user intent. Added an intelligent error-catchingmechanism and deployed it on the Sigmatic.ai website.
