I am a seasoned software architect with 19+ years of experience in software design and system development, specializing in AI‑driven automation and cloud‑native architectures. Over the last 5 years, I’ve focused on AWS Cloud technologies including Amazon Connect, Lex chatbots, Lambda, Python, Terraform, SQL Server, and serverless, event‑driven systems. My expertise includes building intelligent, LLM‑powered workflows with AWS Bedrock (amazon.nova‑micro), Lex, and Retrieval‑Augmented Generation (RAG) for scalable process optimization. I design prompt‑engineered, schema‑aware solutions that reduce redundant code, improve efficiency, and deliver measurable business outcomes. ### Key Contributions: - **AWS Bedrock/Nova + Lex Integration**: Integrated LLMs into Lex chatbot flows via Lambda for prompt‑driven AI logic, automated validation, dynamic response generation, and workflow orchestration — reducing redundant Lambda code and improving operational efficiency. - **ServiceNow Automation**: Orchestrated ServiceNow API calls via Lambda + Step Functions for automated ticket creation. - **Secure API Development**: Built REST APIs and configured API Gateway for scalable, serverless integration with robust error handling and logging. - **LLM‑Powered Data Analytics & Visualization**: - Designed pipelines using Vertex AI Gemini models to generate SQL queries from prompts and BigQuery schema. - Executed LLM‑generated SQL against BigQuery, validated results, and transformed datasets into Matplotlib charts. - Automated chart export and storage into Cloud Storage via Cloud Run with error handling and IAM‑secured workflows. - **Agentic AI Architectures**: Prototyped multi‑agent and admin‑agent orchestration frameworks, enabling autonomous collaboration between specialized agents for complex workflows. ### What I Deliver: - Seamless customer engagement with Amazon Connect + Lex chatbots - Scalable automation using AWS Lambda & serverless architectures - AI‑enhanced workflows with Bedrock/Nova, Vertex AI Gemini, LLMs, and RAG - End‑to‑end analytics pipelines with secure, automated outputs - Agentic AI frameworks with multi‑agent orchestration for enterprise‑grade automation If you’re looking for a reliable expert to architect, implement, or optimize AI + cloud solutions, I deliver high‑quality, production‑ready results tailored to your business needs.
