ABOUT ME
πŸš€ From Business Needs to AI-Powered Solutions | GenAI & RAG Expert
πŸš€ From Business Needs to AI-Powered Solutions | GenAI & RAG Expert

I help businesses and developers leverage the power of Generative AI, RAG (Retrieval-Augmented Generation), and Agentic workflow to build cutting-edge AI applications. With hands-on experience across Azure AI, OpenAI, AWS Bedrock, SageMaker, and Databricks, I specialize in designing and optimizing AI/ML solutions tailored to real-world challenges.

What I Bring to the Table
βœ… RAG & Multimodal RAG – Designing intelligent retrieval-based AI systems, optimizing embeddings, and leveraging vector databases.
βœ… LLM Integration & Fine-Tuning – Experience with OpenAI, Claude, Mistral, and other open-source & proprietary models.
βœ… Guardrails & AI Safety – Implementing security layers, prompt filtering, and bias mitigation in GenAI applications.
βœ… Agentic Workflows – Building multi-agent AI architectures for automation, knowledge retrieval, and decision-making.
βœ… Enterprise AI Deployment – Expertise in cloud-native AI deployments using Azure, AWS, and Databricks.
βœ… AI Evaluation & Optimization – Fine-tuning RAG pipelines for better accuracy, latency, and cost-efficiency.

Industries & Use Cases
πŸ“Œ Conversational AI & Chatbots
πŸ“Œ Knowledge Management Systems
πŸ“Œ AI-Powered Search & Document Intelligence
πŸ“Œ AI for Finance, Healthcare, Manufacturing, and Automation

πŸš€ Whether you're looking to optimize an existing AI pipeline or build an AI-powered product from scratch, I can help you navigate the complexities of Generative AI and LLM-based systems.

Let’s build something intelligent together! πŸ’‘

- Led end-to-end design and development of enterprise-grade Retrieval-Augmented Generation (RAG) solutions, including document parsing, chunking, vectorization, and semantic search using OpenSearch and Amazon Bedrock.
- Architected and deployed a scalable GenAI pipeline on AWS, utilizing S3, Lambda, SQS, DynamoDB, and VPC to ensure secure data processing and model inference within a private cloud environment.
- Implemented robust guardrails for RAG-based chatbots, including prompt-level moderation, fallback mechanisms, and domain-specific response constraints to ensure reliability and safety in enterprise use cases.
- Integrated advanced agents (smol-ai/smol-agents) into existing RAG infrastructure to enable autonomous task execution and multi-step reasoning with tool-use capabilities.
- Provided technical leadership across GenAI initiatives, mentoring cross-functional teams, optimizing vector search performance, and driving adoption of best practices in prompt engineering, and evaluation.
