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

I help businesses, engineering teams, and developers design, optimize, and unblock high-performance Generative AI applications. With a focus on turning experimental AI into deterministic, production-grade software, I provide direct architectural mentorship and hands-on debugging to streamline your platform workflows.

Whether you are scaling a multi-agent system, resolving high infrastructure costs, or troubleshooting complex backend pipelines, I help you eliminate bottlenecks across cloud-native environments.

🎯 WHERE I CAN UNBLOCK YOU IMMEDIATELY:

  • Agentic Workflows & Orchestration: Multi-agent state machine design using LangGraph, handling long-running state persistence, tool calling, and autonomous self-correction loops.
  • RAG & Multimodal Search Architecture: Advanced data engineering pipelines, vector database optimization, semantic caching implementation, and real-time document intelligence layers.
  • Secure Text-to-SQL Pipelines: Setting up reliable text-to-SQL logic, schema-mapping techniques, and robust enterprise guardrails to ensure precise execution.
  • Enterprise AI Safety & Guardrails: Implementing custom validation layers, dynamic prompt routing, rate-limiting, and evaluation suites to measure accuracy, latency, and cost-efficiency.
  • End-to-End Cloud-Native Engineering: Scaling production microservices using Python and FastAPI, managing distributed systems architecture, and optimizing P95/P99 latency bounds.

🚀 USE CASES WE CAN ACCELERATE TOGETHER:

  • Highly reliable conversational AI systems and advanced chatbots
  • Intelligent enterprise knowledge management and AI-powered document search
  • Automation tools and deep analytical analytics architectures for complex data environments

If you are trying to optimize an existing production pipeline, transition a proof-of-concept (POC) to a secure enterprise framework, or need real-time debugging assistance on Python or LangGraph stacks—let's connect and get your code unblocked.

- 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.
