I am an Agentic AI Architect and Generative AI Engineer specializing in designing intelligent systems powered by Large Language Models, Retrieval-Augmented Generation (RAG), and multi-agent orchestration frameworks.
My work focuses on building production-ready AI systems that can reason, retrieve knowledge, and autonomously perform complex workflows using modern LLM infrastructure.
I design Agentic AI architectures where multiple AI agents collaborate to solve business problems such as:
• Intelligent knowledge assistants
• Autonomous workflow automation
• AI copilots for enterprise systems
• RAG-based research and analytics tools
• Multi-agent decision systems
I have deep experience building end-to-end AI pipelines, from knowledge ingestion and vector indexing to multi-agent orchestration and deployment.
My expertise includes building AI systems that combine LLM reasoning with structured knowledge sources such as vector databases, knowledge graphs, APIs, and enterprise data platforms.

I help founders, CTOs, and engineering teams design, troubleshoot, and deploy AWS systems using Lambda, API Gateway, ECS/Fargate, Cognito, RDS, DynamoDB, S3, CloudFront, CloudWatch, CDK/Terraform, IAM, and CI/CD pipelines.
You should contact me if you need help with:
✅ AWS architecture review before launch
✅ Cognito authentication and user-management setup
✅ EC2, Load Balancers, Firewalls, VPC, and secure networking
✅ Serverless APIs with Lambda, API Gateway, DynamoDB, SQS, SNS, and Step Functions
✅ ECS/Fargate deployments for containerized apps
✅ CI/CD, infrastructure as code, and repeatable deployments
✅ AWS cost, security, IAM, VPC, and observability improvements
✅ Rescue work when an AWS setup is broken, unstable, or hard to maintain
In my enterprise career, I have led AWS cloud practices, delivered large-scale cloud programs, trained teams, and worked across architecture, DevOps, backend systems, and cloud governance. On Upwork, I focus on hands-on, practical AWS work for small teams that need senior help for 5–20 hours per week.
Clients value me for clear communication, structured problem-solving, and building systems that are secure, maintainable, and cost-aware.
I am especially useful when you need someone who can both design the architecture and get hands-on with implementation.
