At NVIDIA, led the design and delivery of a multi-project, petabyte-scale serverless analytics platform aligned with the company’s vision for a secure, scalable Data Analytics Web Application. Architected a cloud-native solution leveraging Amazon EMR, Glue, Redshift Serverless, S3, Lambda, EC2, ALB, and SSM, deployed within a corporate-managed VPC to meet strict security and compliance requirements. All services operated in private subnets with VPC endpoints and were secured using CloudFront, REST APIs, TLS encryption, AWS WAF, Shield, Secrets Manager, and KMS. Designed and integrated a Nuxt.js SSR frontend with AWS Lambda to enable server-side rendering and dynamic API workflows, supporting enterprise SSO via Entra ID (Azure AD) using OAuth 2.0 and OIDC, with server-side JWT validation. Implemented end-to-end observability using Grafana, CloudWatch, CloudTrail, and EventBridge, alongside fine-grained IAM governance through scoped roles and Service Control Policies. Led DevOps automation using Terraform, mentoring and guiding offshore engineering teams to standardize secure, repeatable AWS deployments. Enabled seamless interim environment and website creation using CloudFormation and ECS Fargate per merge request to support rapid feature validation. Provided strategic AWS advisory leadership on architecture design, security posture, and cost optimization, including TCO modeling, budget planning, and forecasting using Cost Explorer, Budgets, and Pricing APIs, ensuring alignment with enterprise analytics delivery goals.
During a Business Venture Trial, I conceptualized, designed, and developed my portfolio website, www.13techs.com, using Next.js, TypeScript, and Tailwind, with Well-Architected Framework principles. I utilized AWS Terraform for infrastructure as code, integrated CI/CD pipelines via GitHub for streamlined deployments, and implemented robust security measures using Lambda@Edge, ACM, and IAM roles for access control, with CloudFront managing CDN distribution. DynamoDB and AppSync/GraphQL facilitated real-time visitor interactions and likes counts, while Brotli and GZIP compression techniques were applied to optimize performance. I successfully reduced monthly costs by leveraging AWS Free-Tier services and budget monitoring. A significant focus of this project was enhancing customer engagement, achieved through the creation of an AI-powered chatbot using Langchain, HuggingFace’s all-MiniLM-L6-v2 embeddings, and Google's gemma2-9b-it LLM. This personalized chatbot, backed by a Lambda-based API, provided real-time, interactive user experiences. Currently, I am working on AI-driven recommendation and inference systems using generative AI, tools, and agents, expanding my expertise to develop innovative solutions focused on business applications and user engagement.
