About me
I'm a software engineer focused on building reliable backend and cloud systems on AWS.
I work primarily with Python, AWS Lambda, API Gateway, DynamoDB, SQS, SNS, EventBridge, ECS, Fargate, Docker, IAM, VPC networking, Terraform, CloudFormation, and Serverless Framework.
I can help you design and implement serverless APIs, event-driven systems, containerized backend services, AWS infrastructure, CI/CD pipelines, and cloud integrations.
I also work with production GenAI systems including RAG, LangChain, LangGraph, LlamaIndex, model APIs, streaming responses, and tool-based workflows.
