▪ Contributed to 6+ AWS projects, handling full deployments, infrastructure setup, and CI/CD workflows using GitHub Actions
across test and production environments.
▪ Familiar with REST API concepts (HTTP methods, request/response models, JSON, status codes), worked on integration with
AWS services (API Gateway)
▪ Deployed an LLM-powered knowledge-graph extraction and ideation system using Claude 3.5 Sonnet on AWS Bedrock to turn
documents into graph data and generate insights. Also worked on an AI-powered SRE assistant where I tested, debugged, and
improved prompts. This included using AWS Bedrock (Claude models), LangGraph, and LangChain to build a small multi-agent
system with semantic search, tool calling, and RAG for incident resolution and knowledge management.

such as IAM rules & policies, API Gateway, S3, SQS, SNS, Lambda, CloudWatch alarms, EC2, ECS, ECR, RDS, and
CloudFront.
▪ Improved the reliability of a Kubernetes + AWS project by adding unit and integration tests in Python, practicing TDD, and using
advanced pytest features (mocking, patching, parametrization, fixtures, decorators) to increase test coverage and catch regressions
early.
▪ Built and containerized microservices using Docker, and deployed AWS Lambda functions as container images.
▪ Strengthened DevOps processes by automating CI/CD pipelines in GitHub Actions for both Python and infrastructure code,
including automated tests and Terraform plan checks.
▪ Configured AWS Lambda, CloudWatch, and SQS for asynchronous processing pipelines to improve scalability and reliability for
data ingestion workloads.
▪ Worked with databases on RDS, including experience managing Aurora MySQL backups by creating and exporting snapshots,
extracting MySQL data, and downloading full SQL dump files.
▪ Currently preparing for the AWS Certified Developer – Associate certification (registered for the exam in Jan 2026) to deepen my
cloud-native development and DevOps automation skills.
