What I'm looking for

I'm looking to build secure, reliable cloud and backend systems, including production GenAI applications, with strong attention to observability, least-privilege access, deployment, failure behavior, and cost.

I've built and maintained backend services and AWS infrastructure for we45's security learning platform, supporting reliable hands-on cloud security sandbox environments and real-world infrastructure assessments.

At ShopSwap, I designed cost-efficient serverless architectures, private-networked ECS workloads, distributed NestJS microservices, and scalable PostgreSQL and DynamoDB data models. I also built LLM-powered applications and RAG pipelines using LangChain, LangGraph, and LlamaIndex with attention to secure access, token efficiency, and reliable responses.

Earlier, I delivered GraphQL APIs and AWS infrastructure at Preparie and API-as-a-Service solutions, CI/CD pipelines, and CloudFormation deployments at Bottle Technology. Across my work, I focus on least-privilege access, failure behavior, observability, deployment, and cost.
