What I'm looking for

I seek cloud-focused roles where I can design secure, automated AWS architectures, improve operational reliability, and grow in infrastructure and ML/AI practices within collaborative teams.

I am an AWS-certified Solutions Architect and Cloud Practitioner with hands-on experience designing scalable, secure cloud architectures and automations using AWS services.

My background spans systems administration, data analysis, QA, and scripting with Linux and Bash, which I combine to optimize operations and improve reliability.

I have implemented solutions across industries—financial services, healthcare, serverless applications, ML/AI integrations, and data analytics—using EC2, Lambda, RDS, DynamoDB, SageMaker, CloudFormation, and security services.

I am passionate about automation, security, and efficient cloud architecture and I seek to contribute to teams focused on operational excellence, scalability, and secure cloud migrations.
