• Reduced AWS spending 65k (82%) per month by rearchitecting infrastructure (AWS Lambda, API Gateway, Aurora RDS, CloudFront, Terraform, PHP, Python, DynamoDb).
• Develop, host and maintain Django and Fast API Python applications using AWS Lambda and Kubernetes
• Manage and deploy AWS infrastructure using Terraform
• Configured APMs (New Relic, SigNoz) for enhanced visibility, debugging, and troubleshooting
• Improved security by configuring automated security monitoring (AWS Security Hub) across AWS accounts to help identify security weaknesses, then fix critical issues
• Identified and solved scaling problems by building a load testing tool, updating AWS infrastructure and SQL optimization. (AWS Aurora RDS, AWS Lambda, Redis)
• Drove adoption of GitOps with ArgoCD and Kubernetes
• Designed and implemented a framework to decouple the company's integration code from the main platform codebase which decreased integration cost and increased overall product quality (AWS ECS, Aurora RDS, Terraform, Python)
• Manage AWS and GCP/Google Admin Accounts
• Built and maintain all code pipelines (AWS EC2, GitLab, Bash, Terraform)
• Configured VPN and AWS SSO for AWS accounts to improve security
• Implemented async PHP worker queue (AWS SQS, Lambda)
• Identified inefficient or missing organizational processes and worked with team members to find good solutions for all parties
• Trained, pair programmed, and mentored junior developers and engineers, teaching skills in AWS, Python, JavaScript, React, Terraform, SQL and working to improve overall team performance.
• Worked with project managers, developers, quality assurance and customers to debug, troubleshoot and resolve technical issues.

Building a planning application leveraging AI (LLM) and prompt engineering to generate recommendations which improve and organize plans for gatherings with medium to large complexity. This project is used to learn new technologies outside of work.

• Designed inheritance structure and development pattern for Idaho Power developers to refactor charts
  and accessibility tables across Idaho Power's public website ( JavaScript, JQuery, Highcharts, Lodash, PHP, Wordpress, Gulp, GIT, CSS preprocessors )
• Designed and implemented a stored procedure comparison test application to generate all possible
  parameter values, compare procedure outputs, and write test results to excel files. Because I wrote it
  generally, there are plans to use it in future projects. ( C#, ASP.Net Core 2.0, T-SQL, SQL Server, SSMS, LINQ )
