Experience

Site Reliability | Custom Health Monitor for Nike.com

A cutting-edge site health monitor for Nike.com that increased operational intelligence and profitability. I designed and built a custom business intelligence application that collated data from disparate sources in the Nike ecosystem to generate advanced KPI metrics to identify issues on Nike.com.

Also, I oversaw the architecture design to support the application and chose an event-driven architecture hosted on Kubernetes.

The front end was developed using React, Redux, D3.js, and TypeScript, and for the back end, I used TypeScript, Apache Kafka, and DynamoDB. Also, I managed infrastructure using Terraform.

AWS Infrastructure and Data Pipelines for a Fintech Company

Delivered custom AWS infrastructure and data pipelines to support compliance requirements for the company's managed funds using Amazon Athena, AWS Glue, Amazon S3, and AWS Lambda. I used Terraform to provision all infrastructure and GitLab CI/CD to automate deployments.

Sole Retriever | CI/CD and Infrastructure

Designed and developed CI/CD pipelines and upgraded the company's AWS infrastructure to manage its scaling issues. Besides driving the migration from AWS Elastic Beanstalk to Kubernetes with custom autoscaling, I also fixed a major memory leak that plagued their app for weeks.
