High-traffic AWS Infrastructure

http://broadwayworld.com
TASK DESCRIPTION:

I handled the AWS architecture, deployment, and maintenance of the world's largest theater and live entertainment website serving several million visitors a month in multiple geographies and languages.

TASKS ACCOMPLISHED:

• Migrated the whole infrastructure from scattered VMs to AWS using AWS DataSync and Migration Service.
• Improved systems resilience by introducing a reliable autoscaling setup with Application Load Balancer, all supported by AWS Lambda functions.
• Introduced continuous integration and delivery (AWS CodePipeline, AWS CodeCommit, AWS CodeBuild, AWS CodeDeploy).
• Architected and deployed Postfix-base high-volume mail cluster to improve deliverability while keeping costs in mind.

Cost Optimization on the Multi-tenant eCommerce Platform

I continuously tried to reduce AWS costs on multi-tier multi-tenant eCommerce systems used by many large UK retailers.

TASKS ACCOMPLISHED:

• Implemented AWS Trusted Advisor and cost management services to understand AWS costs better and CloudWatch to get more in-depth insights into utilized AWS services.
• Reviewed existing resources.
• Implemented saving plans or reserved instances where possible.
• Implemented spot instances as a part of auto-scaling groups.
• Monitored resource usage and types and made adjustments when necessary.
• Performed an S3 replacement with colder storage for less frequently used data types.
• Reviewed bandwidth.
• Made auto-scaling adjustments for MySQL and NoSQL databases for less overallocation and following traffic patterns.

Test Automation on an eCommerce Platform

I spearheaded test automation across the company and used Ghost Inspector as the first layer of acceptance tests. I also introduced acceptance and unit tests to the eCommerce platform while working with third-party consultants. Finally, I implemented a robust solution to run them across the environments with the EKS-hosted Selenoid cluster. I collaborated with team leads and developers to ensure the sustainability of the change.

Continuous Integration and Delivery Improvements

I used Bitbucket pipelines for AWS Lambda functions and Jenkins pipelines for a new branching process. I also set up CI/CD, which streamlined the release process and improved the scalability of Jenkins slaves. Finally, I introduced build monitoring via HipChat with Sumo Logic and configuration versioning on Bitbucket, giving teams better visibility over deployments.

PCI Compliance

I was an integral part of the team tasked with achieving PCI-DSS Level 1 compliance an eCommerce platform. I moved to microservice, which completely isolated the payment system. I also implemented systems hardening and built a new log management system. Finally, I compiled extensive documentation. All of the above allowed us to breeze through QSA assessments and penetration tests.

Development Environment

I improved the production team's productivity and remote working capabilities by making and coordinating multiple improvements to the development environment and tooling. I also experimented with a trial of three technologies: Vagrant with Chef-managed VMs, Docker, and OpsWorks-managed Cloud9. Finally, I used Docker as a primary local working environment with Cloud9, mostly for remote work.

Sumo Logic Log Management

I spearheaded improvements to our log management tooling to reduce maintenance burden and complexity, meet PCI compliance, and improve host metrics. This increased teams' productivity—a better UI, LogReduce, and LogCompare—and resulted in a 30% cost reduction from ELK and a 600% data retention increase.

Multi-region AWS Infrastructure

I architected and implemented an AWS infrastructure split into multiple regions—Dublin, Tokyo, and Northern California—with cross-region data replication for MySQL, Elasticsearch, and Memcached. I extensively utilized SNS and SQS for cross-region communication and latency-based routing on Route 53 with health checks, resulting in a much improved latency and reliability for clients worldwide.

Subscriptions

I provided technical leadership to the team that created a product that reduced support for retailers who have reported "20 inquiries per day to virtually zero since launch." These payments made use of continuous authority on numerous payment providers.

Amazon Pay

I led the technical implementation, delivery, and project coordination of the beta pre-launch of Amazon Pay's multicurrency solution on the platform while providing valuable technical input to Amazon's team on their APIs and SDK.

AWS Service Catalog Provisioning System

A robust service catalog system allows users to provide required resources without hassle using a custom interface. I built CloudFormation templates to ensure they were suitable for the company's needs allowing options that were in line with the company's policy and cost optimization good practices.
