Experience
AWS Cost Optimization Project
A large enterprise company needed an AWS expert to do cost audits and optimize its cloud expenses. I analyzed their cost structure and over 25 accounts in three different regions and proposed large optimization projects focusing on cost centers and AWS services. We optimized the expense of over 15 different AWS services like EC2, EBS, S3, Athena, RDS, DynamoDB, and more; it involved hundreds of teams and required a lot of coordination to move forward.
Extensive analysis of reserved instances and savings plans were needed, and many purchases were made to optimize the compute resources consumption.
After a semester of work, many services were shut down, rightsized, or adjusted in their configurations, which meant a nearly $1 million reduction in expenses.

Orchestrate CICD Pipeline and Implement IaC
https://www.isic.org/I was in charge of assessing our client's current continuous integration and delivery pipelines, identifying failing points and problematic deployments. Designed new architecture that's resilient and seamless. It allowed the developers to fast-track their release cycles.
I designed a new multi-account landing zone for their AWS resources using the well-architected framework guidelines and deployed the new infrastructure in it. It was all built using Terraform with Terraform Cloud automated pipelines that required no human interaction to deploy the full architecture.
By the end of the project, the client's entire infrastructure and CICD pipelines were in code for ease of use and an easy handover. New environment isolation and GitOps features were added to the developer experience.

IMO—AWS Migration
https://www.imohealth.com/Led a consulting team working for a US-based health services company. The project consisted of migrating more than 200 apps to AWS from on-premises. It involved many months of on-site work in client offices in Chicago and leading a team in three different countries and time zones. Set up the HIPAA-compliant cross-region infrastructure using cloud and security best practices and state-of-the-art tooling to enable continuous delivery and fully automated DR processes.
Fintech—AWS Migration
I assisted a US-based fintech company that was in the process of migrating from on-premises DCs to AWS. I assessed their stack and needs and designed a highly available landing zone in AWS using a well-architected framework. The infrastructure components were created and managed entirely with infrastructure as code, and the app was re-engineered and re-platformed to run on Kubernetes. Everything is deployed through a series of fully automated CI/CD pipelines.
I've also been tasked with cost reduction and reduced up to 60% of our AWS bills by leveraging both Spot Instances and ARM64-based worker nodes on our Kubernetes clusters.

SaaS Platform—Senior Architect
A SaaS for insurance companies needed expertise and advice on cloud best practices. I was the primary engineer assigned to the client, having to review their stack and services. I designed and delivered a well-architected landing zone based on the fundamental pillars of the framework, such as security, reliability, and operational excellence. The ecosystem relied on serverless applications and EC2 static workers. A part of the process consisted of providing continuous integration and delivery to improve the cadence of the development process and ease the operational overhead. Containerizing vital business logic components were key to improving the QA and testing phases and providing high availability and fault tolerance capabilities in key components. Designing a SOC2-compliant infrastructure was an essential piece of the project.
DevOps | NFT Marketplace
A startup about to launch its NFT marketplace needed an experienced DevOps. I was in charge of designing and implementing a resilient environment using best practices in AWS. I've created a multi-account landing zone with a multi-tier, highly available network layout. The applications were re-platformed from ECS to EKS and have been adapted to run on Kubernetes using Helm charts. A deployed cluster for the environment and CICD pipelines were added to each application to continuously build and release the code. Everything was developed using Terraform and best practices to deliver a fault-tolerant, highly available, cost-effective infrastructure.
