The client, a healthcare software solutions company, wanted to participate in the AWS Migration Acceleration Program (MAP) Assess phase to develop a total cost of ownership (TCO) for migrating a legacy platform from Microsoft Azure to AWS.

This evaluation aimed to understand the long-term financial impacts of consolidating their IT infrastructure on AWS. The client's business drivers for this evolution were cost minimization, enhanced operational efficiency, reduced infrastructure complexity, and harnessing the power of AWS.

As the architect, I conducted discovery workshops to fully understand the client's existing footprint in Azure. I also designed a hub-and-spoke networking architecture that acted as a centralized ingress and egress network access across three regions (US and Europe).

I leveraged services such as Transit Gateway, AWS WAF, Load Balancers, and others for this purpose.

The client wanted to migrate the MLOps Infrastructure responsible for their Recommendation Engine from SpellML to Amazon Sagemaker to support their MLOps practice.

As the Infrastructure/DevOps Engineer, I collaborated with a Machine Learning Architect to design and implement an Amazon Sagemaker infrastructure, including training pipelines and model-serving infrastructure.

The client was a company that produces books, classes, and other materials for outstanding math students and was looking to containerize its workloads in AWS to support a platform application that will enable them to move customers between products easily and accomplish a faster go-to-market time for new products.

As the Architect, I collaborated with an Engineer to review, plan, design, and implement a container orchestration solution in the client's staging environment as a PoC. Our goal was to showcase how they could modernize their platform in AWS.

We also provided guidance and implementation for container monitoring, logging, and CI/CD pipelines.

The client, the largest public electric vehicle (EV) fast-charging network in the United States, wanted to migrate certain web applications from Rackspace and an on-premises data center to AWS.

As the architect, I collaborated with an engineer to review, plan, and perform the migration without service disruption. We chose the Replatforming (lift and reshape) migration technique, which allowed us to modernize the client's infrastructure without altering the core application architecture.

The client, a Brazilian fintech company, wanted to modernize their infrastructure to host a set of microservices consumed by their public-facing applications.

As the architect, I reviewed, designed, and implemented a scalable and secure infrastructure on AWS, using Terraform as the Infrastructure-as-Code (IaC) tool. Additionally, I developed CI/CD pipelines that allowed the client's developers to push changes to the production environment more frequently.

This solution reduced the client's operational costs and increased code deployment frequency by enabling developers to change the code in each environment without requiring an operations person to do it manually.

The client, a Brazilian fintech company, wanted to implement a CI/CD pipeline to allow their developer's team to deploy their code automatically using a GitOps approach.

As the architect, I designed, developed, and implemented a CI/CD pipeline that allowed the client's developers to build the code of their Angular front-end projects and frequently push changes to the production environment running on S3 + AWS CloudFront.

This solution reduced the client's operational costs and increased code deployment frequency by enabling developers to change the code in each environment without requiring an operations person to do it manually.

The client, a Brazilian fintech company, wanted to migrate their infrastructure from an on-premises data center (TIVIT) to a public cloud provider (AWS) using the re-platform migration technique.

As the architect, I first evaluated the technical and financial aspects of several cloud vendors and ultimately chose AWS as the platform. Next, I reviewed their entire legacy infrastructure, designed a multi-account/region/VPC architecture, and collaborated with the engineering team to migrate a set of systems that processed millions of financial transactions daily.

This migration brought order to the client's infrastructure architecture and operations, previously in a state of chaos. As a result of this project, I received an invitation from AWS and Claranet, an AWS partner, to present the migration case at AWS Summit Sao Paulo 2017.
