Taggify is a full-stack programmatic digital out-of-home (DOOH) platform that dynamically servers ads on outdoor screens. High availability is essential because every second offline loses money.

I designed Taggify's architecture using the microservices approach. Then I coded all the infrastructure in Terraform and Helmfiles. Finally, I deployed it to Amazon EKS and AWS RDS using GitOps. As part of the stack, I installed Argo CD for syncing the cluster to the desired application state.

Taggify also provides white-label SasS, so data isolation was required at all levels. The Terraform script supports deploying the additional infrastructure necessary for these new clients.

A "Mobile Application Starter Kit" with two parts: The "Application Kit" was created using React Native, and the "Backend Kit" was done with the Serverless Framework. I was in charge of all the DevOps aspects of the project. For the Application Kit, I used Fastlane for building and signing, Firebase App Distribution for deploying QA versions, the App Store for the production version, and GitLab pipelines for automating every step.

A stake pool I created for the Cardano blockchain, using Terraform for the infrastructure and Ansible for setting up Ubuntu on the relays and the master node. The stack can be monitored using a Grafana dashboard that includes every KPI of the blockchain.

Lamason is a SasS that provides managed WordPress and WooCommerce websites. The company also hosts hundreds of eCommerce websites, so it needed a cost-effective and secure hosting solution and an easy way to deploy new sites.

I used Terraform to deploy Kubernetes and the additional services, including AWS ALB Ingress Controller, Amazon EFS and EBS controllers, Prometheus, and Grafana. I also created an optimized POD that used a combination of Amazon EBS and EFS for better performance and to support horizontal autoscaling (HPA). Finally, I created a Helm template to quickly deploy new websites with the required configurations.

Notifi powers personalized interactions and communications between Web3 developers and their users.

I created the whole infrastructure to support Notifi's platform for this project. I used Terraform to script every aspect of the solution, so after deploying it, the application was fully operational with no additional configuration required (except for some external secrets).

Using Kubernetes (EKS) with EBS, External Secrets, Grafana, Prometheus, External DNS, among others, we achieved stability, scalability, and resiliency.

For CI/CD, I used a fully GitOps solution using ArgoCD, Helm charts, and Github Actions pipelines.
