Experience

Link Social Media Application

I designed and implemented the entire cloud architecture on AWS using Terraform and deployed microservices on EKS across three environments using Helm charts and later GitOps principles. I built and automated GitLab CI/CD pipelines for seamless deployments and later moved to Argo CD. I also automated daily SRE reports for system health monitoring and used Prometheus for metrics collection, Loki and Promtail for logging, and
Grafana for visualization. I optimized AWS costs by utilizing ARM instances, Reserved Instances, and Spot Instances. I implemented WAF and Wazuh for application security and HashiCorp Vault for centralized secrets management.

PsychPlus Healthcare Platform

I provisioned and deployed infrastructure on Azure using Terraform and deployed microservices on Azure Kubernetes Service (AKS) and set up CI/CD using GitHub Actions. I integrated New Relic, Prometheus, and Grafana for APM and monitoring. I designed a scalable and secure cloud architecture using Azure services like Entra ID, Azure Storage, Azure Monitor, Azure Security Center, and HyperScale SQL databases.

Telnyx On-premise Infrastructure Management

I managed on-premise infrastructure and set up Proxmox to create and manage virtual machines. I also deployed and maintained Kubernetes clusters on virtualized environments, configured network-related settings, and optimized traffic routing. I implemented NetBox for IP address management and Ansible for automation.

Rebag eCommerce Platform

I migrated infrastructure from Heroku to AWS, provisioning Network, Load Balancer, RDS, and Redis for their apps using CloudFormation. I dockerized applications and deployed them to AWS Fargate using CloudFormation. I also set up GitLab pipelines for continuous deployments.
