As a DevOps Specialist, I design and implement scalable Kubernetes environments to enhance operational efficiency and system reliability. My expertise includes setting up and maintaining clusters, optimizing for performance, security, and high availability.I utilize ArgoCD for continuous delivery, integrating with GitHub Actions and Jenkins to streamline CI/CD pipelines. This automation improves deployment speed and reliability while minimizing manual intervention.I develop and automate workflows using Bash and Python scripting, which enhances task automation and system reliability. For infrastructure management, I employ Terraform with custom and community modules, ensuring consistent and scalable resource provisioning.Architecting microservices with Kubernetes and AWS Lambda is central to our cloud-native strategy, supporting modular, scalable applications and rapid deployment cycles. I manage AWS API Gateway for efficient API handling and secure interactions.Cost management is a priority, with a focus on infrastructure-related cost reduction to optimize resource use and budget. I monitor usage patterns and implement measures to reduce expenses while maintaining performance.For visibility and monitoring, I use CloudWatch for log management and Datadog for tracing and performance analysis. These tools provide insights into system performance and help proactively address issues.Driven by a commitment to excellence and continuous improvement, I stay updated with industry trends and emerging technologies, applying them to enhance our infrastructure. Through collaboration and innovation, I ensure our systems are resilient, cost-effective, and aligned with business goals.

Performed maintenance and contributed to improvement of legacy infrastructure and monolithic application stack. Designed and implemented a microservice architecture to replace legacy systems.Solution Arquitechture:Design and implementation of a new microservice-oriented infrastructure solution consisting of:- Kubernetes Cluster- Pod autoscaling- Nginx Ingress Controller- Jaeger for observability- Helm chart deployments- CI/CD- DNS naming convention- Networking- Packer for EKS node images- Prometheus and Grafana for monitoring, visualization and alerts- ELK stack for logging- Application lifecycle pipeline design with Jenkins- Git branching model analysis- Sonarqube for static code analysisEverything in the new infrastructure was developed and deployed as Infrastructure as Code using Terraform, with custom in-house written modules. Which enabled us to move away from the previous Ansible solution.Migration to new platform:Designed a migration plan to move from the legacy monolithic application towards Kubernetes microservices. Implemented the plan and successfully migrated platforms without any unplanned downtime.Platform improvement and development:Iteration over existing infra to improve performance, flexibility, and developer experience. Including:- Replacing Nginx with Traefik for ingress controller- Deployed Istio for Service Mesh features- Changed Git branching model towards Single Artifact Promotion- Switched from Jenkins to ArgoCD- Design and implementation of AWS multi-account arquitechture
