AWS / Cloud Infrastructure: Independently designed, built, and maintained Kubernetes-based
infrastructure in AWS for production and development environments, with hands-on use of EKS,
EC2, ECR, S3, Aurora PostgreSQL, DMS, and AWS Load Balancers (ALB/NLB).
Terraform / Infrastructure as Code: Provisioned cloud infrastructure from scratch using a modular
Terraform approach, creating reusable and maintainable building blocks for cluster and platform
components.
Kubernetes / Container Platform: Operated a containerized, Kubernetes-based service architecture
in AWS, supporting application workloads, asynchronous services, and platform-level components
in production-like environments.
Scaling / Reliability / High Availability: Implemented workload-driven autoscaling across multiple
layers, including HPA for application pods, KEDA for queue-based workers, ingress controller
scaling for traffic handling, and Karpenter for dynamic node provisioning and cluster capacity
management.
Messaging / Async Processing: Deployed and maintained Celery services with RabbitMQ inside
the Kubernetes environment to support asynchronous task execution.
CI/CD / Release Automation: Built and maintained GitLab CI pipelines for automated delivery into
Kubernetes, using Helm for application deployment and release standardization.
Odoo / Application Deployment: Automated deployment of Odoo CRM systems with Ansible and
CI/CD, including Nginx configuration, deployment of custom modules, and handling of module
update issues such as HTTP 500 scenarios.
Observability / Monitoring / Logging: Implemented centralized observability with Prometheus,
Grafana, and Loki, including alerting and dashboards for real-time infrastructure and application
monitoring.
Networking / Multi-Cloud Exposure: Worked across AWS, DigitalOcean, and Hetzner environments,
with practical involvement in cloud infrastructure, networking, and service delivery.
LLM / AI Integration: Deployed local LLM models with Ollama, used them in practice, and
participated in integrating an AI/LLM module into a commercial product.

AWS / Kubernetes: Deployed Kubernetes infrastructure in AWS, including the deployment of
multi-tenant Odoo systems into the cluster using Helm charts and CI/CD pipelines.
Terraform / Infrastructure Provisioning: Provisioned Kubernetes cluster infrastructure in AWS
using a modular Terraform approach.
CI/CD / Application Deployment: Implemented automated application deployment using Helm
charts and templates within CI/CD processes. Also automated the build process for a desktop
application, including automatic versioning.
Networking / Security: Configured network infrastructure, including Cloudflare, DNS, firewall
rules, and secure service communication.
