Building Reliable Cloud Infrastructure with AWS, Kubernetes & Automation

I'm a DevOps Engineer specializing in cloud infrastructure, Kubernetes, CI/CD, and Infrastructure as Code. I focus on building scalable and reliable environments, automating delivery workflows, and improving the observability and operational reliability of production systems.

My experience includes running production workloads on Amazon EKS, implementing CI/CD with Jenkins, GitHub Actions, and Argo CD, and managing infrastructure through Terraform. I also work with AWS and Azure services, containerized workloads, monitoring and observability, and Python-based automation to streamline day-to-day operations.

Cloud infrastructure & Kubernetes projects

Platforms I've built and kept running, not just spun up once.

Cloud-native platform

101Gen.ai

Built on AWS, Kubernetes, and EKS — transformed a monolith into scalable microservices, deploying Keycloak, Weaviate, MongoDB, Redis, PostgreSQL, and application workloads across the platform. Centralized error monitoring and operational automation with Python.

Multi-AZ EKS platform across 3 availability zones with ALB ingress for app and auth traffic
~40% faster release cycles after standardizing Docker → ECR → Kubernetes deploy paths
Centralized metrics/logs cut production triage time with Prometheus, Grafana, and Python automation

DevOps lifecycle

Greenlight — CareerConnect

End-to-end DevOps across containerization, CI/CD, Kubernetes, and observability. Ran Amazon EKS workloads with dedicated node groups, ingress, secrets, storage, autoscaling, and service-to-service connectivity.

Full CI/CD on Jenkins covering build, scan, deploy, and rollout validation on EKS
HPA + dedicated node groups improved capacity handling under peak interview traffic
Grafana + Loki stack gave one pane for metrics and logs across services

Identity & access

AWS VPN + Google Workspace SAML

End-to-end AWS VPN integration with Google Workspace SAML authentication, enabling secure enterprise access without adding friction for engineers.

SSO via Google Workspace SAML — no separate VPN passwords for engineers
Least-privilege IAM + Client VPN reduced shared-credential risk for private VPC access

FinTech / E-invoicing

Taxlabs

Automated backend deployment pipelines with Jenkins; shipped frontend releases through static hosting and CDN. Added Azure Monitor and Grafana monitoring plus log backup and alerting.

Jenkins pipelines cut manual backend release steps and made deploys repeatable
Frontend delivery via static hosting + CDN improved global asset load times
Azure Monitor + Grafana alerting caught failures before customers reported them
