Pritam Roy: From Network Engineer to AWS DevOps & Cloud Engineer

#aws #devops #automation #linux

When I started my career in IT, I didn’t begin in the cloud or with automation tools. I began by understanding how systems behave when they fail.

I’m Pritam Roy, and over the past 9+ years in IT, my journey has taken me from working in network operations to designing and managing large-scale AWS cloud infrastructure and DevOps pipelines for production environments.

Where It Started

I began my career in a Network Operations Center, monitoring enterprise MPLS and ILL networks. Working in a 24×7 operations environment taught me something that no certification can teach:

Reliability matters more than theory.

Seeing outages, latency spikes, and configuration issues in real time helped me understand how critical stability, monitoring, and structured processes are in infrastructure engineering.

Transitioning to Cloud and DevOps

During the pandemic, I used that period to deeply invest in learning AWS, Linux systems, infrastructure automation, and deployment pipelines.

Instead of focusing only on courses, I practiced by building real environments:

Automated deployments on AWS
CI/CD pipelines for application delivery
Secure networking setups
Infrastructure provisioning using Terraform

That shift changed the trajectory of my career.

Working in Production Cloud Environments

Today, I work as a Senior AWS Cloud and DevOps Engineer managing real production infrastructure.

My work includes:

Managing hundreds of EC2 instances across environments
Designing secure AWS VPC architectures
Building CI/CD pipelines for Java, Node.js, React, Angular, and mobile apps
Running containerized workloads with Docker and Kubernetes
Implementing monitoring with Prometheus, Grafana, and CloudWatch
Strengthening infrastructure security with IAM, GuardDuty, and WAF

Working in fintech environments especially taught me how critical reliability, observability, and automation are.

Infrastructure in such environments cannot afford downtime or weak security models.

My Approach to DevOps

For me, DevOps isn’t about tools. It’s about how systems are designed.

I focus on:

Automation — anything repeatable should be automated
Security — infrastructure must be secure by design
Scalability — systems should grow without breaking
Observability — if you can’t see it, you can’t fix it

If a system requires constant manual intervention, it isn’t engineered yet.
