Cloud infrastructure & delivery pipelines

Managed AWS infrastructure, containerised applications onto Docker and Kubernetes, and set up Jenkins and GitLab pipelines that sped up delivery.

Deployment & DevOps

40%

Faster deployments after containerisation

40%

Better system efficiency from monitoring

40–50%

Faster software delivery with CI/CD

01Context

My first engineering role: a Cloud & DevOps internship at EPAM Systems.

02Challenge

Applications needed reliable, secure AWS infrastructure, faster deployments and pipelines that let teams ship without manual steps.

03Approach

  1. 01

    Run the AWS estate

    Managed VPC, EC2, S3, Lambda and IAM roles for day-to-day cloud operations.

  2. 02

    Tune the network

    Optimised ALB configurations, subnets and security groups for efficiency and security.

  3. 03

    Containerise

    Integrated applications into Docker and Kubernetes environments, with troubleshooting and documentation to match.

  4. 04

    Measure

    Led performance monitoring initiatives to find bottlenecks.

  5. 05

    Pipeline everything

    Set up CI/CD pipelines with Jenkins and GitLab.
