09.2021 - 02.2026
- Developed and maintained automated API and microservice tests using Karate to validate key customer and service journeys across a large, distributed telecoms platform.
- Built a reusable Dynatrace-based assertion framework that called subsystem-specific checks from Karate, strengthening observability and making issues easier to spot earlier in the testing lifecycle.
- Integrated automated tests into CI/CD pipelines, ensuring regression checks ran on every change and providing prompt feedback to developers.
- Collaborated with developers and operations teams to investigate failures using Dynatrace dashboards and logs, helping to speed up root-cause analysis and stabilise releases.
- Shared Dynatrace query patterns, assertion ideas and pipeline best practices with teammates (e.g. better use of test data and variables), encouraging more automation-first, DevOps-aligned ways of working across the team.
- Designed, built and maintained automated API and microservice tests using Karate, feeding results into CI/CD pipelines to give swift feedback on each deployment.
- Developed a Python Flask tool to automate log analysis for test runs, integrating with observability tooling (Dynatrace, centralised logs) to automatically flag anomalies and surface edge-case failures.
- Worked closely with developers and platform teams to embed DevOps best practices in testing, monitoring, and release workflows, improving system reliability and deployment confidence.
- Created reusable, data-driven test frameworks and assertion patterns that reduced manual effort and made failures easier to diagnose, supporting smoother continuous delivery.
- Contributed to team ways of working by promoting automation-first approaches, documenting solutions, and mentoring junior engineers on DevOps-aligned tooling and practices.
- Complemented day-to-day work with self-directed DevOps projects (e.g. Terraform-provisioned ECS/Fargate app on AWS with CI/CD and observability), strengthening practical skills in cloud infrastructure and container platforms.

PROJECTS
Containerised Threat Modelling App on AWS ECS Fargate, Designed and implemented a containerised web application running on AWS ECS Fargate behind an Application Load Balancer (ALB), with images stored in Amazon ECR., Used Terraform to define and provision core infrastructure components, including VPC, subnets, security groups, ECS services, ALB and ECR, enabling repeatable, version-controlled infrastructure changes., Set up GitHub Actions CI/CD pipelines with OIDC authentication to AWS, automating Docker image builds, security scanning and pushes to ECR, followed by deployments to ECS., Followed infrastructure-as-code and DevOps best practices, including environment-specific configuration, state management for Terraform, and pre-commit checks for Terraform security and formatting., Implemented logging and monitoring with a custom dashboard for metrics and logs for the ECS Fargate service using CloudWatch improving visibility into application behaviour and deployment issues.
