Lucas De MedeirosSoftware Developer & DevOps Engineer

I build software and run infrastructure.

I write code, automate tests, and build deployment pipelines. After a release, I want to know what ran, what failed, and where to look next.

Selected work

Software, delivery systems, and infrastructure, with the engineering decisions behind each build.

An AKS delivery platform that reconciles Git-managed workloads, enforces admission policies, stages releases, and exposes rollout health.

An API for text and image fragments that stored one original and converted supported formats on read.

My own hardware runs Azure DevOps agents for validated releases to Azure Web Apps, with private access through Tailscale.

Team-wide initiative. My migration of legacy test logic contributed to this result.

Analyzed and reimplemented legacy UFT/VBScript test logic in Java and Selenium WebDriver.
Developed reusable Selenium components and maintained automated tests for assigned CPIN workflows in the IBM Cúram framework.
Integrated regression runs into Azure DevOps CI/CD build triggers using Maven, then added Extent Reports to improve defect traceability.
Wrote and executed test cases from service requirements, then manually verified incident fixes and service updates to support stable production releases.
