Alijah Luis Mancera.

I started out building things to learn how they worked. Now I build them because I still haven't found anything I'd rather do. Mostly web, whatever stack the project calls for.

My experience revolves around test automation. I've helped companies grow and streamline their QA processes.

Lately, I've been diving deeper into the world of AI, focusing on integrating such tools and techniques into modern applications. On the side, I like to work on projects that involve building modern web applications.

I've worked across e-commerce, fintech, real estate, banking, and e-learning. Different stacks, same instinct to keep things from breaking.

Led automation design & review processes across web and mobile using Cypress and Robot Framework.

Built scalable test automation frameworks (Selenium, Playwright, Appium) cutting manual testing by 40%. Mentored QA engineers transitioning to automation.

One of the first Test Engineers in the chapter. Reduced project delivery turnaround by 50% through CI/CD pipelines and automated scripts.

One of the key persons that started the automation process. Set up a Selenium-based framework and CI/CD pipeline that cut testing turnaround time significantly.

Designed and implemented a Selenium-based automation framework from scratch, adopted team-wide.

Extended the Selenium framework for cross-team use. Solo performance engineer using New Relic and Grafana.
