What I'm looking for

I’m interested in helping users work effectively with APIs and digital products.

At GEO Digital, I tested REST APIs and billing and data-import workflows, checking that they behaved as expected.

I used SQL to validate data across systems and investigate inconsistencies. I documented defects with evidence and reproduction steps, then followed up on fixes with developers and retested them.

I also documented payment workflows, including payment slip generation, and scheduled automation processes using CRON. I used Postman, Python, and Selenium in my testing work.

During three seasons with Stevens Pass, Vail Resorts, I worked in a customer-facing environment and communicated daily in English with customers and a multicultural team. I’m interested in helping users work effectively with APIs and digital products.
