A fully remote QA role where solid manual testing, API checks, and SQL data validation make a real difference. I want to own quality on a product, work closely with developers and product teams, and keep growing into test automation. Fintech, payments, data products, and e-commerce interest me most. Open to contractor or full-time roles and available to start right away.

Senior manual QA, 9 years testing web apps end to end: Postman APIs, SQL backend checks, fintech payment flows. Remote from Colombia.
What I'm looking for
I’m a QA engineer with 9 years of experience testing complex web applications, and I’m happiest when I’m digging into why something that looks fine is actually wrong.
Most recently I spent almost four years at Exadel as the sole QA on several feature tracks. I planned the testing, ran it, managed the defects, and made the call on whether each release was ready, keeping the share of defects that reached production under 2%. Day to day, that meant testing REST APIs in Postman and then writing SQL to confirm the database told the same story as the screen.
Before that, at Globant, I led a team of three QA engineers through three releases with zero critical defects reaching production, validated data releases in Azure Synapse, and tested a mobile app connected to drive-thru sensors. My first QA role was four years at Open International, testing billing cycles, invoices, and payment flows on a large enterprise platform. That’s where I learned how much care anything touching money deserves.
I use AI tools like Claude Code and ChatGPT every day to design better tests faster, and I’m currently building my automation skills with Playwright.
I’m a native English and Spanish speaker, based in Cali, Colombia, and I’m looking for a fully remote QA role where solid manual testing, API and data validation, and clear communication matter. Fintech, data products, and e-commerce interest me most.
Experience
Work history, roles, and key accomplishments
Sole QA owner across multiple feature tracks on an enterprise web product: test plans, execution, and release-readiness calls. Tested end to end through UI, REST APIs (Postman), and SQL Server data, kept production defect escapes under 2%, and used Claude Code, ChatGPT, and Copilot daily to design sharper tests.
Led three QA engineers through functional, regression, exploratory, and end-to-end testing across three releases with zero critical defect escapes. Validated data releases in Azure Synapse, tested a sensor-connected mobile app on Android, wrote Gherkin/Cucumber scenarios that sped up defect triage by 40%, and onboarded two QAs in two weeks.
