Fintech Platform Suite
Fintech Software Company · 2026 — PresentA fintech product suite — CRM, dealer portal, sub-dealer onboarding, and public website — where dealers are registered and approved, wallets are funded, and bills are paid.
01 About
I'm a Computer Engineering graduate of Batangas State University who went into quality assurance and stayed — because the interesting problems live in the gap between "it works on my machine" and "it works for the person paying for it."
Two products have shaped how I test. Today I cover a fintech suite — a CRM, a dealer portal, a sub-dealer onboarding flow, and the public site — across development and staging, where a wrong balance or a permission that leaks is somebody's money. Before that I led full-cycle QA on a cloud platform professional kitchens use to cost dishes, plan menus, and declare allergens on a printed label — and built its Playwright automation framework from scratch. One taught me transactions, roles, and state. The other taught me calculations and compliance, where the output is something a person with an allergy actually trusts.
The work itself is unglamorous and I like it that way — author the Gherkin cases, automate them in headless Playwright, capture the evidence, then walk each defect from filing through retest to closure. Roughly 15,000 test cases and 3,000 closed tickets later, the habit that stuck is refusing to write a verdict I can't trace back to a real execution.
Lately I've been building the tooling instead of just using it: an AI-assisted QA workspace where a dozen agents draft requirements from a user story, generate and score test cases against a quality gate, execute them in real browsers, produce the report, and sync the results back into the test-management platform over its API. It took the copy-paste out of my week and handed the time back to actual testing.
I'm at my best on products where being wrong is expensive.

Mid Software QA Specialist Fintech Software Company
Quality across a fintech product suite — CRM, dealer portal, sub-dealer onboarding, and the public website — on development and staging.
- Author Gherkin test cases, automate them with headless Playwright, and capture screenshot evidence for every execution.
- Drive the full defect lifecycle from filing through retest to closure, entirely over the tracker's REST API rather than its UI.
- Built the AI-assisted QA workspace the team runs day to day — a dozen agents covering requirements, test-case generation, execution, reporting, and result sync.

Software Quality Assurance Specialist Food Technology Software Company
Led full-cycle QA for a cloud-based food management and inventory web system, from manual testing ownership to building the team's automation infrastructure from the ground up.
- Architected a Playwright + TypeScript automation framework from scratch using POM and OOP principles, automating regression and E2E test cases and reducing manual testing time.
- Executed functional, UI, API, regression, smoke, and exploratory testing across multiple modules using Postman and structured black-box techniques, maintaining stability through continuous requirement changes.
- Managed high-volume defect tracking across thousands of logged issues in Backlog by Nulab — each documented with full replication steps, visual evidence, and root cause analysis to drive permanent fixes and eliminate recurring issues at the source.
- Tested AI-integrated features for output accuracy, consistency, and response quality across varied data inputs.
- Proposed UX and workflow improvements based on testing insights, reducing support requests, and mentored QA interns in best practices.

— Selected work
AI-Assisted QA Workspace
A suite of twelve automation agents covering the whole QA cycle — draft requirements from a user story, generate Gherkin cases, review and score them against a quality gate, execute, report, and sync everything back to the test management platform.
Headless Regression Suite
Playwright runners that execute a test-case workbook end to end, emit live per-case progress, rerun failures up to three times to weed out flakiness, and produce a PDF report with charts, evidence screenshots, and a cause-and-solution block for every failure.
Defect Lifecycle over REST
Bug filing, collection, retesting, and verdict write-back handled entirely through the tracker's REST API instead of the UI — file a defect, pull the Ready-for-QA queue, re-execute it in a browser, and post the result with a comment and round history.
Email Verification Harness
API-driven inbox checking for every email-gated journey — invitations, verification links, OTPs, password resets. No browser, no manual mailbox refresh, and no flaky waits on a message that already arrived.
