QA Engineering · Release Management · AI QA
For 14+ years I've helped teams ship their systems to production with confidence — core banking, payments, account opening — building solid QA processes alongside teams at Citi, HSBC, BBVA, Banorte, AXA, and UL Solutions.
Today I take on freelance, contract, and remote work.
Contract or full-time
Remote (Querétaro, MX — CST)
Consumer banking mobile app, then the account opening platform and its automated validation and approval workflows. Seven years on the same client, moving from manual tester to running the release.
Core banking on AS/400 (IBM i). ATM transaction flows, service integration and 5250 interfaces — the layer most testers never touch and every bank still runs on.

At Citi I used AI to generate edge cases on top of 500+ test cases. At UL Solutions I brought in AI-assisted test design, defect clustering and Applitools Visual AI for regression across sites. Sentry AI and TestRail AI are part of my production work.
Chatbots and agents fail differently: a wrong answer can sound completely right. I test them with evals — expected behaviors, edge cases and adversarial prompts — and check for hallucinations, regressions between prompt or model versions, and whether the system stays within its limits.
EnseñAI turns any topic into material for 8 learning styles. Its prompts were designed and tested to reduce hallucinations and keep educational accuracy. [COMPLETAR: how you tested them — how many topics or cases, what you checked, what you changed]
Internal tool I built for my own QA audits. A local Node/Express dashboard with 7 QA agents: test generation (UI and API), accessibility and UX/UI review, structured bug reports and the final Word audit report.
Quality The accessibility scan runs real axe-core on the live page; Claude only summarizes the findings and is told never to invent violations.
An AI event-planning product I designed, built, tested and shipped myself. It generates a timeline, a budget and a digital invitation with RSVP, guided by an in-app planner assistant. Live, with real users and Stripe payments.
Quality Run like a client release: milestone branches, deploy previews, a findings log per version and a beta program with real testers.

Where quality is actually breaking down, what to test and what to stop testing, and a 90-day plan your team can run without me.
Putting AI where it earns its keep: test design, defect clustering, log analysis, visual regression. With the guardrails that keep it from generating confident nonsense.
API and end-to-end testing, UAT coordination with business stakeholders, traceability and evidence packs that survive an audit.
A real QA audit — functional testing, API validation and an automated WCAG 2.1 AA accessibility scan. 23 findings ranked by severity, with evidence, probable root cause and a recommended fix for each. This is my own product, audited with the same method and format I deliver to clients.
QA audits — including for apps built with AI — now live at TestingVibe, with their own packages and pricing.
Manual and exploratory, API testing with Postman and SOAP UI, UAT, regression, smoke, end-to-end, accessibility. Python for smoke automation, Selenium, SQL Server, DB2, AS/400.
Azure DevOps, Jira, Confluence. Release planning, cutover execution, risk and change management, incident tracking, deployment coordination across teams and time zones.
Claude, GitHub Copilot, Applitools Visual AI, Postman AI, Sentry AI, TestRail AI, Testsigma, LambdaTest — used in production work, not in a course.
