I’m a QA Engineer (Manual/Functional), Test Lead, and Certified Scrum Master (SAFe & -----------) with a strong background in both software and hardware performance testing. Over the years, I’ve worked with Accenture Inc. and Lexmark R&D, leading Agile teams to deliver enterprise-grade projects with precision and efficiency.

I’m passionate about improving testing processes, enabling smooth Agile delivery, and mentoring cross-functional teams. I thrive in remote and global team environments, ensuring communication and delivery excellence.

Computer Engineer with experience in software development, QA testing, and system validation through academic projects and freelance work. Skilled in manual testing, API testing, and Agile SDLC processes with hands-on experience in Python, JavaScript, SQL, Git, Postman, and Jira. Strong ability in debugging, test case design, and ensuring software quality and system reliability

I'm a Senior QA professional with 15+ years of enterprise testing experience, now focused on quality assurance for AI powered products.

I'm ISTQB CT-GenAI certified and have built portfolio projects using Claude AI for code generation and the OpenAI API for automated test case creation. My work blends traditional QA rigor — risk-based testing, RCA, regression strategy, defect analytics — with the newer discipline of evaluating non-deterministic AI behavior: prompt design for test coverage, model regression checks, response quality scoring, and fallback validation.
Domains I've shipped quality in: SaaS / HR tech, insurance, healthcare copay systems, airline reservations, and IT service platforms. I've owned QA end-to-end as a solo tester, led distributed teams across PH and India, and served as a panel evaluator for QA hiring.
What I bring to an AI-forward team: • Test strategy for both deterministic (SaaS, web, mobile) and non-deterministic (LLM, conversational AI) systems • Prompt engineering applied to regression and exploratory test design • Risk-based prioritization — knowing which failure modes actually matter for the business • Clean defect lifecycle management in Azure DevOps, JIRA, Zephyr Scale, TestMo, TestRail • Foundational automation exposure (Selenium, JUnit, Java) and active upskillingPursuing a Master of Business Analytics at Mapúa University (expected Dec 2027) to deepen my data and analytics fluency.

I am a highly skilled Software QA Engineer with extensive experience in both manual and automated testing, specializing in building robust automation frameworks using Python, Selenium, and Playwright. I also have expertise in designing and executing API tests to ensure seamless integration and functionality. My services include developing and maintaining automation frameworks, writing parameterized and data-driven test scripts, designing and executing comprehensive test cases, and managing defect tracking using tools like Jira. With a strong background in requirement analysis, bug reporting, and test environment setup, I am committed to delivering high-quality results. I have a proven track record of collaborating effectively with development teams to enhance QA processes and ensure project success. Whether you need to refine your existing QA strategy or build a reliable testing process from the ground up, I am here to help deliver flawless results.

A QA professional with two years of experience in the industry, specializing in testing web and mobile applications. Practiced and experienced in identifying bugs, creating detailed test cases, and comfortable with collaborating with developers in a fast paced environment.

Software Developer | Automation, ETL Pipelines, API Integration & Backend Systems

I'm a software developer based in Cebu, currently a Software Developer II at a data outsourcing startup. I build production automation and backend systems, work that ships and stays running, not just demo apps.

What I can do for your business:
- Automate manual workflows eating up your team's hours — data entry, report generation, file processing, recurring exports
- Build custom integrations between your tools (CRMs, Google Workspace, Notion, Airtable, OpenAI/Claude, anything with an API)
- Extract data from sources you can't easily get to like public records, PDFs, scanned documents, complex websites and deliver it clean and structured
- Build internal tools, dashboards, or admin panels tailored to how your team actually works, instead of forcing you into another SaaS
- Take an existing system that's slow, fragile, or held together by duct tape and refactor it into something maintainable
- Migrate, unify, or clean up messy databases without losing data

A few things I've shipped recently:
- Migrated 75,000+ records across fragmented databases into a unified store, supporting a new subscription product
- Built Flask-based pipeline orchestration on VPS handling daily client deliveries with fault recovery
- Lifted automated data feed accuracy by 23% across diverse sources
- Boosted my own output by 40% using AI-assisted dev workflows

Stack: Python, C#, Javascript / Typescript, Flask, ASP.NET, Vue.js, Playwright, PostgreSQL, MSSQL, MongoDB, OpenAI API, Claude API, Google APIs.
