Hi, I'm Karina.
Where development meets quality.
More than five years combining web development and quality assurance. I turn requirements into solid products, taking care of every stage: architecture, code, tests and release.
Where I can help.
Six focus areas that I bring together naturally to deliver a complete and reliable product.
Test automation
End-to-end automated suites with Cypress and Playwright, API testing with Postman and parallel execution. Testing strategy designed with ISTQB CTFL 4.0 backing the process.
Backend development
Backend features in PHP and Laravel with Clean Code and the Repository Pattern. Hands-on experience with real-time messaging, payment integrations and analytics, backed by MySQL and MariaDB.
Frontend development
Interfaces in JavaScript and TypeScript, with HTML, CSS and SASS. Clean user experiences supported by code that stays maintainable over time.
Performance testing
Load and stress testing with JMeter to understand how the system responds under real traffic. Clear documentation of findings so the team can act on time.
DevOps & tooling
Docker for consistent environments, Git for version control, and Azure DevOps and Jira for tracking. Pipelines where quality is part of the daily flow, not an afterthought.
Scraping & data
Scraping scripts with Selenium (Python) and Playwright, database validations in MySQL and MariaDB, and geolocation-aware flows when the use case requires it.
My professional journey.
Experience across retail, digital platforms and services, always with one foot in development and the other in quality.
Quality Assurance Senior
I lead the quality strategy for critical features: automated tests, functional and technical validations, metrics and documentation that give the team confidence to deploy. Early risk detection helps us act on time.
Web Developer & QA Automation Engineer
Four and a half years on both sides of the product. Development with PHP, JavaScript, jQuery, MySQL and Docker; QA with Cypress for automated testing (E2E, API, parallelism), Selenium and Playwright for scraping, and JMeter for performance, all within Scrum cycles tracked in Jira.
Backend Developer
Platform migration to Laravel 11 with Clean Code and the Repository Pattern to keep the architecture modular. Development of new backend features, MariaDB management, and integration of real-time messaging, Google Analytics and the payment system.
My technical stack.
Languages, frameworks and platforms I use to design, build, test and deploy.
Who's behind the code.
My career has moved between two complementary worlds: writing code that solves real problems, and validating that it does so reliably. That dual perspective shapes how I approach every project.
I value clean code, well-structured architectures and tests that give the team real confidence. I'm in the final stretch of my Software Engineering degree at UNAPEC, hold the ISTQB CTFL 4.0 certification and continue training in cybersecurity. Ongoing learning is part of how I work.
Education and certifications.
My formal background in software engineering, plus the certifications I keep updating as I grow.
