QA & Performance
We implement complete testing strategies and performance optimization. Automated tests, Core Web Vitals audits, and continuous monitoring to guarantee product quality. We use Playwright for E2E tests, Jest for unit tests, and Lighthouse CI for performance. The goal is that every deploy has confidence that nothing broke and load times stay within Google's standards.
Un bug detectado en produccion cuesta hasta 100 veces mas que si se detecta en la fase de diseno o desarrollo (IBM Systems Sciences Institute)
Google reporta que cada segundo adicional de tiempo de carga reduce las conversiones aproximadamente un 7% en e-commerce
La inversion en QA temprana y performance tiene retornos muy claros: menos bugs, mejor experiencia, mas conversion. Es de los servicios con mejor ROI demostrable.
Deliverables
Process
Diagnosis
We identify product areas without test coverage and performance bottlenecks.
Strategy
We define what to test, with which tools, and performance thresholds.
Implementation
We write tests, configure Lighthouse CI and Sentry.
Automation
We integrate everything into the CI pipeline to run on every PR.
FAQ
What are Core Web Vitals?
They're Google's metrics that measure user experience: LCP (Largest Contentful Paint — load speed), INP (Interaction to Next Paint — responsiveness), and CLS (Cumulative Layout Shift — visual stability). They directly affect SEO.
Can you do QA on a product you didn't develop?
Yes. We do quality and performance audits on any web product, regardless of who built it. We deliver a report with prioritized findings and recommendations.
What test coverage do you recommend?
We don't chase arbitrary percentages. We prioritize tests on critical business paths (checkout, auth, payments) and code that changes frequently. 70-80% coverage on the core is usually a good target.
Do you use Playwright or Cypress for E2E?
We prefer Playwright for its native multi-browser support, better performance, and more modern API. But if the project already uses Cypress, we work with what's there without forcing an unnecessary migration.
