I build reliable quality systems for modern products through automation, API validation, performance testing, and CI/CD quality gates.

With 4+ years of experience in software quality, I’ve worked on web and mobile applications across domains such as E-Commerce, Retail, Logistics, Healthcare, Rental, AI, Hospitality, and Travel.

I’m a QA Engineer who enjoys transforming testing into a scalable engineering practice, not just a release checklist.

My work focuses on:

• building maintainable E2E and API automation frameworks
• validating system reliability through performance testing and observability
• improving release confidence with CI/CD-integrated quality gates
• collaborating closely with product, engineering, and operations teams

I’m particularly interested in the intersection of
quality engineering, automation architecture, system reliability, and developer workflow.

Right now, I’m building and refining projects around:

• Playwright + BDD automation
• API and microservice quality engineering
• k6 performance testing
• synthetic monitoring
• GitHub Actions based QA pipelines
• observability-driven validation with Prometheus and Grafana

A microservice quality engineering blueprint covering:

• unit, contract, API, E2E, and performance testing
• Playwright, Pact, Supertest, and k6
• Prometheus and Grafana observability
• GitHub Actions quality gates

A production-style automation framework built with:

• Playwright
• Cucumber.js
• TypeScript
• Page Object Model
• Docker and GitHub Actions

A performance engineering project focused on:

• automated load testing with k6
• SLA validation
• Prometheus/Grafana correlation
• reporting and notification workflow

A synthetic monitoring framework that automates:

• API health checks
• end-to-end user journey validation
• scheduled execution through GitHub Actions

An API automation framework designed for:

• regression testing
• negative testing
• environment-based execution
• CI-ready reporting
