QA Engineer for SaaS Platform - API Testing & Automation

@Microlent

Hello, Building a SaaS marketplace for VCs means quality is your reputation. I don’t view QA as just chasing tickets; it’s about establishing strict API contracts and a solid test pyramid so your team can ship without fear. Coming from a strong backend background, I specialize in white-box testing. I build robust automation suites using Pytest and Playwright, wired directly into CI/CD pipelines via Docker. I also leverage AI tools to accelerate test generation. You can review my QA report, where I managed testing for 44+ projects with zero critical production defects: * QA Report: https://www.freelancer.com/portfolio-items/11354470-software-qa-testing-report How I’ll own your strategy: * API & Performance: Deep REST validation and k6/JMeter load testing to find your breaking points. * Pipeline Integration: Automated, containerized gatekeepers for your deployments. Action Plan: I’ll start by auditing your APIs to establish baseline contracts, then set up the foundational Pytest/Playwright framework in your CI/CD. Let's open the chat—I'd love to quickly discuss your current infrastructure. Best, Jenifer

Hello, I can take ownership of your QA strategy end-to-end and build a scalable testing foundation aligned with how your SaaS will grow. How I’ll approach this: 1. API Testing (core focus) • Treat APIs as contracts (happy + negative paths, schema, auth, edge cases) • Build robust suites using Python + Pytest and validate flows with Postman • Cover error handling, rate limits, and data integrity 2. Test Automation Framework • E2E + UI automation using Playwright (TypeScript/Python) • Follow test pyramid (API-heavy, minimal UI flakiness) • Stable architecture (POM, fixtures, reusable utilities) 3. Performance Testing • Load/stress scenarios using k6 or Apache JMeter • Identify bottlenecks, breaking points, and scaling limits 4. CI/CD Integration • Pipeline setup in GitHub Actions or GitLab CI • Parallel execution, reporting, and failure insights 5. Test Strategy & QA Ownership • Define coverage from requirements • Build test management structure (cases, metrics, traceability) • Introduce AI-assisted testing (test generation, anomaly detection) where useful Deliverables: • Automation framework (API + UI) • Performance test suite + reports • CI/CD-integrated pipelines • Coverage analysis + QA roadmap Why I fit: Strong background in automation, API validation, and building QA processes from scratch, with a focus on reliability and maintainability—not just test volume. Ready to start and shape your QA practice properly from day one.

@dvcontact

Hi, Likely root cause: gaps in contract-level API validation and missing automated performance gates—your marketplace’s reputation risk comes from silent failures under edge loads and CI flakiness. I see you need API behavior testing, Playwright/Pytest-style automation, k6/JMeter performance testing, GitLab/GitHub CI integration, and Dockerized test environments. First debug angle: build schema-driven API contract tests + idempotent test harness to stop duplicate records and flaky CI runs. Planned actions: - Implement Pytest-based contract tests + Playwright for UI flows; integrate with GitLab CI - Add k6 load scenarios, result thresholds, and anomaly alerts I’ll prioritize reliability and low-risk rollout. Ready to start and sync with your backend lead. — Smith
