I am a dedicated Software Quality Assurance Engineer with over 4 years of professional experience in manual and automated testing across web and mobile applications. My career includes working with companies like Syntax Solution Limited, Ejogajog Limited, and MASTER WiZER, where I contributed to projects involving transportation management systems, ride-sharing platforms, e-commerce, and automation services. I specialize in creating detailed test plans, writing reusable test cases, and executing functional, regression, and API testing.

Playwright automation frameworks and Maestro Studio mobile testing, built for SaaS and Fintech teams that cannot afford broken releases. 5+ years delivering end-to-end QA across web, Android, and iOS — from test strategy to CI/CD pipeline integration. I have led QA for enterprise clients at Accenture and Cognizant across Telecom (eSIM provisioning), Life Insurance (Guardian Life B2C platform), and Cloud SaaS — owning the full quality lifecycle from sprint planning through release sign-off. My Playwright and Selenium test automation frameworks have gone into production for teams of 50+ engineers, and my Maestro Studio flows have replaced hours of manual testing with fully automated CI-triggered runs. What I bring that most QA engineers do not: I build frameworks your team can maintain after I leave, write test strategies tied to business risk rather than feature checklists, and communicate at a senior level with developers, PMs, and non-technical stakeholders. For SaaS and Fintech clients, I understand what a broken payment flow, failed onboarding, or checkout regression costs in production — and I design coverage around those risks from day one. 🎯 Core Specializations Playwright Automation (Web) Playwright framework design and development (JavaScript/TypeScript) Cross-browser test automation: Chromium, Firefox, WebKit Page Object Model, fixtures, and scalable test architecture CI/CD integration: GitHub Actions, Jenkins, GitLab Parallel execution and flaky test elimination Maestro Studio - Mobile QA Automation Mobile test automation for Android and iOS using Maestro Studio Flow-based UI testing, gesture simulation, and assertion design Maestro Cloud integration for continuous mobile testing Deep-link, push notification, and offline scenario testing Mobile and API Testing Appium-based cross-platform mobile test automation REST API testing with Postman: schema validation, auth flows, contract testing Manual testing: functional, UAT, smoke, sanity, and regression testing App Store and Play Store pre-release validation Senior QA Leadership and SDET End-to-end QA ownership: strategy, planning, execution, release sign-off QA process setup for startups and scaling engineering teams Agile/Scrum QA: sprint planning, defect triage, release readiness Mentoring junior QA engineers and stakeholder reporting 🛠 Tech Stack Web Automation: Playwright, Selenium, TestNG, Cucumber Mobile Automation: Maestro Studio, Appium Languages: JavaScript, TypeScript, Java API Testing: Postman, REST Performance: JMeter CI/CD: GitHub Actions, Jenkins, GitLab CI Bug Tracking: JIRA, Confluence, qTest, ALM Octane 🏆 Key Achievements Built Playwright and Selenium test automation frameworks from scratch for SaaS and Cloud platforms Implemented Maestro Studio mobile automation for Android and iOS production apps Reduced mobile regression testing from manual hours to automated CI-triggered runs Led QA across 5+ enterprise projects: SaaS, Insurance, Telecom, Fintech Set up QA processes from zero for early-stage startups before first release 100% Job Success on Upwork across SaaS, Insurance, Telecom, and Cloud domains 📋 Industries: SaaS, Fintech, Insurance Tech, Telecom (eSIM), Cloud Applications, E-commerce 📩 Available now for Playwright automation, Maestro Studio mobile testing, manual testing, API testing, SDET contracts, or full QA lifecycle ownership — test strategy through release sign-off.

I sit at the intersection of three things Upwork clients need most right now: building AI systems, testing that they actually work, and managing the delivery so nothing falls through the cracks. Most freelancers do one of these. I do all three, which means you get one person who can take a workflow from idea to production without coordinating between a developer, a QA person, and a project manager. I am a Technical Project Manager currently delivering enterprise projects for STC, one of the largest telecoms companies in the Middle East, while running a parallel freelance practice building AI automation systems for clients across the US, UK, and MENA. I manage complexity for a living and I operate with full ownership, not as someone waiting to be told what to do next. What I build and deliver: On the AI automation side I design and build production-grade workflows using n8n, Make, and Zapier connected to Claude, GPT, and other LLMs. These are not demo automations. They run at real volume, have error handling and retry logic, and keep working without someone watching them. I have built systems processing 1,000 cases per week and AI agents handling multi-platform customer operations around the clock. On the QA side I handle manual testing, regression, exploratory testing, API testing with Postman, and test automation with Playwright. I write clear bug reports, catch edge cases before they reach production, and validate end-to-end workflows so releases do not break things. On the project management side I run sprint planning, backlog management, cross-functional coordination, and stakeholder communication. I use Jira, ClickUp, and Notion. I give clear updates without being asked and flag blockers the same day they appear. Where I work best: - AI workflow automation using n8n, Make, Zapier - Claude and GPT integrations with structured outputs - API integrations, webhooks, and multi-platform pipelines - CRM and business process automation - Technical project and product management - SaaS QA and end-to-end product testing - API testing and backend validation - FinTech QA and system testing - Agile delivery, sprint management, and backlog ownership If you send me an invitation I will send you a personalised Loom on how I would approach your specific project.
