QA Engineer with experience testing web and mobile applications across SaaS, education, marketplace, and lifestyle products. My experience includes working in both freelance and company environments, collaborating with development teams, executing regression cycles, validating A/B testing variations, and ensuring product quality across multiple releases. What I can help with: - test case and checklist creation - exploratory, smoke and regression testing - bug reporting with clear reproduction steps - pixel-perfect Figma validation - UI/UX validation and workflow testing - QA localisation - API testing - test automation support In addition to QA, I have 8+ years of remote work experience, strong organizational skills, and the ability to support documentation, workflow coordination, and product-related tasks when needed. Currently pursuing a degree in Software and Information Technologies, with exposure to multiple programming languages and development tools. If you're looking for a reliable QA who communicates clearly, thinks critically, and pays attention to details - I'd be glad to work with you.

If you need someone who shows up, figures it out, and doesn't disappear when things get complicated — that's me. I'm a Top Rated Plus freelancer with 100% Job Success, $100K+ earned across 41 contracts, and 7,600+ hours on Upwork. Clients keep me long-term because I don't just complete tasks — I notice what's broken, flag it, and fix it before it becomes your problem. What I do: I specialize in operations coordination and virtual assistance for property management, CRM platforms, and remote teams. I keep workflows moving, vendors accountable, and nothing falls through the cracks. Where I've done it: Property management operations — dispatching contractors, tracking work orders end-to-end, coordinating with tenants and vendors, escalating urgent repairs, and reporting daily to ownership. I've handled everything from scheduling HVAC emergencies to chasing down unresponsive tenants across multi-channel outreach. CRM administration — at Pipeliner CRM I managed onboarding workflows, built automations, supported users, and handled marketing tasks. Seven years, still trusted by the same client. Process documentation & SOPs — I document what I do so it's repeatable, scalable, and doesn't live only in my head. How I work: I'm remote, independent, and reliable. I learn new software fast — my background in QA testing means I don't just use tools, I understand how they work and where they break. I flag problems early, communicate proactively, and I don't wait to be told what to do next. One client said it better than I can: "She delivered on actionable items within expectations and beyond, pointed out holes in our process that could be improved, and was always there when I needed her. HIRE HER. It would be your loss if you do not." If you're looking for someone to own a piece of your operations long-term — let's talk.
