I am a Computer Science Engineer with a postgraduate diploma in Network Security and 5+ years of hands-on experience delivering quality assurance across real-world systems including web apps, SaaS platforms, hardware-integrated products, and network-centric environments. I have tested products end-to-end before production releases, identifying functional, usability, data-flow, and edge-case issues early to reduce release risk and improve system stability and user experience. What I have Done & Delivered 1. Tested web and SaaS applications across browsers, admin dashboards, and configuration-heavy interfaces, helping teams catch usability and workflow issues before customer impact 2. Performed manual, exploratory, regression, and UI/UX testing, uncovering edge cases that scripted tests often miss 3. Created clear, reusable test plans and test cases, improving test coverage and repeatability across release cycles 4. Logged high-quality bug reports with clear repro steps, severity, logs, and visuals—reducing back-and-forth with developers Automation, Playwright & Collaboration 1. Built and maintained Playwright (TypeScript) automation for critical user flows and regression scenarios 2. Used GitHub for version control, structured commits, and collaboration with engineering teams 3. Applied judgment on when automation adds value vs. when manual testing is more effective, keeping test suites reliable and meaningful API, Network & Security-Focused Testing 1. Tested REST APIs using Postman, validating status codes, payloads, negative scenarios, and error handling 2. Applied a network-security mindset (TCP/IP, DNS, DHCP, VLANs, ports, traffic flow) to identify misconfigurations and stability risks 3. Performed basic application security testing aligned with OWASP Top 10, focusing on risk rather than noise Hardware, System & Device Validation 1. Tested encoder/decoder platforms, firmware, and device WebUIs in hardware-integrated environments 2. Validated firmware upgrades/downgrades across Alpha, Beta, and production releases 3. Verified system behavior involving authentication, networking, and live data flows How Clients Describe My Work 1. Detail-oriented, investigative, and process-driven 2. Clear communicator with developers, product owners, and stakeholders 3. Reliable, security-conscious, and focused on real-world usage—not just happy paths Tools & Tech 1. Playwright (TypeScript), GitHub, Jira, TestRail, Postman, Wireshark, Python (test logic & validation), Agile/Scrum, CI/CD awareness Engagement Model I am open to freelance and hourly work and typically start with a small trial (~10 hours/week) to ensure a strong fit. Hours can scale based on results and project needs.

I help companies test, validate, and improve AI-driven and SaaS platforms before they reach customers. With 15+ years of experience in Quality Engineering, I specialize in testing AI-powered applications, SaaS platforms, APIs, and modern web products to ensure reliability, security, and great user experience.

Turning ideas into successful products, one project at a time. 👋 Hi, I'm Sitara. A few years ago, I joined a social networking platform project that had a big vision but many moving parts. Different teams were involved, priorities kept changing, and there was always pressure to deliver more features. By bringing structure to the project, improving communication between stakeholders, and keeping everyone focused on the right priorities, we successfully delivered around 80% of the planned platform features and transformed the idea into a working product used by real users. Experiences like this are why I love what I do. For the past 6+ years, I have been helping businesses turn ideas into reality through Project Management, Product Management support, Business Analysis, and Quality Assurance. I enjoy being part of the entire journey, from understanding business goals and defining requirements to coordinating teams and testing the final product before launch. My approach is simple: understand the problem, create a clear plan, keep communication open, and focus on delivering quality results. In addition to Project Management, I have 3 years of hands on experience in Quality Assurance, testing websites, mobile applications, and software products to ensure they work as expected and provide a smooth user experience. Here's how I can help: • Project Management • Product Management Support • Business Analysis • Agile and Scrum Project Delivery • Quality Assurance and Manual Testing • Website Testing • Mobile App Testing • User Acceptance Testing (UAT) • Requirement Gathering and Documentation • Bug Tracking and Reporting • Jira and Trello Management Industries I have worked with: • ERP Systems • E Commerce • CRM Platforms • Real Estate • Business and Finance Applications Certifications: • Project Management Professional (PMP) • Certified Scrum Master (CSM) • Certified AI Project Manager • Microsoft Certified Developer • Occupational Language Training in Project Management, Humber College Toronto When clients work with me, they are not just hiring someone to manage tasks or test software. They are working with someone who genuinely cares about the success of their product, pays attention to details, and stays committed from planning to delivery. If you have an idea, a product that needs improvement, or a project that needs strong leadership, I'd love to help make it a success.
