PROFESSIONAL EXPERIENCEFreelance Tech & QA Projects (Logistics, Web3 & AI) QA Engineer (Manual + Automation) | October 2024 — Present Full-Cycle Manual & Automation QA: Balanced meticulous manual exploratory testing with automated script development for complex web and mobile platforms, ensuring seamless user experience and technical stability. Logistics Application QA (Truck Parking Platform): Deep-dived into complex multi-tier pricing structures, booking matrices, and tax calculations for a high-load logistics booking app. Conducted extensive manual logic validation and wrote automated Python scripts to validate dynamic JSON datasets against backend API schemas. E2E Test Automation (Playwright & Python): Built and maintained scalable automation suites for core web flows usingPlaywright, Pytest, and the Page Object Model (POM), automating repetitive manual regression scenarios. Mobile Cross-Platform Systems: Executed end-to-end manual and automated checks across iOS and Android (real devices and emulators), verifying touch gestures, responsive rendering, and mobile UI layouts. Next-Gen AI & Web3 Verification: Performed manual and automated verification for Web3 features (crypto wallets, checkout flows, blockchain UI state callbacks) and AI tools (prompt validation, response relevance, chatbot boundary limits). Shifton QA Engineer (Manual + Automation) | April 2024 — October 2024 Full-Cycle Product Testing: Executed functional, UI/UX, regression, smoke, and sanity testing for a complex workforce scheduling SaaS platform, validating major releases, permissions, and rapid hotfixes. Manual & Automated API Testing: Tested REST API endpoints and GraphQL queries using Postman and Swagger/OpenAPI, inspecting JWT/Bearer authentication, status codes, and validating JSON Schemas. Performance Verification: Configured application load and stress tests using Apache JMeter and RedLine13; tracked application stability and server metrics via Prometheus and Grafana dashboards. QA Documentation & Process: Authored structured test plans, comprehensive checklists, and detailed Jira bug reports with exact network payloads and steps to reproduce, streamlining developer resolution times. Independent Tech, Crypto & AI Explorer Self-Driven Technical Experience | 2023 — Present (3+ Years) Dual-Perspective Quality Approach: Cultivated a strong hybrid mindset—analyzing application logic deeply from a manual tester's perspective to find edge cases, while simultaneously designing automated scripts for sustainable defect prevention. Environment & Network Analysis: Utilized Docker containers, Linux commands, and Charles Proxy to trace asynchronous network traffic, analyze payloads, and inspect client-server interactions.
