Worked within globally distributed QA teams to ensure consistent software quality across Xiaomi Android OS, applications, and network functionalities on Qualcomm and MediaTek platforms.

• Improved telecom feature reliability (ECC, VoLTE, VoWiFi, USSD, eSIM, and supplementary services) through structured QA strategy and expanded test case coverage.
• Drove release quality across concurrent smartphone projects by identifying and resolving 350+ cross-layer defects spanning modem, system, and application domains.
• Ensured smooth 3G phase-out and VoLTE/VoWiFi rollout by supporting coordination between TAM, technical teams, and telecom operator teams.
• Enhanced product usability by driving structured testing with the Language Localization Center, reducing localization defects and after-sale customer complaints for MIUI & HyperOS.
• Identified, tracked, and resolved Google Mobile Services issues (Google Play, Google Dialer, Google Discover, YouTube, Android UI, Gemini) across multiple MIUI releases and projects.
• Deployed automated regression testing and expanded test coverage using a risk-based strategy.
• Maintained timelines through structured defect resolution and efficient test/inventory coordination while mentoring new engineers and driving SOP improvements.
• Developed a shared inventory management workflow for testing resources, improving traceability and coordination across testing, product, and engineering teams.
• Awarded consecutively for quality work across multiple flagship products.

Performed field, mobility, localization, and system acceptance testing across network firmware, system software, and application layers to ensure release quality and functional stability of Vivo smartphones.

• Improved network and application compatibility through identification and resolution of ~100 cross-layer defects across concurrent product releases.
• Optimized execution and automation for field, localization, acceptance, regression, and exploratory testing across GSM/UMTS/LTE, IMS, VoLTE/VoWiFi, and dual-SIM scenarios.
• Ensured release confidence by validating compatibility across top third-party applications and operator features, improving overall localization quality.
• Reduced after-sales complaints through market data analysis, issue reproduction, structured defect triage, and close collaboration with engineering teams.

Worked on multiple product development ventures, where real-world delivery challenges reinforced the importance of structured testing and quality assurance.

• Built an iOS news app (Objective-C) with backend publishing integration, focusing on data integrity, structured testing, and reliability across content updates and user behaviors.
• Developed an eCommerce website using API gateway and load balancer patterns, strengthening focus on REST API/integration testing, failure scenarios, and system-level QA.
• Mentored teams in building mobile apps with Firebase services, introducing structured testing and release practices that contributed to one team winning the national Technovation competition.
• Set up and maintained Linux environments for testing and validating C/C++ system-level applications.

Project: LUKS & LVM Support for Calamares & KDE Partition Manager

• Extended Linux storage subsystems (LVM, LUKS) support across three open-source C++ projects.
• Designed algorithms and abstract interfaces for LVM, RAID, and encryption functionality using cryptsetup and lvm2 to keep code modular and maintainable.
• Implemented and tested new functionality, updated Qt GUI dialogs, and ensured module compatibility with Calamares and KDE Partition Manager.

• Organized and hosted bi-weekly community events across venues, coordinating speakers, venue teams, and organizers.
• Owned pre-event validation of AV setups (sound, lighting, projection), identifying risks early and troubleshooting before live sessions.
• Acted as central coordination point during events, handling real-time incidents to keep execution smooth under time pressure.
• Strengthened structured problem-solving, quality mindset, and communication of technical issues for non-technical stakeholders.
