• Migrated a POJO microservice to Spring Framework• Designed a couple of software projects, including system performance enhancement, notification system for Operations team, environment monitoring & alerting, SQS queues monitoring & alerting, refactoring service by separating team specific logics, etc.• Designed, planned, presented, built, tested, and prepared to launch new Enrollment Sync system, which is a major project aimed to further improve the system performance by 50%. During this project, designed and developed 2 new services from scratch to support the system, which involves Spring Batch, Kafka, Temporal Tables, Data Migration, Data Sync etc.

• Formalized and applied working procedure for embedded team, including On-call, Releasing and other agile processes.• Standardized and implemented monitoring system for embedded team, including Prometheus metrics, Grafana dashboard, PagerDuty alerts, Slack notification, and other customized monitoring mechanisms.• Planned and created new RDS instances for team specific usage, and migrated databases to new instances. This largely improved system performance and team organization, and the pioneer documentation supported other teams to follow same procedure with much reduced effort.

• Designed and built E2E test automation framework, implemented it into various micro services, and integrated it into release build pipeline. This replaced most of the manual integration tests and largely promoted the project of cutting QA team.• Designed and built Test Data Auto Creation service along with various APIs, which supports manual execution via Postman and auto integration with a library. This helped reducing data creation time and complexity from 2 hours to 30 seconds.• Planned and pushed for Test Driven Development, which highly increased test coverage and encouraged testing culture.

• Participated a variety of projects focusing on Android development and validation:• Framework Development for Android Platform (Amazon Fire Phone) (APR 2013-FEB 2014)- Enhanced the custom Android Mobile Framework and implemented new custom APIs- Contributed on performance analysis and program optimization- Generated and performed Unit Tests to ensure the programming logic and product quality - Created sample programs to demonstrate product features• Graphics Validation for Android Devices (Intel chips) (MAR 2014-APR 2014)- Modified and executed automation tests and semi-auto tests on multiple platforms with required build and devices- Tested HDMI (High-Definition Multimedia Interface) with multiple monitors- Tested video/audio with analyzer; Track if display and frequency are both good• Quality Assurance for Android Platform (Amazon Fire TV stick) (MAY 2014-DEC 2014)- Prototyped the automation test design to assess product quality- Integrated automation test framework into build system and created validation scripts- Performed sanity tests and generated test report for required build and devices on daily base• Development for Android Application (Internal Project) (JAN 2015-MAR 2015)- Enhanced a puzzle game application using Alljoin technology (played upon multiple devices)- Troubleshot performance issues and provide hot fixes- Created Unit Tests to ensure the programming logic and product quality• Development for Embedded Application (Anaren Atmosphere) (APR 2015-PRESENT)- Created C code to wirelessly connect the embedded application to a Bluetooth smart mobile device- Implemented the application to Roomba-robot and remotely control the robot- Designed the UI

• Automation Testing System (team lead) - Proposed the system design to assess product quality automatically- Initialized Automation Testing framework on TeamCity (build system) - Enhanced internal tools to auto-generate test reports for any selected collection of functions - Generated and integrated test cases (e.g. Memory Leak, CPU usage, etc.) into testing framework • Mobile Development - Android & IOS (team lead) - Managed offshore team and weekly release process - Integrated Mobile APIs into core code and edited xml database file for new product support- Created scripts for release (e.g. creating release notes, downloading builds, database sorting, etc.)- Contacted application vendors for trial versions• Developer and Quality Assurance (engineer)- Implemented and tested new product support for selected SDKs (antivirus, system backup, P2P, etc.)- Created and updated test case documentation- Implied regression test for SDK methods using internal tools- Updated Beta Product Support Report weekly
