Senior Test Automation Engineer / SDET

I lead QA strategy and blockchain test automation initiatives. I architect comprehensive testing frameworks focused on the security, scalability, and performance of decentralized systems.

I developed an autonomous DEX trading bot in Python. I used AI-assisted development to optimize algorithmic trading strategies and support rapid iteration.

I engineered CI/CD pipelines in Tencent Cloud and performed advanced fuzz testing of zero-knowledge circuits using Rust. I also adapted the Ethereum/Hive Eth2 codebase to meet infrastructure requirements for the Taiko network.

I designed and implemented a custom automation framework using Hardhat and Ethers.js to validate smart contract integrity across the Aurora ecosystem. I built a high-performance state injection system to populate blockchain environments programmatically and reduce test execution cycles.

I integrated Datadog observability and GitHub Actions automation to provide real-time performance insights and feedback for the Rainbow Bridge and related protocols.

I coordinated a global QA strategy and implemented Playwright-based end-to-end automation for complex browser interactions. I built scalable stress-testing infrastructure with GitHub Actions and conducted detailed pull-request reviews focused on unit-test coverage, security, and architectural consistency.

I architected QA strategy for the Mantis Ethereum Classic client and created high-fidelity network simulations using Nomad and Docker to validate protocol stability. I developed large-scale performance and load testing frameworks for smart contracts using Hyperledger Caliper and OpenZeppelin standards.

I orchestrated Buildkite CI/CD pipelines for Mantis integration with the Ethereum/Hive ecosystem. I also re-engineered devp2p/eth test suites in Golang to improve execution speed and network reliability.

I engineered automated REST API test suites and refactored Android components to support comprehensive unit-testing frameworks. I also developed automation protocols for real-time Bluetooth communication between mobile devices and hardware peripherals.

I developed high-performance Android applications with robust architecture and API integration. I collaborated with design and backend teams to deliver maintainable, feature-rich mobile solutions.

I led the modernization of a legacy Android application by migrating it to a reactive MVVM architecture using Kotlin. I decoupled network and persistence layers and implemented unidirectional data flow with LiveData and Coroutines, reducing technical debt and improving stability.

I architected automated mobile testing frameworks using Espresso and built REST API test suites with Groovy and Spock. I maintained CI/CD servers and delivered internal technical training and tool-development initiatives.

I developed scalable Android modules and optimized application performance. I implemented core features and performed rigorous testing across diverse device environments to ensure application stability.

I directed Android development initiatives and provided technical consulting. I balanced project delivery with independent R&D to evaluate and integrate emerging technologies into development workflows.

I developed and unit-tested Android Wear applications, with emphasis on state persistence and UI components.

I developed an Android Wear application featuring speech recognition, real-time translation, and speech synthesis. I gained practical expertise in Android activity lifecycles, services, and communication between wearable and phone applications.

I managed Linux server infrastructure and provided technical support for a university department.

Bachelor's Degree in Computer Science.
