Cyrus Chan

• Spearheaded AI/ML integration by deploying scalable deep learning action recognition models on AWS SageMaker and embedding an AI Code Agent along with MCP servers into CI/CD pipelines—automating code generation, bug fixes, and workflows. Enabled support for MCP-compatible clients, significantly boosting deployment efficiency and streamlining ticket management. • Architected and engineered robust serverless cloud backend solutions for IoT devices using AWS CloudFormation and diverse AWS services, establishing scalable infrastructure for Cypress and Sentinare Sensors. Applies principles of event-driven architecture, containers, and Kubernetes to build highly scalable, resilient, and agile applications optimized for modern cloud environments. • Engineered critical IoT features, including a secure skeleton data-only recording and alert event system for Sentinare sensors (reducing storage costs) and Alexa integration for smart home device control (Alexa Together service). • Developed a ReactJS-based web tool for managing OAuth access control for third-party client integration and an internal admin tool, streamlining security and operational efficiency. Provided direct technical support and collaborated closely with third-party companies to facilitate their integration with the Sentinare platform.

• Architected and launched a robust VoIP Server, concurrently developing the voice communication feature within cross-platform iOS and Android applications in .NET framework and within the Cypress Sensor in C++. Additionally, enhanced device accessibility and control through integrations with Google Assistant and Alexa for smart home functionalities. • Designed and optimized MySQL and MongoDB database schemas, ensuring efficient data storage and retrieval for critical applications. • Developed secure RESTful API backends with OAuth 2.0 authentication and push notification features for Android/iOS, creating comprehensive documentation to facilitate third-party integrations. • Integrated Altumview face recognition and object detection C++ native libraries into Android applications via JNI, enabling advanced mobile functionalities.

• Developed Selenium-based end-to-end tests to validate UI workflows and interactions between message converters and web interfaces. • Wrote unit and functional tests for an object-oriented Java application, leveraging its modular design to improve test coverage, maintainability and effective debugging of the message converter codebase.

• Authored detailed test cases with diverse scenarios, significantly increasing test coverage and ensuring new features met acceptance criteria. • Maintained critical test data and provided accurate expected results, actively supporting team members in software testing efforts. • Identified and investigated the root cause of critical bugs through systematic code debugging.
