About Me
I am a currently a Staff Software Engineer at Trend Micro with interests in cloud native technologies, solving complex problems, and designing resilient scalable solutions.
I thrive at multi-tasking and creating innovative software solutions to complex issues. I work best in a fast-paced environment with the right balance of independent and collaborative work. Through school and industry experience, I have gained extensive experience in the software life-cycle including development, documentation and testing.
In my free time, I am an avid YouTube subscriber, watching everything from funny cat videos to daily bloggers. I also spend some of my personal time working on personal projects that integrate software and hardware using microcontrollers, in addition to occasional bike rides.

Experience
Staff Software Engineer
Trend Micro
Mar 2021 – Present
• Founding developer of Cloud One Open Source Security by Snyk. Implemented custom SAML identity provider to allow single sign to a Snyk partner application using Trend Micro Cloud One identities.
• Improved product time to value by developing dynamic security rule deployment mechanism to allow runtime protection rules to be updated in customer environments automatically using AWS IoT.
• Drove initiative to create 12+ operational playbooks for responding to operational monitoring alarms, and for troubleshooting service issues.
• Helped create and review architecture designs for new Cloud One Container Security features.
Full Stack Developer
Trend Micro
Mar 2020 – Mar 2021
• Designed, developed and operated cloud native security application written primarily in Golang through a microservice architecture.
• Used event driven and REST API based architectures to achieve a high level of scale and modularity according to best practices.
• Leveraged the Serverless Framework for deploying complete software system (application code, infrastructure, monitoring, etc.) as code to AWS.
• Mentored new team members by providing pair programming opportunities, answering technical questions and performing 10+ code reviews per week.
Continuous Integration Developer
Trend Micro
June 2018 – Mar 2020
• Design, develop and maintain industry standard CI/CD infrastructure through the use of Jenkins, GitHub, Docker, AWS, Azure, and Atlassian collaboration tools.
• Provide operational support for Trend Micro's Deep Security as a Service (DSaaS) through the use of various AWS infrastructure (OpsWorks, EC2, RDS, Lambda) and monitoring tools.
• Advocate for an increase in DevOp's culture and practices in all aspects of the software lifecycle.
Software Engineering Intern
Ciena Corporation
May 2016 – Sept 2017
• Contributed to the software cycle of a feature implemented on a real-time system to visually display hardware LED status in a customer visible user interface.
• Significant experience debugging user space software errors on Windriver VxWorks, and Linux OneOs with the use of GDB and LTTng tracing.
• Analyzed product performance issues by using memory and real-time monitoring tools to identify software deficiencies. Leveraged open source analytics platforms such as Elasticsearch and Grafana to easily identify the impact of LTTng tracing on a real-time system.
• Increased efficiency of feature integration and regression testing by developing a generic automated test suite in TCL. Tests are now created and executed dynamically based on data queried from the product’s evolving data model.

Projects
Human Mapped Robotic Arm
Fall 2017 - Winter 2018
Fourth year capstone project that used sensor fusion to combine 7 electronic sensors mounted on a custom made arm exoskeleton. Sensor exoskeleton allows motion of shoulder rotation, elbow flexion/extension, wrist flexion/extension, wrist pronation/supination, and hand grip extension to be mapped to a servo motor based robotic arm. Project won 2nd place prize out of a total of ~25 electrical engineering projects.
