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.

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.

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.
