Research Assistant

As a research assistant, I have developed Android applications and applied ML at the Systems and Technology for Medicine and IoT (STMI) Lab , mainly using Java, MATLAB, and Python.

• I developed a wearable data collection app in Android that collected IMU sensor data and sniffed BLE signals as a proxy for location which also let user's annotate data at will.
• I applied ML techniques in the data collected from a watch for posture recognition and detection of eating moments. I also worked with ML techniques to estimate blood pressure from other physiological signals such as pulse transit time.
• I was the lead author on "A Human-centered Wearable Sensing Platform with Intelligent Automated Data Annotation Capabilities", a paper presenting the wearable data collection app tested on a diet monitoring experiment and accepted at IoTDI 2019.

Kwan Tecnologia

Software Engineer - DevOps (Innovation team)

I joined the company as a software engineer developing features in the innovation department using MEAN stack. However, I worked mostly on the back-end side and database management. When the time for deploying the new app arrived, I was requested to manage the process and then I became the DevOps of the team, however, I kept developing features. The company I was working for also worked with companies in the US. Three months before I left the company to pursue my Master's degree I was asked to join a team from Agralogics (CA, USA) to work remotely as a DevOps as their current DevOps had left the company.

• I built a web app for coupon management using MEAN stack and Mocha for unit testing as part of the Innovation Group.
• I managed the MongoDB database and was responsible for creating scripts to access the data efficiently in a geolocated setting.
• I set and managed continuous integration using Jenkins to automate the testing and deployment process.
• I created and managed AWS instances for diverse development environments.

DevOps (Agralogics)

• I performed DevOps tasks remotely for Agralogics (CA, USA).
• I found and addressed undocumented bugs in the AWS deployment pipeline, saving developers 1 hour per release.
• I maintained the web app deployment environment and existing automation scripts and created new app instances to match team needs.
• I worked with bash/python/ruby scripts, Git, Jenkins, and Docker containers.
