NextUp - Text to Queue
Imagine driving in the car with a bunch of your friends or hanging out with them at your place listening to music on a speaker. One of your friends shouts "Hey can I play a song?" Now you are conflicted because your phone is connected to the speaker with your Spotify and your driving, you don't want to leave your phone unattended with your friend and you also can not queue the song that they want. What do you do?
Description:
With NextUp you can simply just tell your friends to share any song on Spotify through your text messages, and NextUp will automatically queue the song for all of you to enjoy. You can also easily setup restrictions on how many songs everyone can queue and how long they have to wait before they can start requesting songs again, that way everyone can make a contribution and be kept happy. With the simple interface, you can easily tell who queued which song and in what order it will play.
How to use:
1. Open up NextUp until you see the current song that is playing on your Spotify
2. Have a friend go to their Spotify and pick a song to request
3. Hit share, then SMS, then choose your contact and send
If you go back to NextUp, the song that your friend picked out should appear in the queue waiting to be played!
To queue more than one song at the same time, if your friends that are requesting are on laptops/tablets, all they have to do is: Hit the three dots next to the song, then copy song link, and include many of these in the same text message to you.

Active Ankle Prosthesis
Research Project
In this project I helped develop a powered two degree of freedom robotic ankle-foot prosthesis capable of dorsiflexion-plantarflexion and inversion-eversion. Unlike most existing powered prosthesis this device is more promising for regaining an agile gait which is lost after amputation. The actuation system is held in a fanny pack around the waist and it connects to the prosthesis using Bowden cables, allowing for optimized actuator placement while tailored to the users preference.
Description:
As the lead research assistance for Prof. Dallali over Summer 2018, I helped start bringing to reality a research idea that Prof. had presented in various research conferences. This unique experience in working in the nexus of biotechnology and electrical engineering allowed me to put to good use the various concepts I had learned about systems and control in the classes I had taken the year previous. Persevering through the summer, we had gone from not being able to run a linux development environment for the LabView tailored National Instrument microcontroller to being able to control a stable motor system that will eventually be used in the prosthesis. I was able to control, track, and analyze the movements of the motors to a very fine level of measurement as we should be able to especially in a prothesis.
This experience taught me so much about how to learn during the job, and to solve one problem at a time in order to reach the bigger goal. Being able to start this project from the beginning gave me the opportunity to witness the growth of a project that had cutting edge technology and real impact in the world.
Skills Developed:
- Learned to code algorithms and interface with microcontrollers in C
- Used NI myRIO, ESCON Motors and drivers to build assembly
- Implemented several feedback control loops with tracking capabilities ex: PID

Amphibiaweb
Android App
With this project, my close friend and I were chosen as student developers to create a mobile version of a database lookup site that is run by the UC Berkeley Museum of Vertebrate Zoology. We are currently going through the different phases of mobile application development from designing, prototyping, implementing, and refining. We are looking to release this application in the Spring of 2019 for use by amphibian enthusiasts across the world.
Description:
Through this project, I learned how to work well with a fellow developer and friend when it comes to coding an app together. We really took advantage of planning thoroughly before starting to implement large features. I had a fun time learning how to set up a productive work flow from scratch to make a small group effort not only effective but also easy.
Skills Developed:
- Java
- Android Studio
- Git
- Productive team workflow with splitting tasks and writing modular code

OpenDorm
Berkeley Robotics Competition
OpenDorm is a reimagination of the most fundamental way people do things together. Bridging the physical component of going door to door with the technical integration of RGB light, LCD screen, and app integration, we foster a more welcoming and social dorm experience.
Description:
This product ultimately will be an improved method for creating spontaneity, no longer needing to message a group text and wait, but instead finding new groups to do new things. We modeled seasonal/event based themes, whether it be not having to buy Christmas decorations to celebrating Cal’s win over Washington State.
Skills Developed:
- Furthered knowledge about arduinos, sensors, actuators
- Worked on public presentation skills as we pitched the idea
- Worked on a team delegating tasks in various fields of expertise
