• Built a distributed spatio-temporal scraper for mission-critical data (i.e. training our AI models and other downstream tasks)
• Generated synthetic datasets for training our AI models on data source modalities that were scarce in volume
• Interviewed, hired and onboarded prospective SWE and DE candidates to help our data needs
• Fine-tuned open-source models to assess its performance on spatial reasoning tasks

• Interviewed over a dozen candidates to grow our engineering team in response to company growth.
• Implemented a trigger-word, fuzzy-search-based algorithm used to respond to incoming SMS as a failsafe to our NLP frontline.
• Led the migration of our toll-free messaging service from Leadwire to Twilio
• Co-designed and co-led the integration of the company's 3rd messaging provider: Bandwidth
• Co-led the migration of our company's voicemail storage service from Twilio to GCS in order to reduce operational costs
• Implemented a solution to rising SMS segment costs by removing non-GSM-7 characters and "casting" emojis and other special characters to their corresponding "verbose names", resulting in about $10k to $20k in monthly.

• Developed a web application at the CDCC (Centro de Desarrollo y Consultoría Computacional), under the guidance/mentorship of Dr. Carlos Corrada, using the LAMP stack.
• The web app served as a sort of Admin Tool that helped the client, Dr. Juan Ramírez, connect and assess students that participated in REUs. (Link: https://tania.uprrp.edu, Code.
• Refactored and documented the Android app extensively to improve readability and maintainability. (Code: https://git.ccom.uprrp.edu/Marle/android)

• Developed and assessed Deep Learning models for segmentation and characterization of ETEM images of nanoparticles under the guidance of Dr. Rémi Mégret.
• Designed and built a system for robotized image capture using the Raspberry Pi 4 Model B along with the Arducam IMX298 by providing a simple GUI made in Tkinter to view the camera's stream, handle image captures and.
• Built a web app from which the user could view the image stream, set the focus and capture images the Raspberry Pi's file system. Also provides access to the captured images.

• Participated on a 2-week Machine Learning bootcamp which included discussion about unsupervised, supervised and reinforcement learning.
• Developed a convolutional neural network based on U-Net that applies segmentation on diffraction patterns to identify artifacts in huge images (2048 x 2048).
• The CNN model code is being evaluated in order to integrate it to the preexisting NSLS-II BlueSky infrastructure to perform the automated masking in real time, which would save scientists time and effort.
• Wrote a preliminary paper and a corresponding poster, which I presented to my mentors & peers during the last week of the internship.
• Wrote a project proposal with peers to develop a tool to help people be aware of COVID hotspots in USA.

Worked with the mechanics of the unbraiding of DNA molecules in the lab of Dr. Edwin Quiñones. Specifically, we made torque, force, angular velocity and other types of dynamic variable measurements. We basically bind one end of the double–stranded DNA to a glass surface, then attach superparamagnetic beads to the other end, to which we apply a magnetic.

The BNL Scientific Computing College Internship prepared interns to solve the big data challenges facing researchers in science, technology, engineering, and mathematics (STEM). The interns absorbed a full academic course in three weeks while completing 90 lab assignments and a research project. Some of the skills learned included parallel processing, 3D.
