I’m a Data Scientist
I’m passionate data scientist who has an insatiable hunger for knowledge and has demonstrated his expertise through his various rankings in international data science and machine learning competitions.
I’m interested in the field of machine learning in general, NLP, data engineering, and data infrastructure and architecture.
Here are a few technologies I’ve been working with recently:I worked on the following two projects:
The GNSS project needed deep domain knowledge which pushed me to learn numerous new concepts and strengthen myself in others including: Kalman filters, nonlinear optimization, how satnav systems work from a physical prespective using pseudoranges, signal identification by PRN codes, Keplerian elements transmitted by satellite messages, frames of reference, and many more.
For the vehicle inspection system, I worked on different steps of the ML pipeline from modeling by fine-tuning pretrained Mask-RCNN and ResNet-50 models in Tensorflow, to the optimization of the model training loop, to the preprocessing and merging of different datasets using custom scripts, and finally, to the manual annotation of hand-picked data for testing
My focus was mainly on using data science in cybersecurity.
I worked in setting up threat intelligence platforms (TIPs) such as MISP and OpenCTI. I then transitioned to work with Kibana, a data visualization dashboard software for Elasticsearch.
This specialization is taught by Dr. Andrew Ng, an adjunct professor at Stanford University; founder & CEO of DeepLearning.AI and Landing AI; and chairman and co-founder of Coursera.
It consists of the following 5 seperate courses (which, combined, take about 180 hours to complete):
