Work Experience

Senior Python Web Scraping Specialist

2022 - 2022
Number Five House Ltd
  • Developed and deployed a web scraping pipeline with Python and Selenium.
  • Collected profile and network data from a large online social media platform.
  • Performed ETL on the data. Used network analysis and machine learning to enrich collected information.
Technologies: Python, Web Scraping, Google Sheets API, Google Sheets

Undergraduate Researcher

2021 - 2022
Imperial College London
  • Built a TensorFlow machine learning pipeline using Python to predict the properties of high-energy X-ray pulses at ultrafast rates.
  • Deployed machine learning pipelines to the university's high-performance computing cluster using Secure Shell.
  • Developed simulations of quantum many-body physics in Python and devised a new measurement scheme to analyze simulations.
  • Used advanced statistics and machine learning, including restricted Boltzmann machine neural networks, to extract knowledge from our simulations.
  • Co-authored two papers currently in preparation, both applying machine learning to different physics regimes.

Research Intern

2020 - 2020
The Institute of Cancer Research
  • Developed an unsupervised learning pipeline to analyze genetic risk factor pathways for brain tumors in adults.
  • Programmed and debugged R and Python to contribute to interdisciplinary research.
  • Implemented my pipeline on a high-performance computing cluster.
  • Updated the legacy code to use Python 3 instead of Python 2.
  • Performed tissue-specific analysis to find significant risk factors that would not be recognized as significant without accounting for tissue differences.

Cross-platform Social Sustainability App

Created a full-stack cross-platform app with a Flutter front-end and TypeScript back-end, connected with a GraphQL API. I built the database on top of PostgreSQL, programmed the back end in TypeScript, and used Firebase for the real-time database, pop-up notifications, and user analytics. Additionally, I enhanced the analytics by using a custom asynchronous data pipeline, which performed k-nearest neighbor analysis to group users into different, dynamically set categories.

Webscraping Tutorials in Python

A set of tutorials for beginner, over intermediate to advanced web scraping in Python using Selenium. The tutorials are written as little challenges, and solutions, as well as explanations, are provided. This project is still ongoing, and I am working on further tutorials to expand toward highly advanced web scraping problems.

Bayesian Analysis of Stock Market Data

Using Excel, I worked on a Bayesian approach that an investment company utilized to predict the likelihood of a recession occurring in the near future, given key market parameters and a decade-long history of market data. As this was just after COVID-19 was brought under control, this was a highly relevant subject, and the employer was more than happy with my work.
