Job Experience

Mar-2022 to Present

Software Developer, Vancouver, CA

Nasdaq, Verafin

  • Improved query performance by visualizing execution plans, analyzing execution plans and optimizing queries.
  • Conducted log analysis through Splunk to solve the agent's problem on customer side.
  • Built new features on agents using different design patterns to monitor different types of anti-money laundering and human trafficking and conducted unit and qa testing (salesforce).
  • Built an ad scrapper using selenium and 2captcha to bypass captchas and scrap needed information on some largest escort sites to fight human trafficking.
  • Configured AWS Elastic MapReduce (EMR) jobs through Terraform and orchestrate them on a step function.

Oct-2021 to Feb-2022

Data Scientist, St.John's, CA

Nasdaq, Verafin

  • Built the whole data analysis pipeline (e.g., exploratory data analysis -> optimized deep convolutional generative adversarial networks -> local interpretable model-agnostic explanations) and database through SQLite for the classification problem.
  • Augmented image dataset from 150 images to 2500 images by optimized deep convolutional generative adversarial networks (DCGANs) utilizing spectral normalization, label smoothing regularization, instant noise, and relativistic loss functions.

Jun-2020 to Feb-2021

Research Associate, St.John's, CA

Northern Region Persistent Organic Pollution Control Lab (NRPOP)

  • Conducted exploratory data analysis (EDA) after cleaning datasets and Implemented principal component analysis (PCA) for dimensionality reduction and feature extraction (from more than 800 features to less than 12 features).
  • Applied 6 different machine learning methods (KNN, SVC, RFC, DTC, EVC, LRC) to build models and reached the highest f score of 0.9.
  • Built the whole data analysis pipeline for the classification problem and database through SQLite for increasing dataset size in the future.
  • Created the website by Flask to deploy machine learning models for the end users.

Jun-2019 to Sep-2019

Student Data Integrity Research Assistant, St. Johns, CA

Alumni House, Memorial University

  • Analyzed data and verification within the alumni SQL database.
  • Sourced, cross-referenced, and updated biographical information from internal/external sources for alumni and friends of Memorial University using SQL query.
  • Maintained the relationship with alumni and donors.

Feb-2019 to Nov-2019

Research Assistant, St.John's, CA

Memorial University

  • Extracted carbohydrate, protein, and fat from substrates.
  • Conducted hypothesis test on the theoretical yield and the experimental yield.
  • Interpreted correlation and regression analysis with the theoretical yield and the experimental yield.

Dr. Bing Chen

Professor and Head, Department of Civil Engineering

Alex Chen is a diligent and intelligent graduate student under my supervision. Working with him in the past three years, I am impressed by his research skills and relentless improvement. I trust he will be successful in industrial field.

Dr. Noori Saady

Professor, Department of Civil Engineering

I have known Mr. Alex Chen since the beginning of 2019 in my class "ENGI 9628 Environmental Laboratory". Alex Has shown to be clear and persistent in his objects. He is well organized and interacts well with his colleagues. His past and present academic accomplishment are good indicators of his strong skills. I expect that he will successfully accomplish his academic objectives at MUN and achieve a successful work career in the future.

Baiyu (Helen) Zhang

Professor, T2 Canada Research Chair

I have co-supervised Alex Chen since 2019. During my supervision period, I find him to be a team member and responsive individual. He listens very well to other points of view and incorporates them into his work and he also has leadership qualities.
