Professional Experience

Senior Machine Learning Engineer

Klue | Vancouver, Canada (01/2023–Present)

• Lead projects involving multiple teams, ensuring project goals align with business needs and identifying potential blockers early.
• Build an LLM application with prompt management and Retrieval-Augmented Generation (RAG), improving user engagement by 25% and reducing the time to value by 49%.
• Implement a solution for news grouping, reducing content overlap by 40%. Developed a custom online clustering algorithm and ensured data consistency across distributed systems.
• Develop a subscription-based scraping service, reducing manual labor by 81%.
• Create a pipeline for transcript annotation using WhisperX, cutting transcription costs by 46% and increasing accuracy by 5%.

Machine Learning Engineer

Klue | Amsterdam, Netherlands (01/2020–12/2022)

• Designed and implemented the document pipeline, processing hundreds of thousands of news items daily for thousands of clients.
• Developed a rule-based management & filtering system using boolean logic, providing configurable filtering rules.
• Created a junk filtering solution based on a custom Named Entity Recognition model and a tree-based classification model. We compared labeling services, created custom datasets, and trained models, resulting in a 93% reduction in irrelevant content.
• Built a topic tagging system using multi-class, multi-label deep learning models, increasing user retention by 21%.
• Oversaw data handling, metrics definition, model tuning, and deployment, while monitoring performance across all projects.

Research Intern

Philips Lab | Amsterdam, Netherlands (02/2019–09/2019)

• Improved parameter efficiency and robustness in vision models, culminating in the paper "Affine Self Convolution."

Computer Vision Intern

Bosch | Cluj-Napoca, Romania (02/2016–05/2016)

• Improved the scale sensitivity of an existing object detection solution by implementing techniques inspired by the "Fastest Pedestrian Detector in the West" paper. Learned about scale invariance and object detection.

Publications

• Learning to Convolve (Main Author): ICML 2019 - Amsterdam, Netherlands (02/2019)
  Developed a method to learn transformations in group convolutions, enabling filters to adapt to transformations and reducing sensitivity to input rotations.

• Affine Self Convolution (Main Author): Philips Lab - Amsterdam, Netherlands (11/2019)
  Introduced Affine Self Convolution, which uses data-dependent filters for image processing, combining self-attention with convolution to improve accuracy and parameter efficiency.

Education

Getting started with GitHub Apps

Welcome to Getting started with GitHub Apps

We're going to work together to learn about GitHub Apps! We'll do this in this repository, which is a collection of resources - games to be specific. Before we start using real GitHub applications, let's get some foundations out of the way.

New to GitHub?

For this course, you'll need to know how to create a branch on GitHub, commit changes using Git, and open a pull request on GitHub. If you need a refresher on the GitHub flow, check out the Introduction to GitHub course.

Application vs GitHub Application

There are many types of applications, like the apps you might have on your phone. In this course, we'll focus on GitHub Applications, apps designed to work on GitHub.

GitHub Apps allow you to change GitHub's surface-level functionality through webhooks and GitHub's APIs. GitHub Apps act as top-layer tools that you can use to customize and automate routine processes.

Please note that GitHub Apps are very different from OAuth Apps. These have a different installation flow and have different rules around how they handle their data and access. If you'd like to learn more, check out the documentation on the differences between GitHub and OAuth Apps.

Step 1: Get familiar with GitHub Apps

To learn more about GitHub Apps, you will install two on this repository. Make sure to install the apps on this repository only. Don't apply them to everything you have access to.
