I'm Nicholas Yek.

a.k.a the 

The use & development of technology reflects our values.

So, my focus is on making interesting technology;
Tech that’s well-designed, effective, and empowers communities.

My academic interests: computing systems Embedded & Operating Systems ​, high performance computing Parallelism, Concurrency, Distributed Systems ​ and intelligent things Automata theory, AI/ML & computer networks ​.

I’m particularly interested in exploring intersections between theory and practical computing systems.

PROJECTS 🔧

We are what we eat build. I have curated projects @ the projects tab, but these are my favourites…

  ResistorPrediction 🤖

Executive Summary:
An experimental attempt to predict resistor values based on pictures of resistors. Powered by machine learning and OpenCV. Achieved up to 60% accuracy in predictions (not exactly production ready).

🚧 Project write-up in progress…

  FindNUS 🔭

Executive Summary:
Awarded the highest level of achivement, given to the top 7% of teams (top 29 of 414 teams) for NUS School of Computing’s 2022 iteration of Orbital.

FindNUS is a lost and found web app built during Summer 2022 Orbital. As the backend developer, I built a RESTful API backend using a microservices architecture. Apart from regular CRUD, we also used some NLP and fuzzy searching to help lost people find their lost stuff.

  SnipNScan 📷

Executive Summary:
Using OpenCV and Tesseract, I built a QR code and text scanner because too much text in this world is embedded in images and are un-copypasteable. Think of images of code.
