Experience

StudJobs

As a young student in university, I found a common issue among my classmates, we all needed money to pay rent and other expenses. With two classmates willing to learn new things, we created a platform using React and Node.js, targeted at students looking to do small jobs such as babysitting, gardening, cleaning, or even part-time jobs. We encountered numerous issues that we did not stumble upon before and learned a lot about web development from how to deploy code to production to the best ways to store data, and many other essential programming tips and optimizations.

Binance Trading Bot

A Node.js back end that can receive buy or sell orders from the TradingView strategy via their Alert API. There are already some solutions out there but they are subscription based and offer many more features that I didn't need.
