About me

Hey! I'm Isaac, a software engineer. I started programming when I was about 13 years old, fell in love and haven't stopped since. I spent a lot of time automating everything I could think of automating, from finances to sports arbitrage, and ended up where I am today.

My passions lie in technology, personal finance and the environment, and I love tinkering and building things! I'd love to start a conversation with you, so please get in touch!

In the meantime, scroll on to learn about my work and projects.
