My current project is a cryptocurrency trading algorithm. Previously I built an Ethereum mining rig as an experiment and used it to mine several different coins. I always knew it would be a short-term operation as proof-of-work mining comes to an end, but I wanted to continue earning passive income from cryptos. The way forward is a combination of earning rewards for owning various coins (proof-of-stake), and automatically trading coins as their currency pairs fluctuate.

This is currently a work in progress - watch this space.

I'd been looking for a personal project to build in Go for a while, but in order for me to invest time into it, it needed to be something that would be useful in my everyday life. At the time, I had become frustrated with the limitations of managing my money in Monzo and across various pots. I knew Monzo had a customer-facing API open to all, so I decided to see what I could do with it.

After some experimentation, my Go project ended up as an automated tool where I could set my goals (i.e. save up for this purchase, or pay off that credit card, etc) and have it manage my money for me. Each week, depending on how I was progressing towards my financial goals and what my spending had been like, my project would parcel out money into the various pots.

I paired this with Monzo Premium's virtual cards, so I could only spend what was available in each pot as determined by my code. I setup pots for various purchases I wanted to make, pots for health, holidays, disposable income, bills, and so on. The next revision of this project will likely be something that analyses my spending and points out areas where I can make savings, i.e. on subscriptions I rarely use.
