It’s December and in typical fashion I have left Christmas shopping too late. But as a developer, I can always use my coding powers to build a gift. Using Twilio Verify, I will code a small application that gifts a secret message to a holder of a specific phone number. This secret content could take the form of a message, picture etc. Watch out friends and family, I am going to be using it to gift my favourite holiday GIFs!

Ethereum is a blockchain with a cryptocurrency. As with Bitcoin, it costs users to send ethereum transactions, or interact with a smart contract (an on chain programme). The cost of these transactions is called gas, and the price can vary depending on usage. If lots of people are using the network, gas prices can get very high.

In my twenties, I worked as a Geography, my undergrad subject, and graphics teacher, slightly more tenuous, I had a product design A-level. Although there were some very rewarding aspects to teaching, the stack-loads of marking, and bureaucratic paperwork left me looking for other options.
Brushing up on my Graphic Design knowledge, I purchased a HTML & CSS textbook. I really enjoyed the process of making things. My highlights were those ‘Aha’ moments and small wins when it all finally worked. I started to consider web development as a career option.
Around this time I began to dip my toes into the London tech meetup scene. From my outsider's perspective, …
