    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.

    Ahoy there!

    Ex-teacher turned developer turned developer evangelist checking in. It’s been a winding road to my destination at Twilio, via meetups, bootcamps and hackathons. This is my journey from classroom to (online) conferences.

    From teaching to coding

    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.
