I started programming on the ZX81 - 1kb RAM with a 3.5MHz Z80A CPU. Most recently I was developing and running a cluster processing 60 billion transactions daily with a 99th percentile latency less than 10ms, with data being visible in a Hadoop cluster within seconds.
I now program in a wide variety of languages: HTML5/JavaScript/CSS3, Python, Java. Over the years I have also extensively used SQL, ML and rules-based rete engines.
I have spent the last few years deploying and operating large-scale solution in the AWS cloud and managing a talented and highly effective Agile Devops team.
