I'm a developer who's spent my early professional years writing .NET, then quite a bit of time wading through various PHP frameworks with MySQL and PostgreSQL, then a few more years mired in MERN and MEAN, and more recently maintaining legacy Java systems backed by MongoDB while building new microservices with Go using DynamoDB and Redis.
I occupy much of my spare time exploring Linux, Perl, some open source projects, and various academic Computer Science and Math type things.
