Here be settings.

Yes, this is a fairly large box considering the low number of settings. One could even go so far as to say it could be more appropriately called "Page Setting".

Page Info

The decision to use just regular HTML, vanilla JS (mostly), and vanilla CSS to create this page was made as I didn't want to pick a specific framework.

I think sometimes developers get too attached to their framework of choice, and can get tunnel vision when trying to decide what to use for a new project.

Generally I'm framework agnostic as they all have their pros and cons.

A Little Bit About Me

Recently, I have dedicated my efforts to collaborating with teams on developing dynamic, client-facing frontend applications, seamlessly integrating with robust backend APIs.

I take pride in empowering my team to take full ownership of the product lifecycle—from the initial vision and design through to architecture, infrastructure configuration, deployments, and comprehensive monitoring and observability.

I am passionate about mentoring and teaching, and I'm eager to join a role where I can continue guiding colleagues through professional and personal growth, helping them overcome challenges and hone their skills.

I am eager to join a forward-thinking organization that embraces modern application development, where I can drive innovative feature enhancements, explore emerging technologies, and tackle exciting challenges.
