<h2>About me</h2>
<p>I'm a software engineer with broad expertise across several different
disciplines of industry software development, particularly network
programming, full-stack web development, all things cryptocurrency, and
modern cloud-focused devops/Unix systems administration. On the side, I
dabble in 3d graphics, functional programming/type theory, programming
language design, and mucking about with microcontrollers.
<p>I've shipped code in <strong>Rust</strong>, <strong>Python</strong>,
<strong>C/C++</strong>, <strong>Ruby</strong> (on Rails),
<strong>Scala</strong>, <strong>Elm</strong>, and <strong>Haskell</strong>.
My educational credentials are B.A.s in <strong>Linguistics</strong>,
<strong>Computer Science</strong> and <strong>Japanese</strong> from the
<strong>University of California, Berkeley</strong>. My language of choice
for most sorts of software project is Rust these days, but there's a whole
wide world out there of interesting developments in programming language
research - I'd love to write, say, <a href="https://www.idris-lang.org/">Idris</a> for a living one day.
<p>My passion as a software developer is software correctness - I think the
industry as a whole places too little emphasis on writing software that does
the right thing from the beginning. I want to use the best tools and
practices available to write software that is easily maintainable and
minimizes bugs from the start of a project onwards.

<h2>Some personal projects</h2>
<p>A few side projects I've worked on that I think are particularly interesting.</p>
<section>
<h3>Schala</h3>
<p>I've been interested in programming language implementations since my college compilers class,
and interested in type theory ever since I learned about Haskell. <a href="https://code.everydayimshuflin.com/greg/schala">
Schala</a> is a Rust framework I've been sporadically working on to give me a place to experiment with multiple programming
language ideas, and also the name of the language I'm using this framework to implement. Schala is intended to be an
expression-based functional-encouraging programming language using ML-style types with Rust-like syntax.
