I'm a senior software developer with a particular interest in full-stack web development, distributed systems, creative coding, and teaching. I like building real-time messaging systems and tweaking user interfaces.

This account is a scratchpad for personal work and learning. The majority of what you'll find here aren't finished projects, it's more of a rough digital analog of the scratch paper piled around my physical workspace. When I'm working on an idea in my head, I use paper. When I'm working on an idea in software, I use code.

Professionally, I am a full-stack generalist. Right this second I'm building custom, human-scale software for the enterprise integrating AI because it seems like a pretty good idea to me.

Previously, I've worked with:

• Recurly mentoring engineers, building stronger teams, and leading technical projects for subscription management and payment processing
• Stitch Fix on their GraphQL platform team
• USCIS on custom tools the US humanitarian immigration program
• Adafruit Industries on the IoT platform Adafruit IO
• MICA teaching creative coding
• Figure 53 building a theater ticketing platform
• SmartLogic on various contract projects for startups and enterprises
• and an advantage blackjack team you haven't heard of

Here's a few things you'll find in my repositories:

• A Ruby source-to-source translator to convert Rails MySQL create_table statements to Google Cloud Spanner create_table statements.
• Chrome Extensions: Timer, My New Tab
• A Ruby library for generating ULIDs
• A small small coding meetup in Baltimore (pre-COVID 😢)
• An anagram generator
• A pile of teaching materials: Intermedia Studio - Fall 2018, Interactive Spaces - Spring 2019 (and the big project we did), Creative Coding - Fall 2019, and Creative Coding - Spring 2020
• A multi-installation sensor network and data-driven generative bookcover design engine: MICAVIBE. Full story at karlssonwilker.com.
• 1-dimensional cellular automata
• A websocket library for p5.js and corresponding reference server
• A screen recording tool for p5.js sketches so I could turn all my Genuary sketches into tiny videos.
• Some operational transform exploration in Ruby on Rails
• a CRDT based in-browser almost-completely-serverless chat app
