Work Experience

Freelancer

2018 - PRESENT

Self-employed

Maintained web app and high-volume web scraping pipeline and launched new products as a 1-person engineering team for a property management startup that was later acquired. Worked as a full-stack DevOps using Go, Python, Django, TensorFlow, and DigitalOcean.
Rescued gardening calendar Kickstarter, which had deadly performance issues one week from launch, and helped onboard the first few months of customers. Used Ruby on Rails and Stimulus.
Guided and cleaned up the software stack of a successful startup with "freelancer syndrome." Shortened time to add new features by 3/4 by adding integration testing infrastructure, all while adding new features using Go and Node.js.

Inventor

2019 - 2021

Programming Language Research

Built a prototype for the (possibly) world's first functional graphical structured code editor and used it to solve the majority of 2020's Advent of Code coding challenges.
Utilized WebAssembly to get the prototype working both on the desktop and the browser.
Learned Rust to a near-expert level and became proficient in Haskell and OCaml.

Led the development of Remind for Schools program, which gave bulk controls and reporting to school administrators.
Kept the infrastructure running healthily at all hours of the day, by setting up monitoring graphs and alerts.
Made major organization-wide improvements to the developer testing, continuous integration, and error reporting pipelines.

Experience

Yelp Food Delivery

https://www.yelp.com/nearme/delivery

I led the development team that built the first two iterations of the Yelp food delivery platform, connecting Yelp users to food delivery platforms such as Delivery.com and Eat24. It involved Python back-end development, payment processing, partner APIs, and project planning.

Reminder Messages for Teachers and Schools

https://www.remind.com/

I built and maintained most of the company's product features, including one- and two-way messaging between teachers, students, and parents, controls, and bulk reporting for school principals and administrators. I also implemented large-scale back-end optimizations to support the 30 million users.

I'm working on a prototype for a revolutionary graphics-based programming environment and language that I hope can make programming at least 10x more productive, both for beginners and pros.

Check out the link for a super work-in-progress glimpse at the project.
