The most amazing...

...thing I'm currently doing is designing a new kind of graphics-based programming environment that's easier to use for both programmers and non-programmers.


  • Inventor

    2019 - PRESENT
    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 desktop and in the browser.
    • Learned Rust to a near-expert level and became proficient in Haskell and OCaml.
    Technologies: Rust, JavaScript, GUI, Creativity, WebAssembly, Functional Programming, Haskell, OCaml, Design Language
  • Freelancer

    2018 - PRESENT
    • Maintained a web app and a high-volume web scraping pipeline, launched new products, and performed error monitoring and reporting as a one-person engineering team for a startup (DevOps, back and front end) with Go, Python, Django, and DigitalOcean.
    • Mentored beginner programmers in Python and experienced industry professionals in learning Go and helped them find better career opportunities.
    • Developed high-performance Rust code for a cryptocurrency startup.
    Technologies: PostgreSQL, Django, Go, Python, Rust
  • Product and Infrastructure Engineer

    2015 - 2018
    • Built a one-way messaging and two-way chat system connecting over 30 million teachers and students, with users in almost every school in the US.
    • Designed and implemented many large-scale infrastructure changes to support the growing user-base and engineering organization, e.g., migrating from PostgreSQL to DynamoDB and introducing GraphQL.
    • 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.

    • Implemented a web-based single site authentication system that worked on top of Active Directory.
    • Administered Linux and Solaris servers.
    • Built internal tools like wikis and blogs so that different branches could share information with each other.

    Technologies: Content Management Systems (CMS), Django, WordPress, PHP, Python, Oracle, Linux


  • Yelp Food 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 and Eat24. It involved Python back-end development, payment processing, partner APIs, and project planning.

  • Reminder Messages for Teachers and Schools

    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.

  • CodeMaestro

    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.
