Work

Axiom is a next-generation observability platform at a fraction of the cost of competitors like Splunk and Datadog. My role is to empower the frontend team to ship faster and with more confidence. I also maintain several SDKs.
Create T3 App (20k 🌟) is the best way to start a full-stack, typesafe Next.js app with first-class DX. As a member of the core team I work on all aspects of the project and its future direction.
tRPC (30k 🌟) is a tool for creating end-to-end typesafe APIs. I occasionally contribute to the codebase, but my main focus has been creating educational content and rewriting the docs to make them more welcoming and accessible to new users.
Moody's Analytics is the leader in the KYC space. I shipped features like graph-based RBAC and an end-to-end tool for managing i18n, modernised the frontend tech stack, and upskilled other developers.

Catmash is a game where you and your friends can vote on cats. I built this as a fun activity for the team meetings at Axiom. It uses the Partykit runtime and was included in Sylwia Vargas' presentation at NextConf.
Bad Web Tools is a from-first-principles toolchain for building web apps. The goal is to build everything from scratch, to learn about how the real stuff works. So far I've built a React-like rendering framework with concurrent rendering / reconciliation and a Babel plugin for parsing a subset of JSX. Future ideas include a router, data fetching / network state library, bundler, test runner, package manager, monorepo tooling, etc.
I completed Advent of Code in 2022. Not sure yet if I'll do it in 2023.
Vocab Learn Order is a tool that helps language learners determine which words to learn. Initially created for myself to help me pass the JLPT N1 with significantly fewer hours spent than most learners, it is now used by dozens of language learners every day.
