Engineering Approach
I work across the full product stack, from requirements and interaction design to backend architecture, data modeling, testing, deployment, and maintenance. I care about turning ambiguous problems into reliable software that people can use in production.
My strongest experience is in TypeScript and Next.js product development, database-backed applications, client-server systems, asynchronous processing, and performance-sensitive game infrastructure.
Outside of software, I enjoy speedcubing, chess, teaching, and experimenting with new product ideas.
