Builder. Problem Solver. Perpetually Curious.
I like understanding how industries work, finding real problems, and building tools that solve them. Currently exploring habit science, developer tooling, and financial systems.
Featured Work

RingTrack
Science-backed habit tracker for Apple Watch
Maximum 3 habits enforced based on cognitive load research. Visualizes progress as activity rings with 66-day automaticity milestones.

Zero-config Python notebooks in Neovim
Eliminates setup friction for Python development in terminal. Auto-creates venvs, detects missing packages, renders matplotlib plots inline.
GitHub →About Me
I'm endlessly curious about how things work — industries, systems, people's workflows. When I spot a real problem, I can't help but think about how to solve it. That's led me to build habit trackers, Neovim plugins, and developer tools that scratch my own itch.
My background spans fund accounting, financial software support, and now software engineering. I've seen systems from every angle — as the user processing transactions, as support debugging issues, and now as the developer building the infrastructure. That perspective shapes how I think about problems.
Right now I'm exploring habit formation science (RingTrack), developer experience (pyworks.nvim), and how AI can improve workflows in regulated industries. I'm also pursuing a Master's in Innovation and Business at AIM.
I'm always interested in understanding new industries and the problems people face.
Tell me about yours.

Building pyworks.nvim: Zero-Configuration Python Notebooks in Neovim
I built a Neovim plugin that brings Jupyter-like notebook workflows to the terminal with zero configuration. Here's why I created it and how it works under the hood.

I got tired of manually creating the same tmux windows every time I switched projects, so I built a tool to automate it and published it as a Homebrew tap....
