I’ve been writing code professionally for 7+ years, building backend systems and data infrastructure.

Recently, I moved into AI platform and infrastructure. This includes building evaluation pipelines, observability and monitoring, MCP servers with proper auth/authz and data governance. Before this, I built data pipelines, observability stacks, and developer tooling across backend and data infrastructure teams.

My path into software started with competitive programming (2x ACM-ICPC regionals participant). That problem-solving foundation shaped how I approach engineering: break down complexity, optimize for performance, understand the system deeply.

I work in the terminal with neovim, tmux, zsh. Type on a Kinesis Advantage360 Pro with a custom ZMK layout. I’ve spent enough time configuring LSPs and keybindings to have opinions about them.

Outside of work, I run and cycle. Completed 300km running and 800km cycling in 2025, which I wrote about in this post.

I write here occasionally about systems, data infrastructure, and things I’m learning.
