About

I'm a Software Development Engineer who likes owning things end-to-end: backend, frontend, and everything in between. I care about performance the way gamers do: every millisecond matters. If something needs to be built fast and built right, that's where I do my best work.

300+ weekly npm downloads · 212+ production REST APIs · 13+ zero-downtime deploys a week

I've worked on a variety of projects, from simple websites to complex web applications. Here are a few of my favorites.

Stack Decay Score

Stack Decay Score

A dependency health monitoring dashboard that scores 1000+ packages from npm, PyPI, and crates.io on a 0–100 scale across security, maintenance, end-of-life, community, and licensing using OSV and GitHub Advisory data. An Express + MongoDB backend with Redis/BullMQ queues processes concurrent scans, cutting repeat analysis time by 60% via cached results and webhook-triggered re-scans, while React dashboards add trend analysis, dependency-tree visualization, PDF/CSV export, and weekly digest emails.
